## How does Bootstrap's test suite work?
Bootstrap uses [QUnit](http://api.qunitjs.com/), a powerful, easy-to-use JavaScript unit test framework. Each plugin has a file dedicated to its tests in `unit/<plugin-name>.js`.
* `unit/` contains the unit test files for each Bootstrap plugin.
* `vendor/` contains third-party testing-related code (QUnit and jQuery).
* `visual/` contains "visual" tests which are run interactively in real browsers and require manual verification by humans.
To run the unit test suite via [PhantomJS](http://phantomjs.org/), run `grunt test-js`.
To run the unit test suite via a real web browser, open `index.html` in the browser.
## How do I add a new unit test?
1. Locate and open the file dedicated to the plugin which you need to add tests to (`unit/<plugin-name>.js`).
2. Review the [QUnit API Documentation](http://api.qunitjs.com/) and use the existing tests as references for how to structure your new tests.
3. Write the necessary unit test(s) for the new or revised functionality.
4. Run `grunt test-js` to see the results of your newly-added test(s).
**Note:** Your new unit tests should fail before your changes are applied to the plugin, and should pass after your changes are applied to the plugin.
## What should a unit test look like?
* Each test should have a unique name clearly stating what unit is being tested.
* Each test should test only one unit per test, although one test can include several assertions. Create multiple tests for multiple units of functionality.
* Each test should begin with [`assert.expect`](http://api.qunitjs.com/expect/) to ensure that the expected assertions are run.
* Each test should follow the project's [JavaScript Code Guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#js)
### Example tests
```javascript
// Synchronous test
QUnit.test('should describe the unit being tested', function (assert) {
assert.expect(1)
var templateHTML = '<div class="alert alert-danger fade in">'
+ '<a class="close" href="#" data-dismiss="alert">×</a>'
+ '<p><strong>Template necessary for the test.</p>'
+ '</div>'
var $alert = $(templateHTML).appendTo('#qunit-fixture').bootstrapAlert()
$alert.find('.close').click()
// Make assertion
assert.strictEqual($alert.hasClass('in'), false, 'remove .in class on .close click')
})
// Asynchronous test
QUnit.test('should describe the unit being tested', function (assert) {
assert.expect(1)
var done = assert.async()
$('<div title="tooltip title"></div>')
.appendTo('#qunit-fixture')
.on('shown.bs.tooltip', function () {
assert.ok(true, '"shown" event was fired after calling "show"')
done()
})
.bootstrapTooltip('show')
})

<p>Navigate to the radio button group with the keyboard (generally, using <kbd>TAB</kbd> / <kbd>SHIFT + TAB</kbd>).

# attribute与property
## attribute属性
* HTML中的预定义与自定义属性, 在js中被一个叫做attributes的property所维护
## property属性
* JS原生对象的直接属性
## 两者间的转换关系
### 对非布尔值属性而言
* 实时同步
### 对布尔值属性而言
* property永远不会同步attribute
#### 没有修改过property时
* attribute会同步property
#### 没有修改过property时
* attribute不会再同步property
* 在浏览器中被识别的和用户所操作的都是property
# H5中的一些小功能
## class
* 由于class是关键字因此JS可以通过className属性来访问标签的class值
* 直接使用className来添加删除class不够方便, H5新增了classlist对象属性
* classlist是个伪数组, 其中有add, remove, toggle方法来增删class
## 自定义属性
* 在H4中只能通过setAttribute方法来修改自定义HTML属性
* 在H5中新增dataset对象来保存自定义的HTML属性
* 想要将自定义属性添加到dataset对象时需要以data-开头, 自定义HTML属性使用-分隔单词(`data-my-test`)
* 在dataset对象中, 自定义HTML属性以驼峰命名法表示(`myTest`)
## 文本可编辑
* 新增HTML属性contentEditable, 值必须为true否则无法开启
# HTML5
* HTML5是定义HTML标准的最新版本, 表示两种概念
* 它是一个新版本的HTML语言, 具有新的元素, 属性和行为
* 它有个更大的技术集, 允许更多样化和强大的网站和应用程序
## H5优势
* 跨平台
* 快速迭代
* 降低成本
* 导流入口多
* 分发效率高
## H4与H5的差别
1. DOCTYPE, 或者称为Document type declaration, 文档类型声明, 缩写为DTD
2. document.combatMode 返回浏览器的渲染模式
* css1Combat 标准模式
* css1Combat 近似标准模式
* backCombat 怪异模式
3. 在IE9以上或者其他浏览器在三种渲染模式中几乎没有区别
4. 在IE7,8,9中理论上存在怪异模式，但实际只有标准模式
5. 在IE6中怪异模式与标准模式区别最大
6. 在IE5中只有怪异模式
7. html与head标签中HTML5内嵌了H4的许多属性
8. head中的meta标签指定了http的头消息
## 语义化标签
1. hgroup 包裹多个h1，h2...等
2. nav 导航栏
3. header 表示标题栏, 如果hgroup能够表现语义可以不使用
4. section 单独的模块
5. footer 脚注
6. article 单独的文章
7. aside 文章附属内容
## canvas
* 可以使用闭合和成对标签，不推荐使用闭合标签
* canvas是HTML5新增的元素，可以使用js脚本来绘制图片，最早由apple引入webkit
* 默认width为300，height为150，背景颜色默认继承
* 不能使用css来为canvas设置高宽，否则会在绘制时出错，会被拉伸
* 在canvas标签中添加内容可以使这些内容在浏览器不支持canvas时显示
* 获取canvas节点后只有width, height属性, getContext,isPointInPath,toDataURL方法可以使用
* 获取渲染上下文
```javascript
var canvasNode = document.querySelector('canvas') //此api只能获取当前页面的快照节点
if(canvasNode.getContext){ //检查兼容性
context = canvasNode.getContext('2d') //只有一个参数为2d，3d图形需要webGL
}
```
### 绘制矩形
#### 同步绘制, 所得即所见
#### canvas的基本图形为矩形，只调用一个api只能绘制一个矩形
* 绘制实心矩形`context.fillRect(x轴, y轴，宽，高)`
* 绘制空心矩形`context.strokeRect(x轴, y轴，宽，高)`
* canvas在实现绘制空心矩形时会在指定位置的上下/左右各绘制0.5px的边框，但是浏览器渲染时会向上取整实际成为2px的边框。
* 如果只想要绘制1px边框需要给x轴与y轴的实际位置多0.5
* 若想在距离画布左或上100px的位置绘制图形，则`context.strokeRect(100.5, 100.5，100，100)`
* 绘制实心的透明矩形`context.clearRect(x轴, y轴，宽，高)`
* 设置实心矩形的颜色`context.fillStyle = string` 可以使用rgba
* 设置空心矩形的边框颜色`context.strokeStyle = string` 可以使用rgba
* 设置空心矩形的边框宽度`context.lineWidth = number`, 会给边框的左右/上下同时设置为lineWidth一半的值, 参数不可为负值
* 设置两条线交汇时的形状`context.lineJoin = string`, 参数为miter(默认)，round(圆角)，bevel(斜角)
#### canvas的基本元素为路径
* 绘制直线
* beginPath() //清除路径容器中的内容
* moveTo(x, y) //将画笔抬起移至指定路径
* lineTo(x, y) //将路径从上一个位置平移至指定路径
* closePath() //使路径自动形成闭环
* stroke() //按照路径绘制直线, 绘制规则同strokeRect不会自动执行closePath
* fill() //按照路径自动填充内部, 会自动执行closePath
* rect(x, y, width, height) //创建一个矩形路径
* lineCap=butt(默认值)| round(圆角) | square(矩形) //指定线段的两端样式, 除第一种参数外都会增加线段的长度
* 绘制圆形
* `arc(x, y, radius, start, end)` 起始位置为画布x轴, end与start只能是弧度, 绘制方向为顺时针
* `arcTo(x1, y1, x2, y2, radius)` 需要先用moveTo指定一个起始点，再加上参数中两个点来表示一个角的路径, 最后用半径为radius的圆去与这个角相切得到的路径即为绘制后的结果
* `quadraticCurveTo(x1, y1, x2, y2)` 开始点与arcTo相同, 参数用来指定二次贝塞尔曲线的控制点与结束点
* `bezierCurveTo(x1, y1, x2, y2， x3, y3)` 三次贝塞尔曲线，前两种参数指定两个控制点位置，最后一种参数指定结束点的位置
#### save()与restore()
* 路径容器
* 堆结构
* 每次调用路径api时会向路径容器添加路径信息
* 调用beginPath时清空
* 样式容器
* 堆结构
* 每次调用样式api时在样式容器中覆盖原样式
* 调用save()时向样式堆压栈, 没有调用过样式api时保存的是初始化样式
* 样式栈
* 栈结构
* 调用restore()时会弹栈，并且将弹出栈的样式应用给样式容器
* 样式栈中会保存样式属性与变换位置
```javascript
//使用canvas的标准格式
context.save() //压入样式栈, 保存的是初始化样式
context.strokeStyle('pink') //覆盖样式容器
context.beginPath() //清空路径容器
context.stroke() //绘制
context.restore() //弹出样式栈
context.save() //压入样式栈, 保存的是初始化样式
context.strokeStyle('green') //覆盖样式容器
context.beginPath() //清空路径容器
context.stroke() //绘制
context.restore() //弹出样式栈
```
#### canvas变换
##### canvas中的变换都为累加操作, 不会覆盖
##### 整个canvas公用一个原点
* tanslate(x, y)
* 移动画布的坐标轴原点
* rotate(arc)
* 旋转画布的坐标轴
* 参数为弧度
* scale(x, y)
* 放大缩小画布中像素所占面积
* x和y控制在画布中的1像素的长宽实际在画布中占用的像素大小, 例如scale(2, 2), 画布中设定的1像素长宽会变为2像素
* 需要注意在css中的像素是一个抽象概念, 面积可以变大缩小, 默认1像素就是长宽为1像素的大小
### 使用图片
* drawImg(img, x, y, width, height)
* 使用图片与渐变应用给canvas, 需要将返回值赋值给fillStyle才会生效
* createPattern(img, [repeat|no-repeat|repeat-x|repeat-y])
* `createLinearGradient(x1, y1, x2, y2)` 指定渐变方向
* `gradient.addColorStop(0, 'red')` 添加渐变颜色，gradient是createLinearGradient的返回值
* `createRadialGradient(x1, y1, radius1, x2, y2, radius2)` 指定渐变方向
* `gradient.addColorStop(0, 'red')` 添加渐变颜色，gradient是createRadialGradient的返回值
### 绘制文本
* `fillText(text, x, y)`绘制字体
* `font='size family'` 大小字体缺一不可
* `strokeText(text, x, y)`绘制字体边框
* `textAlign = 'center|left|right'`决定字体与x, y原点的关系
* `textBaseline = 'middle|top|bottom'` 决定字体与基线的关系
* `measureText()` 返回字体在画布上的宽度
* `shadowOffsetX = float`
* `shadowOffsetY = float`
* `shadowBlur = float`
* `shadowColor = color`
* canvas的字体垂直水平居中
```javascript
ct.font = '60px sans-serif'
ct.fillText('aaa', 0, 0)
var a = ct.measureText('aaa')
ct.fillText('aaa', canvas.width/2 - a/2, canvas.height/2 - 60/2)
```
### 像素操作
* getImageData(x1, y1, x2, y2) 获取指定范围内的像素数据，返回值为imageData
* imageData
* width 水平方向上的像素数量
* height 垂直方向上的像素数量
* data 数组，每一个像素点的rgba的数据
* putImageData(imageData, x, y) 将指定像素数据绘制到canvas上
* createImageData(x, y) 创建一块像素信息
### canvas合成
* 全局透明度 globalAlpha = value 设置整个画布的透明度
* globalCompositeOperation source源指新图片，destination指老图片
* source-over 使源置于目标之上
* source-in 只显示源与目标重叠的源那部分
* source-out 只显示源与目标没有重叠的源那部分
* source-atop 在source-over基础上不显示源超出目标的那部分
* destination-over 使目标置于源之上
* destination-in 只显示目标与源重叠的目标那部分
* destination-out 只显示目标与源没有重叠的目标那部分
* destination-atop 在destination-over的基础上不显示目标超出的那部分

# less预处理器
LESS是一种动态样式语言扩展了CSS的功能添加了变量, Mixin, 函数等特性
* 可以通过客户端编译
引入less编译的js文件, 会增加客户端加载速度
* 可以通过服务端编译
通过nodejs实现
* 可以通过预编译转化成css文件再从html引入
使用[考拉编译器](www.koala-app.com)
## 注释
通过//编写的注释在编译成css后不会暴露
通过/**/编写的注释才会暴露
## 变量
### 变量为延迟加载
整个文件加载完后才给变量赋值，因此某个变量值可能是在这行语句后面定义的值
### 使用@来声明变量
* @color: pink;
* @a: #wrap;
* @b: margin;
* @c: min.jpg;
当变量为选择器，属性名，url时，要用`@{selector|attr|url}`的方式
```less {.line-numbers}
@{a}{
}
.wrap{
@{b}: 20px;
}
.wrap{
background-image: url(@{c});
}
```
当变量为属性值时使用@value的方式
```less {.line-numbers}
.wrap{
color: @color;
}
```
## 嵌套规则
基本嵌套规则为大括号表示父子关系，即两个选择器之间有空格
使用&表示此选择器与上个选择器为兄弟关系，即两个选择器之间没有空格
## less混合(mixin)
混合是将一系列规则集引入另一个规则集中
在less规则中明确定义混合前必须加`.`
### 普通混合
此混合会被当成.center的样式被编译进原生css文件
```less {.line-numbers}
// less:
.center{
width: 20px;
height: 20px;
}
.wrap{
.center
}
//css:
.center{
width: 20px;
height: 20px;
}
.wrap{
width: 20px;
height: 20px;
}
```
### 不带输出的混合
```less {.line-numbers}
// less:
.center(){
width: 20px;
height: 20px;
}
.wrap{
.center()
}
//css:
.wrap{
width: 20px;
height: 20px;
}
```
### 带参数的混合
```less {.line-numbers}
// less:
.center(@a){
width: @a;
height: 20px;
}
.wrap{
.center(100px)
}
//css:
.wrap{
width: 100px;
height: 20px;
}
```
### 多个参数的混合
```less {.line-numbers}
// less:
.center(@a, @b){
width: @a;
height: @b;
}
.wrap{
.center(100px, 100px)
}
//css:
.wrap{
width: 100px;
height: 100px;
}
```
### 有默认值的混合
```less {.line-numbers}
// less:
.center(@a: 20px, @b: 20px){
width: @a;
height: @b;
}
.wrap{
.center(100px)
}
//css:
.wrap{
width: 100px;
height: 20px;
}
```
### 匹配
```less {.line-numbers}
// less:
.triangle(@_, @a, @b){ //此处变量为形参不需要与匹配模式中其他的规则命名相同
width: 100px;
height: 100px;
}
.triangle(A, @c, @d){
border-top: @c @d;
}
.triangle(B, @c, @d){
border-bottom: @c @d;
}
.wrap{
.triangle(A, 100px, solid)
}
//css:
.wrap{
width: 100px;
height: 100px;
border-top: 100px solid;
}
```
### arguments
```less {.line-numbers}
// less:
.center(@a, @b){
border: @arguments;
}
.wrap{
.center(100px, solid)
}
//css:
.wrap{
border: 100px solid;
}
```
## 计算
加减乘除，且可以只有一个数值加单位
```less {.line-numbers}
//less:
.wrap{
border: 100+100px solid;
}
//css:
.wrap{
border: 200px solid;
}
```
## 继承
语法: `:extend()`
混合在被编译成css后，效果等同于将混合规则集复制到另一个混合集中，会造成原生css中有大量的重复声明块
使用继承可以使多个选择器被结合符隔开，提高css性能
被继承的规则写法上必须与普通混合相同，不能加括号也不能有参数
```less {.line-numbers}
//less
.center{
width: 20px;
height: 20px;
}
//第一种写法
.wrap{
&:extend(.center);
&:first-child{
background-color: red;
}
}
//第二种写法
.wrap:extend(.center){
&:first-child{
background-color: red;
}
}
//css:
.center,
.wrap{
width: 20px;
height: 20px;
}
.wrap:first-child{
background-color: red;
}
```
## 避免编译
当在less使用运算时可以指定某些运算不被预编译，直接将运算过程赋值给原生css时可以使用此功能
```less {.line-numbers}
//less:
.wrap{
border: ~(100+100px) solid;
}
//css:
.wrap{
border: 100+100px solid;
}

# 容器
## 流体布局
`class="container-fluid"`
`width: auto`
## 固定容器
`class="container"`
固定容器特性
```less
//阈值
@screen-xs: 480px;
@screen-xs-min: @screen-xs;
@screen-phone: @screen-xs-min;
@screen-sm: 768px;
@screen-sm-min: @screen-sm;
@screen-tablet: @screen-sm-min;
@screen-md: 992px;
@screen-md-min: @screen-md;
@screen-desktop: @screen-md-min;
@screen-lg: 1200px;
@screen-lg-min: @screen-lg;
@screen-lg-desktop: @screen-lg-min;
@grid-gutter-width: 30px;
```
|响应式阈值|width|
|:------:|:---:|
|大于1200(lg)|1170(1140+槽宽30)|
|大于等于992小于1200(md)|970(940+槽宽30)|
|大于等于768(sm)|750(720+槽宽30)|
|小于768(xs)|auto|
## 栅格布局
被容器包裹，一行默认被分成12份
### 栅格grid源码分析
1.流体容器与固定容器公共样式
容器的左右外边距为`auto`, 左右内边距为`15px`
```less
.container-fixed(@gutter: @grid-gutter-width) {
margin-right: auto;
margin-left: auto;
padding-left: floor((@gutter / 2)); //15px
padding-right: ceil((@gutter / 2)); //15px
&:extend(.clearfix all);
}
```
2.固定容器特定样式
根据媒体查询结果设置容器宽度
```less
.container {
.container-fixed();
@media (min-width: @screen-sm-min) {
width: @container-sm;
}
@media (min-width: @screen-md-min) {
width: @container-md;
}
@media (min-width: @screen-lg-min) {
width: @container-lg;
}
}
```
3.流体容器特定样式
```less
.container-fluid {
.container-fixed();
}
```
4.行特定样式
将每一行的左右外边距设为`-15px`, 与容器的内边距重叠
```less
.row {
.make-row();
}
.make-row(@gutter: @grid-gutter-width) {
margin-left: ceil((@gutter / -2));
margin-right: floor((@gutter / -2));
&:extend(.clearfix all);
}
```
5.列特定样式
初始化列公共样式
```less
.make-grid-columns();
.make-grid-columns() {
// 对lg, md, sm, xs四种情况, 都会将一行分成@grid-columns份, 此处为12
.col(@index) { // 初始化列样式
@item: ~".col-xs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}";
.col((@index + 1), @item);
}
.col(@index, @list) when (@index =< @grid-columns) { // 递归
@item: ~".col-xs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}";
.col((@index + 1), ~"@{list}, @{item}");
}
.col(@index, @list) when (@index > @grid-columns) { // 递归出口
@{list} {
//设置相对定位以便每一列能够开启列排序
position: relative;
// 设置最小高度防止没有内容时元素坍塌
min-height: 1px;
// 通过槽宽来设置内边距
padding-left: ceil((@grid-gutter-width / 2));
padding-right: floor((@grid-gutter-width / 2));
}
}
.col(1); // 开启样式
}
```
根据媒体查询来决定开启哪种特定样式
```less
//手机优先，当以下三种媒体查询没有效果时默认使用此样式, 否则按照从小到大的顺序覆盖
.make-grid(xs);
@media (min-width: @screen-sm-min) {
.make-grid(sm);
}
@media (min-width: @screen-md-min) {
.make-grid(md);
}
@media (min-width: @screen-lg-min) {
.make-grid(lg);
}
//混合匹配, 用来分别设置width, pull, push, offset的样式
.loop-grid-columns(@index, @class, @type) when (@index >= 0) {
.calc-grid-column(@index, @class, @type);
// 下一步迭代
.loop-grid-columns((@index - 1), @class, @type);
}
//设置列样式
.make-grid(@class) {
.float-grid-columns(@class);
.loop-grid-columns(@grid-columns, @class, width);
.loop-grid-columns(@grid-columns, @class, pull);
.loop-grid-columns(@grid-columns, @class, push);
.loop-grid-columns(@grid-columns, @class, offset);
}
```
### 以`.make-grid(xs)`为例
#### 运行`.float-grid-columns(@class)`混合
设置`class`为`col-xs-1, col-xs-2, ..., col-xs-12`的浮动样式
```less
.float-grid-columns(@class) {
.col(@index) { // 初始化列样式
@item: ~".col-@{class}-@{index}";
.col((@index + 1), @item);
}
.col(@index, @list) when (@index =< @grid-columns) { // 递归
@item: ~".col-@{class}-@{index}";
.col((@index + 1), ~"@{list}, @{item}");
}
.col(@index, @list) when (@index > @grid-columns) { // 递归收尾, 给所有选择器添加浮动
@{list} {
float: left;
}
}
.col(1); // 开启列样式
}
```
#### 运行`.loop-grid-columns(@grid-columns, @class, width)`混合
设置`class`为`col-xs-1, col-xs-2, ..., col-xs-12`的`width`
```less
.calc-grid-column(@index, @class, @type) when (@type = width) and (@index > 0) {
.col-@{class}-@{index} {
width: percentage((@index / @grid-columns));
}
}
```
#### 运行`.loop-grid-columns(@grid-columns, @class, push)`混合
设置`class`为`col-xs-1, col-xs-2, ..., col-xs-12`的列排序
```less
.calc-grid-column(@index, @class, @type) when (@type = push) and (@index > 0) {
.col-@{class}-push-@{index} {
//列排序由left实现
left: percentage((@index / @grid-columns));
}
}
.calc-grid-column(@index, @class, @type) when (@type = push) and (@index = 0) {
.col-@{class}-push-0 {
//为了使递归中不将left设置为0px因此单独挑出@index=0时设置值为auto
left: auto;
}
}
```
#### 运行`.loop-grid-columns(@grid-columns, @class, pull)`混合
与`push`的区别仅仅在于此处设置的是相对定位的`right`而非`left`
因此对不同阈值不能跳跃设置列排序, 可能会发生`left`, `right`冲突或者未覆盖的情况
#### 运行`.loop-grid-columns(@grid-columns, @class, offset)`混合
设置`class`为`col-xs-1, col-xs-2, ..., col-xs-12`的列偏移
```less
.calc-grid-column(@index, @class, @type) when (@type = offset) {
.col-@{class}-offset-@{index} {
//列偏移由外边距实现
margin-left: percentage((@index / @grid-columns));
}
}
```
## 响应式工具
```less
.responsive-visibility() {
display: block !important;
table& { display: table !important; }
tr& { display: table-row !important; }
th&,
td& { display: table-cell !important; }
}
.responsive-invisibility() {
display: none !important;
}
//初始化所有样式为隐藏
.visible-xs,
.visible-sm,
.visible-md,
.visible-lg {
.responsive-invisibility();
}
//将符合条件的元素显示出来
.visible-xs {
@media (max-width: @screen-xs-max) {
.responsive-visibility();
}
}
.visible-xs-block {
@media (max-width: @screen-xs-max) {
display: block !important;
}
}
.visible-xs-inline {
@media (max-width: @screen-xs-max) {
display: inline !important;
}
}
.visible-xs-inline-block {
@media (max-width: @screen-xs-max) {
display: inline-block !important;
}
}
//将符合条件的元素隐藏
.hidden-xs {
@media (max-width: @screen-xs-max) {
.responsive-invisibility();
}
}
.hidden-sm {
@media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) {
.responsive-invisibility();
}
}
.hidden-md {
@media (min-width: @screen-md-min) and (max-width: @screen-md-max) {
.responsive-invisibility();
}
}
.hidden-lg {
@media (min-width: @screen-lg-min) {
.responsive-invisibility();
}
}
```
## 栅格盒模型的精妙之处
### 回顾栅格的基本规则
* 固定容器拥有左右内边距15px
* 行两边有-15px的外边距
* 列两边有15px的内边距
1. 为了维护槽宽的规则列里面应该内边距隔开相邻列内的文本
2. 当列里面放行行里又有子列时, 为了不让被行里面的子列内的文本与跟行外面那个列相邻列内的文本的边距扩大, 需要给行设置负的外边距使任意嵌套关系的两列内边距恒定为30px
3. 当给容器内放行时, 必须给容器设置内边距才能抵消行的外边距的副作用
## bootstrap的定制化
* 修改源码
bootstrap的入口文件为bootstrap.less, 里面的import为less的特性, 起着整合其他less的功能而不是css中发出新请求的功能, 可以经常使用
可以通过修改源码后重新编译bootstrap.less再引入新css文件
* 创建新的入口文件
将bootstrap的入口文件当做混合引入到新的入口文件中
接下来修改想要修改的变量或样式
最后将新入口文件编译引入

# 层叠样式表cascading style sheet
* 嵌入式样式
将style当做元素的属性, 将所有样式写在style中, 只对当前元素起作用, 不方便复用, 不推荐使用
* 内联样式
在内部引入style标签
* 外联样式
从外部引入style标签, 可以利用浏览器缓存加快用户访问速度, 最推荐使用, link原本的目的是用来链入外部文档，用rel(relation)表示当前文档与外部文档之间的关系
`<link rel="stylesheet" type="text/css" href=""></link>`
## 语法
### 选择器
使用选择器语法选择相应的元素
### 声明块
使用{}, 为名值对结构, 不同声明使用;来分隔, 名值之间使用:来连接
## 块元素
独占一行的元素, 无论内容多少都一定独占一行
div, h1, h2..., p, br等
div没有语义, 为了设置块元素样式
## 内联元素
只占自身大小的元素, 不会占用一行
span,a,img,iframe
span没有语义, 用来选择一段文字来设置样式
一般情况下使用块布局, 使用内联元素修改样式并且使用块元素包含内联元素
a元素可以包含任何元素但不能包含本身
p元素不能包含任何块元素
## 元素之间的关系
父元素
子元素
祖先元素
后代元素
兄弟元素
## 子元素选择器 >
IE6及以下没有子元素选择器
伪类表示某个元素的某种状态
如: `:link, :visited, :hover, :active, :focus, ::selection, ::before, ::after`
浏览器通过历史记录判断是否访问过网页, 因为有关用户隐私所以通过visited只能设置字体颜色
伪类可以在IE6以外的浏览器中为除a元素以外的元素设置属性
active表示点击时的状态
hover表示鼠标移入, IE6中只能对a元素设置
focus表示获取了鼠标焦点时
selection表示文字内容被选中, 当使用火狐时用-moz-selection来兼容
伪元素表示元素中的特殊位置, IE6及以下不支持
:first-letter 元素中第一个字母
:first-line 元素当前行
:before 表示元素最前边部分,一般都要结合content一起使用
:after 表示元素后面部分
以下只对IE9及以上支持
属性选择器[]
语法:
[属性名]
[属性名="属性值"]
[属性名^="属性值"] 以属性值开头的
[属性名$="属性值"] 以属性值结尾的
[属性名*="属性值"] 包含指定属性值的
子元素选择器
语法:
:first-child 第一个子元素
:last-child 最后一个子元素
:nth-child(num) 指定位置子元素, 其中num可以是数字,even(偶数),odd(奇数)
在当前类型的子元素中排列
:first-of-type
:last-of-type
:nth-of-type
兄弟选择器
语法:
+后面第一个兄弟元素
~后面所有兄弟元素
否定伪类
从已选中的元素中剔除某些元素
语法:
:not(选择器)
>祖先元素上的样式会被后代元素继承但是不是所有样式会被继承如背景相关样式
## 优先级的规则
内联样式>id选择器>类和伪类>元素选择器>通配*>继承的样式
优先级相加判断显示哪种样式
可以在样式的最后添加一个!important来提高优先级
## 长度单位
像素 px 显示效果越好的显示屏, 像素越小
- 手机浏览器会自动将实际像素大小乘以4来显示
百分比 % 根据父元素的大小来计算样式, 当父元素属性发生变化时, 子元素也会发生改变
- 自适应时常用
em 和百分比类似, 相对于当前元素字体大小来计算
-1em = 1 font-size
## 颜色单位
直接使用单词表示
- red, blue
RGB(红色浓度, 绿色浓度, 蓝色浓度)
- 可以是0-255的数字
- RGB(111,222,123)
- 可以是0%-100%的百分比
- RGB(50%,50%,50%)
- 使用16进制来表示, 三组两位来表示, 每一组为00-ff, 当两位相同时可以简写
- #0000ff /#00f
## 字体
字体颜色 color:
- 指定字体颜色, 会继承给border-color
字体大小 font-size:
- 设置的不是字体本身大小, 而是一个看不见的框的高度, 字在这个框中, chrome最小就支持12px,可以设置为0使内联元素间的距离清除
字体样式 font-style:
- normal
- italic 斜体
- oblique 倾斜
大部分浏览器都不会区分这两者
字体粗细 font-weight:
- normal
- bold 加粗
也可以指定100,200, ..., 900等9种粗体, 但是用户电脑往往没有那么多字体所以可能达不到想要的效果
font-variant 设置小型大写字母
- normal
- small-caps
所有字母用大写表示但是小写字母用比较小的大写字母显示
字体 font-family:
- 指定字体, 当采用某种字体如果浏览器支持则使用指定字体, 否则使用默认字体
- 该样式可以同时指定多个字体, 优先显示排在前面的字体, 没有再使用下一个
- 浏览器使用的是计算机中的字体, 有则使用没有则不使用, 尽量不要使用奇怪的字体
- font-family: arial,微软雅黑
字体分类
- 在网页中将字体分为五大类, 浏览器自动选取属于这些类中的字体来显示, 一般将大分类指定为font-family的最后一种字体
- serif 衬线字体即有笔锋
- sans-serif 非衬线字体即无笔锋
- monospace 等宽字体即每个字一样宽
- cursive 草书字体
- fantasy 虚幻字体
可以使用font来设置所有与字体相关的样式, 不同样式之间用空格隔开
- 斜体 加粗 小型大写字母顺序可变且可不写
- 文字大小和字体必须写, 不写就将字体样式全部应用默认值
- 性能较分开写更好
## 行间距
只能通过设置行高来间接设置行间距
- line-height
- 使用大小表示
- 使用百分数表示
- 使用一个数值表示字体大小的倍数
文字会默认在行高中垂直居中显示
行间距 = 行高 - 字体大小
- 对于单行文本可以将行高设置与父元素高度一致使文本居中
可在font中设置行高, 行高值是字体大小加斜杠后设置
- font: 30px/30px "微软雅黑"
- 当使用font时其他在font中未指定的值都会变成默认值, 因此其他与字体相关的属性都要写在font之后
## 文本
text-transform 设置大小写
- none
- capitalize 单词首字母大写, 用单词边界区分单词
- uppercase 全部大写
- lowercase 全部小写
text-decoration 定义文本的线条
- none
- underline 下划线
- overline 上划线
- line-through 中线
超链接会默认设置下划线, 要去除时要用此属性
letter-spacing 字符间距
- 中文也会起作用
word-spacing 单词间距
- 本质是单纯设置空格的大小
text-align 文本对齐方式
- left 靠左对齐
- right 靠右对齐
- center 居中对齐
- justify 两端对齐(通过调整文本间大小来对齐)
text-indent 设置首行缩进 IE6,7中可能会让父元素一起缩进
设置正值向右缩进指定像素
设置负值向左缩进指定像素
text-indent: 2em;
可以用来隐藏一段文字
- text-indent: -9999px;
## 盒子模型
由内容区, 内边距, 边框, 外边距组成
设置边框
三种样式缺一不可
- border-width
- border-color
- border-style
每种属性都可以通过写入不同数量的属性值来表示不同方向应用哪些属性
也可以使用
- border-left-width 等来规定特定方向的属性
大部分浏览器边框宽度和颜色有默认值但是style默认值为none
所以只设置style时就有边框显示
可以使用border统一设置, 没有顺序要求, border只能指定4个边的样式都相同不能分别指定
- border： 10px blue solid；
可以使用border-top, border-bottom等来分别设置
设置内边距
padding可以一次性写明上下左右
设置外边距
不影响可见框的大小而是影响定位
margin可以一次性写明上下左右
左上的margin值影响元素本身的定位, 右下的margin值影响相邻元素的位置
当值为负时, 元素向反方向移动
水平方向设置为auto时将会设置成最大值
垂直方向设置为auto时会设置成0
当left与right都设置成auto时, 两值会相同因此可这样设置使元素居中
垂直外边距的重叠
- 元素间相邻的垂直方向的外边距会取最大值而不是相加
- 兄弟之间
- 父子元素之间, 当子元素设置上边距时如果父子元素上边距相邻, 父元素会使用子元素的上边距, 可使用padding, border等隔开使其不相邻而不生效
## 浏览器默认
浏览器为了在没有设置样式时也可读会给标签设置默认样式, 但是许多默认样式是不需要的
可以用margin, padding赋值为0来覆盖
## 内联元素的盒模型
内联元素不能设置宽和高
可以设置内边距但垂直内边距不影响页面布局, 水平内边距会影响
可以设置边框但是垂直边框不影响布局, 水平会影响
可以设置水平外边距且不会重叠, 不能设置垂直外边距
## 将内联元素设置为块元素
display
- inline 内联元素
- block 块元素
- inline-block 行内块元素, 可以使元素既可以设置宽高等且不会独占一行
- none 不显示元素且不占位与visibility:(visible/hidden)相似, 但后者会占位
## 溢出
子元素理论上小于等于父元素的内容区但有时候会大于父元素的内容区, 此时叫溢出
可以使用overflow处理
可选值
- visible 默认值
- hidden 隐藏溢出内容
- scroll 滚动查看溢出内容, 无论是否溢出都会添加滚动条
- auto 根据需求是否添加滚动条
## 文档流
文档流在网页最底层, 表示页面的位置, 所创建的元素默认在文档流中
元素在文档流中的特点
块元素
1.在文档流中独占一行自上向下排列
2.块元素在文档流中默认宽度是100%, 宽度值是auto
3.块元素在文档流中的高度默认被内容区撑开
内联元素
1.内联元素在文档流中只占自身大小, 默认从左向右排列, 如果一行不够容纳则换到下一行继续自左向右
2.文档流中, 内联元素宽度和高度默认被内容撑开
## float
可以使用它来使块元素脱离文档流
使元素浮动后, 这个元素会向上浮动直到碰到父元素的边框或者其他浮动元素就会停止
如果浮动元素上面是没有设置浮动的块元素则浮动元素不会超过块元素
在IE6中上面元素如果是内联元素也不会超过那个内联元素
如果一行无法容纳浮动元素则会自动换行
浮动的元素不会超过它上边的兄弟浮动元素, 即处于其下方或平行
浮动的元素不会盖住文字, 文字会自动环绕在浮动元素周围
在文档流中元素宽度默认值是父元素的全部, 当浮动脱离文档流后高度和宽度默认由内容决定
内联元素脱离文档流后表现与块元素脱离后相同
- none 默认值, 不浮动
- left 向左浮动
- right 向右浮动
浮动练习
## 高度塌陷问题
在文档流中父元素默认被子元素撑开, 子元素多高, 父元素也多高
当给子元素设置浮动, 子元素会完全脱离文档流此时将会导致子元素无法撑起父元素的高度造成高度塌陷
这会导致布局混乱需要解决
- 将高度写定, 但父元素无法适应子元素高度, 因此不推荐使用
在页面中元素有隐藏属性block formatting context
简称BFC, 该属性可以打开或关闭, 默认关闭
当开启BFC时元素有以下属性：
- 父元素垂直外边距不会和子元素重叠
- 不会被浮动元素覆盖
- 可以包含浮动元素
开启BFC有如下方法：
- 设置元素浮动
会导致父元素宽度丢失, 且之后的元素上移, 不推荐
- 设置绝对定位
- 设置为inline-block
宽度会丢失, 不推荐使用
- overflow设置为非visible值
此元素内部的相对定位元素如果超出内容区会被隐藏
这些方法中将overflow设置为hidden或者auto副作用最小
IE6及以下不支持BFC, 因此使用此方式不兼容BFC
IE6有类似属性叫做hasLayout
开启此属性有以下方法：
- zoom: 1 将元素放大几倍
- min-height/max-height/min-width/max-width:除none
- 绝对定位
## 清除浮动
有时希望其他元素浮动时对当前元素不产生影响, 使用clear样式
clear用来清除其他元素对当前元素的影响, 可选值：
- none 默认值
- left 清除影响最大的左侧浮动元素的影响
- right 清除影响最大的右侧浮动元素的影响
- both 清除两边中影响最大的浮动元素的影响
## 解决高度塌陷方式2
使用清除浮动的方式解决高度塌陷, 在浮动元素后增加一个带有clear属性的空白块元素来撑起高度
可使用伪类.clearfix:after来在不修改html结构的情况下解决问题(clearfix为浮动元素的父元素)
IE6及以下不支持此伪类, 使用:
.clearfix{
zoom: 1;
}
来兼容
table添加在子元素前时可以解决父子元素上外边距重叠问题, 为了不改变html结构使用：
.clearfix:before,
.clearfix:after{
content: "";
display: table;
clear: both;
}
可以同时解决上外边距重叠与高度塌陷问题
## ps基本操作
编辑->首选项->文件与标尺->修改为像素
ctrl+2 打开/关闭标尺
alt+滚轮 放大缩小图片
F8 打开选取框的颜色大小信息
从标尺中拖出辅助线
按住alt取色
## 定位
将元素移动到页面的指定位置
position
可选值：
- static 默认值, 没有开启定位
- relative 相对定位
开启元素相对定位不设置偏移量时页面不会产生任何变化
可以通过left, right, top, bottom来设置元素偏移量
如果没有开启定位会忽略以上属性
相对定位是元素相对原本在文档流中的位置进行定位
相对定位会使元素提升层级, 定位元素会盖住文档流中的元素
相对定位不会改变元素的性质, 块元素和内联元素这个性质不会变化
- absolute 绝对定位
开启此定位会使元素脱离文档流
开启此定位不设置偏移量元素的位置不会发生变化
绝对定位是相对于开启了定位的最近的祖先元素进行定位
如果所有祖先元素都没有开启定位则会相对于浏览器窗口进行定位(一般来说开启绝对定位都会开启父元素的相对定位)
绝对定位会提升元素的层级
开启绝对定位会使内联元素变成块元素, 宽度和高度默认被内容撑开
- fixed 固定定位
固定定位是绝对定位的一种, 不同点：
永远只相对于页面窗口进行定位
IE6及以下不支持固定定位
## 元素层级
如果元素层级相同, 则结构上在下面的元素会覆盖上面的
可以通过z-index来指定层级, 层级越高越优先显示
父元素层级再高也不会盖住子元素, 父元素调高层级, 子元素也会自动调高
## 透明
opacity
- 0-1之间的值, 0是完全透明
- IE8及以下不支持
filter: alpha(opacity=50)
- 在IE中使用此属性代替
- 0-100之间的值
## css2背景
background-color: 可以设置为透明transparent,从border-box绘制
background-image: url(相对路径或者绝对路径)
- 元素大小默认为位图的大小
- 如果背景图片大于img元素, 则从左上角开始显示, 多出部分不显示
- 如果背景图片小于img元素则默认平铺来充满元素
- 可以同时指定背景图片与背景颜色, 此时背景颜色会充当底色
- 在IE6中对PNG24支持不高, 如果使用则透明效果无法正常使用, 使用png8来解决或者引入外部js文件处理
background-repeat:
- repeat 默认值, 双向平铺
- no-repeat 不平铺
- repeat-x 水平平铺
- repeat-y 垂直方向平铺
可以通过平铺来将1像素宽或高的图片填充各种元素的背景
background-position:
进行img中的图片位置定位
- 使用left,top,right,bottom,center中的两个值来确定图片位置
如果只给出一个值第二值默认是center
- 指定偏移量
第一个值为水平偏移量第二值为垂直偏移量, 偏移量为百分比时, 是指元素大小减去图片大小的百分比, 保留正负号
background-attachment:
设置背景图片是否髓页面滚动
- scroll 默认值, 背景图片随窗口滚动
- fixed, 背景图片固定, 不随页面滚动
当设置成fixed时, 背景图片的定位会变成相对于视图调整, 不推荐使用性能不足, 使用img固定定位代替
background
设置所有背景相关的属性, 没有顺序与数量要求, 不设置的值会有默认值
## CSS-sprite
将多个图片整合成一个请求, 加快访问速度, 提升体验并且能够减少图片的总大小
## 条件hack
当只需要在某些浏览器中执行某些代码时使用
有些浏览器能识别而其他浏览器不能识别
适用于IE9及以下：
<!--[if IE]>
<![endif]-->
语法：
<!-- [if (keyword)? IE (version)?]>
<![endif]-->
## 属性hack
在样式前添加_, 只有IE6生效
添加*, 只有IE7及以下生效
## IE6双倍边距bug
在IE6中如果给左浮动元素设置左外边距或者给右浮动元素设置右外边距会变成双倍外边距
给此浮动元素设置成inline可以解决
# CSS2.1
## 包含块
在大多数浏览器, 初始包含块是一个视窗大小的矩形
- 对于浮动元素, 包含块是最近的块级祖先元素的内容边界构成
- 对于非根元素, position是relative或static, 包含块由最近的块级框的内容边界构成
- 对于非根元素, position是absolute, 包含块为最近的position不是static的祖先元素
如果祖先元素为块级元素, 包含块则为该元素的内边距边界
如果没有祖先, 元素包含块为初始包含块
left,top,bottom,right,width,height默认值为auto, 不可继承
margin, padding默认值为0, 不可继承
border-width默认值为medium
width, left,padding, margin的百分比是包含块的width的
height, top的百分比是包含块的height的
## 浮动
开启浮动时层数提升半层, 一个元素占两层, 第一层为盒模型, 第二层为文字, 此理论只在浮动有效
## 三列布局要求：
1.两边固定, 当中自适应
2.中间要完全显示
3.当中列要优先加载
绝对定位来三列布局
- 中间不能设置最小宽度, 不推荐
浮动来三列布局
- 中间页面会最后加载
圣杯布局
- 使用浮动搭建基本布局
- 调整左右的margin-left使其处于同一行
- 使用relative使左右处于中间页面的两端
## 前端社区
- segmentFault
- 掘金
- 奇舞周刊
## 素材网
- 17素材网
## 伪等高布局
- 给三列内容设置非常大的下内边距
- 给三列内容设置与下内边距相同的下外边距, 为负值, 使外部块元素大小与未设置下内边距时相同
- 给外部块元素设置溢出隐藏
## 双飞翼布局
- 与圣杯布局基本类似
- padding设置给中间div中嵌套的子div而不是给父div, 直接可以将中内容显示而不被左侧内容覆盖
## html与body的高度问题
- 需要视图html, body高度三合一时两者都必须设置height:100%, 没有设置html高度时, body高度都由内容撑开
- html或者body其中之一使用overflow:scroll时, 都是让document出现滚动条
- html和body都设置时, html的scroll设置给document, body的才设置给body
- 常被用来禁用系统默认滚动条, 代码为:
html, body{
height: 100%;
overflow: hidden;
}
- 当使用此方案使body具有overflow:scroll使body滚动条模拟视图滚动条时, 可以使用绝对定位模拟固定定位, 常用于移动端或解决IE6没有fixed的问题
使用caniuse.com网站来检查api兼容性
## stickyFooter
粘连布局
- 有一块内容`<main>`
- 当`<main>`的高度足够长时, `<footer>`跟在`<main>`的后面
- 当`<main>`元素比较短的时候, 我们希望`<footer>`能够“粘连”在底部
1.给wrap设置最小高度
2.给main设置相等于footer高度的下内边距, 为了不让footer遮挡住main里的文字,因为main高度是百分比所以视图中没有给footer占位的地方
3.给footer设置相等于自身高度的上外边距, 值为负
```javascript {line-numbers}
<div class="wrap">
<div class="main"></div>
</div>
<div class="footer"></div>
```
## box: CSS布局基本单位
元素类型与display的值决定了box的类型。不同的box会参与不同的Formatting context
box类型:
block-level box:
display属性为block, list-item, table的元素, 会生成block-level box, 并且参与block formatting context
inline-level box:
display属性为inline, inline-block, inline-table的元素, 会生成inline-lebel box并且参与inline formatting context
Formatting context是页面中一块渲染区域, 并且有一套渲染规则, 决定子元素如何定位以及和其他元素的关系和相互作用
BFC只有block-level box参与, 规定了内部的block-level box如何布局, 并且与这个区域外部毫不相干
BFC布局规则
1.内部box会在垂直方向, 一个接一个放置
2.BFC的区域不会与float box重叠
3.内部的box垂直方向距离由margin决定, 属于同一个BFC的两个相邻块级box的margin会发生重叠
- 两个方式来使其不重叠, 其一是使两个元素属于不同BFC, 其二是使两个元素不相邻
4.计算BFC高度时, 浮动元素也参与计算
5.BFC就是页面上的一个隔离的独立容器, 容器里面的子元素不会影响到外面的元素, 反之也是如此
出现BFC的情况
1.根元素
2.float属性不为none
3.postion为absolute或fixed
4.overflow不为visible
5.display为inline-block, table-cell, flex, inline-flex
## 多余内容出现省略号:
1.white-spacing: nowrap; 强制不换行
2.text-overflow: ellipsis; 决定如果对溢出文本应用样式
3.overflow: hidden;
4.display: block; 在有些情况下设置没宽度, 如果display为inline-block宽度会被内容撑开, 使多余部分不会出现省略号
## 清除浮动
1.给父元素设置高度, 扩展性差
给父元素设置成BFC, 在IE6,7中用开启haslayout解决
2.给父元素设置overflow:hidden, 移动端常用
3.给父元素设置定位
4.给父元素设置浮动
定位盒子或者浮动盒子的宽高会默认由内容撑开而其余的宽高默认为包含块的100%
5.空div标签清除浮动, 在IE6中可能会造成最小高度问题且违反结构行为样式分离原则
- 当给div设置高度时, 在IE6中最小只能设置成font-size的最小值12px, 但是即使将font-size设置成0时也依然会有2px的高度, 设置overflow: hidden才能解决
6.br标签用html属性clear来清除浮动,在IE6中无效且违反结构行为样式分离原则
7.伪元素清除浮动, 在IE6,7中不支持, 使用zoom解决, PC端常用
## haslayout
IE6,7特有的概念, 如果一个元素没有布局, 则它的尺寸和位置由最近拥有布局的祖先元素控制
IE团队是为了减少性能开销才将元素变成拥有布局和没有布局这两种情况
默认拥有布局的元素
html, body, table, tr, td, img, hr,
input, select, textarea, button,
iframe, embed, object, applet, marquee
触发haslayout
IE6或IE7支持
1.float为left或right
2.display为inline-block
3.position为absolute
4.width为除auto外的值
5.height为除auto外的值
6.zoom为除normal外的值
7.writing-mode为tb-rl
IE7支持
min-height:任意值
min-width:任意值
max-height: 除none外
max-width: 除none外
overflow, overflow-x, overflow-y: 除visible外任意值, 仅用于块元素
position: fixed
## 检测低版本IE
js中结合b标签的innerHTML与条件hack, 最后判断innerHTML内的标签是否存在来决定版本
function isIE(version){
var b = document.createElement("b");
b.innerHTML = "<!--[if IE "+version+"]><i></i><![endif]-->"
return b.getElementByTagname("i").length == 1;
}
## 垂直水平居中
已知高宽的水平居中
- 调整margin-left为负值
- 绝对定位盒子高度由内容撑开
水平方向上: left + right + margin + padding + width = 包含块的宽度
垂直方向上: top + bottom + margin + padding + height = 包含块的高度
因此可以将left,top,bottom,right设置为0再设置固定高宽
将margin设置为auto可以垂直水平居中
未设置高宽时默认高宽撑满父元素
未知高宽的水平居中
- 设置绝对定位, left和top设置为-50%
- 使用transform: translate3D(-50%, -50%, 0)
兼容性较差
## line-height
行高定义为两行字的基线间距离, 常用于单行文本垂直居中
内容区：顶线到底线间的距离
行内框：内容区加上 (行高-字体大小)/2 的值
行框：一行中最大的行内框的值
如果要处理大量文本, 建议把行高设置比字体大, 因为当行高比内容区小时, 上下缺少的高度渲染会根据不同浏览器进行变化
格式化css时一般会统一设置line-height为1, 即font-size的一倍, 纯数字为行高因子
行高因子继承时, 是行高因子, 其他的百分比, 像素等是继承计算值
## 垂直居中
vertical-align
用来指定inline-block的垂直
当给图片垂直居中时可以通过伪元素after设置一个内联块状元素来使与图片同一行的行内框撑满父元素
再给图片设置vertical-align: middle就能使图片垂直居中
# CSS3
样式表由规则组成
规则由选择器与声明块组成
声明由CSS属性与键值对组成
CSS选择器渲染是从右向左寻找
## 基本选择器：
1.通配符 *
2.id选择器 #
3.类选择器 .
4.后代选择器 空格
5.元素选择器 元素名
6.分组 ,(结合符)
## 基本选择器扩展：
1.子元素选择器 >
2.相邻兄弟选择器 +
3.通用兄弟选择器 ~
## 属性选择器
1.存在及值选择器
[attr] 选中存在attr属性的元素
[attr=val] 选中值为val的属性
[attr~=val] 选中值中以空格分隔时带有val属性的元素
2.子串值属性选择器
[attr|=val] 选中值为val或者以val-开头的元素
[attr^=val] 选中以val开头的元素
[attr$=val] 选中以val结尾的元素
[attr*=val] 选中值包含有val值的元素
## 伪类选择器
1.链接伪类 只能给链接标签a使用
:link
:visited 由于隐私问题, 这个伪类只能控制color, bg-color, border-color
:target 点击a元素, a元素的锚点充当id选择器来选中的某个元素, 锚点会在URL中显示出来
2.动态伪类
:hover
:active
3.表单伪类
:enable
:disable
:checked
:focus
4.结构性伪类
index从1开始
:nth-child(index)
例子： #wrap li:nth-child(1), 找到#wrap下第一个子元素且这个子元素必须为li
li:nth-child(1), 找到所有标签的第一个子元素且这个子元素必须为li
延伸
:first-child
:last-child
:nth-last-child
:only-child 相当于:first-child:last-child
:nth-of-type(index)
例子： #wrap li:nth-of-type(1), 找到#wrap下第一个li子元素
li:nth-of-type(1), 找到所有标签的第一个li子元素
重要问题：这个属性以元素为中心, 当父元素中有多个不同子元素, 此选择器可能同时选中不同元素
#wrap .inner:nth-of-type(1), 找到#wrap下相同元素中第一个类为inner的子元素而不是找到#wrap下第一个类为inner的子元素
延伸
:first-of-type
:last-of-type
:nth-last-of-type
:only-of-type 相当于:first-of-type:last-of-type
:empty
不能含有任何内容, 包括空格
5.伪元素选择器, 可以使用单冒号或者双冒号,位于dom树之外, 是由css进行创建
::after
::before
::firstletter 第一个字母
::firstline 第一行
::selection 光标选中的部分
## 声明的优先级
选择器特殊性, 特殊性为4个部分 0,0,0,0
ID选择器特殊性为第三位
类选择器, 伪元素, 属性选择器特殊性为第二位
伪类与元素特殊性为第一位
通配符不增加特殊性
结合符对特殊性没有贡献
内联中的选择器特殊性为第四位
继承属性没有特殊性
重要声明
添加在声明最后即分号之前
浏览器会将重要声明与非重要声明分为两组, 先解决每一组之间的冲突, 再解决两组之间的冲突, 胜出的一定重要声明
权重：
读者的重要声明
创作者的重要声明
创作者的正常声明
读者的正常声明
用户代理的声明
计算声明优先级：
按照来源排序
按照选择器特殊性排序
按照顺序排序
## 自定义字体与字体图标
CSS3提供, 不能放在声明块中
@font-face{
font-family: "字体名",
src: url(路径)
}
上传矢量图到icomoon转换成字体demo再根据demo修改自己的页面
由于字体图标属于font, 当想修改样式时通过修改font相关的样式来修改字体图标
## 新增UI样式
1.opacity
性能较visibility高, 不继承但是子元素会应用透明效果
2.rgba
第四个参数是设置opacity值, 可以省略0, 例子rgba(0,0,0,.5)
3.text-shadow
默认值为none, 不可继承
可选值：[(x偏移量, y偏移量, 模糊程度, 颜色)]{1,}
可以添加多层阴影
浮雕文字
字体设为白色, 使用字体阴影
模糊字体
使用text-shadow的第四个参数
模糊图片
使用浏览器过滤器filter: flur(10px)来对指定元素模糊(不是对元素背景)
4.transition
给元素添加指定时长的动画效果, 参数为s
5.direction
设置文字呈现方向
可选值：ltr, rtl等, 配合unicode-bidi:bidi-override
6.-webkit-text-stroke 非CSS3内容, 由浏览器自主实现
文字描边功能
-webkit-text-stroke: <length> <color>;
## 新增盒模型样式
1.box-shadow
默认值为none, 不可继承
可选值：[(inset/outset, x偏移量, y偏移量, 模糊程度, 模糊面积, 颜色)]{1,}
2.-webkit-box-reflict 非CSS3内容, 由浏览器自主实现
box倒影
可选值：
-webkit-box-reflict: <direction> <间距>; 第三个参数可以设置为渐变ilnear-gradient/radial-gradient
3.resize
控制块元素伸缩
常用可选值：vertical, horizontal, both
4.box-sizing
border-box 使盒模型在设置宽高时会自动调整内容区使宽高包括内边距与边框
content-box 默认值
## 新增UI样式
1.border-radius
默认值0, 不可继承
百分数水平参照于盒模型的宽度, 垂直参照盒模型高度, 最高值为50%, 超出将被设置为50%, 在IOS5或者安卓4之前不能使用, 尽量不要使用
可选值:
当没有/时, 内部画的圆按照参数不同分别按顺序应用于左上, 右上, 右下, 左下
radius
当有/时, 内部画的圆对于4个角来说X轴半径固定, Y轴半径按照参数不同分别按顺序应用于左上, 右上, 右下, 左下
(first radius)/radius
2.border-image-source
设置边框图片, 参数为url()
必须配合border-width与border-style使用, 但是border-style的效果不会生效只显示图片
配合border-image-slice来决定图片在边框的分布, 对图片按照上右下左的顺序根据设定值规定的距离进行切割再放置在边框上
例如border-image-slice:33.3333%,就是对这个图片距离上右下左33.3333%的地方切割放置在边框上, 当加上fill值时才将图片中心内容当做background-imgage给图填充否则不填充
浏览器会将切割好的部分平均分成三部分放置在边框角和边框上, 边框上的图片默认会被拉伸, 由border-image-repeat的值决定
border-image-repeat：
1.repeat, 边框上的部分从边框中心开始平铺, 两边可能会被截断
2.round, 平铺图像。当不能整数次平铺时, 根据情况放大或缩小图像。
3.stretch, 拉伸
4.space, 平铺图像 。当不能整数次平铺时, 会用空白间隙填充在图像周围（不会放大或缩小图像）
3.border-iamge-outset
使边框图片向外扩张, 不能为负值
4.CSS3背景样式
1.background-origin
决定背景从哪里开始绘制,在没设置no-repeat或者clip的情况下其余部分会被平铺占满
border-box
padding-box,为默认值
content-box
2.background-clip
决定背景从哪里剪去
border-box,为默认值
padding-box
content-box
3.background-size：
修改图片大小
默认为auto
- 固定值, px, em, xm等
- 百分比, 背景盒模型的百分比, 根据background-origin值决定
- contain 使图片在不改变比例的情况下全部被父元素包含
-cover 使图片在不改变比例的情况下将父元素填充满
5.线性渐变(应用给background-image)
background-image: linear-gradient(toright, red,yello,green);(颜色参数可以是rgba进行透明度渐变)
第一个值可以是角度N deg, 正上方为0, 顺时针为正, 逆时针为负
从第二个颜色参数起在每个颜色后可以添加百分比或者固定值表示在这个值后的颜色就是自己写定的颜色, 第一个颜色参数是指这个值前的颜色是自己写定的颜色
background-image: repeating-linear-gradient(toright, red 100px,yello 200px);
从第100px开始以red开头渐变, 渐变到300px以yello结束, 剩余像素采用平铺的方式
6.径向渐变
background-image: radial-gradient([closest-side|farthest-side|closest-corner|farthest-corner][circle|ellipse][at 渐变圆心X轴的位置, 渐变圆心Y轴的位置], red,yello,green);(第一个参数默认为farthest-corner ellipse)
## 过渡
transition
存在简写形式, 可以使CSS在可动画化属性发生变化的过程时按照指定时间内产生渐变动画
给元素增加此属性后即便是js改变的属性也会发生动画
-transition-property
默认值为all, 指定需要产生动画效果的属性, 可以指定多个属性
-transition-duration
指定动画过程的时间, 单位可以是s与ms, 默认为0s, 不接受负值, 必须加单位
可以指定多个参数, 当此参数数量少于指定的属性时, 整个时长列表会重复放置
-transition-timing-function
ease 先快后慢, 默认值
linear 线性
ease-in 加速
ease-out 减速
ease-in-out 先加速后减速, 速度比ease快
cubic-bezier 贝塞尔曲线
steps(num, [start|end]) 默认为end, start意思为触发此状态时立刻前进一步状态, end指触发此状态后等待一个间隔再前进一步状态
可以有多个参数, 当参数数量少于property时, 不足的部分使用默认值
-transition-delay
表示延迟时间, 规则与duration一致
过渡完成事件
-transitioned, 只能在dom2事件中触发(addEventListener)
transition难点1：
css属性存储在内存中会快于浏览器渲染
transition难点2：
transition在首次渲染未结束前是不会触发的
-css渲染慢于同步下的js引擎, 此时会导致许多可能的预期外影响
在js中直接设置元素样式, 此时不会触发动画
在js中先设置alert()后设置元素样式, 会触发动画, 因为alert的异步特点
在js中将样式写在onload的事件函数中会触发动画
在js中将两个不同样式同步地写在onload事件函数中只会触发第二个样式的动画
使用settimeout等待css渲染完后才可以触发动画
先修改样式再添加duration仍然会触发动画
transition简写
严格遵循书写顺序, 按照duration, property,timing-function,delay的顺序书写
可以用逗号分隔不同的动画效果, 在遇到第一个可以解析为时间的值时会赋值给duration
## 2D变换
transform 只支持块级元素
rotate 旋转, 单位为deg
translate 平移, 可设置单值, 与X轴平移相同
translateX
translateY
skew 倾斜, 单位为deg, 可设置单值, 与X轴倾斜相同
skewX
skewY
scale 缩放, 可设置单值, 使X轴与Y轴按同比例缩放
scaleX
scaleY
基点的变换
transform-origin 设置X轴Y轴上的基点位置, 百分比是基于元素的宽高
对除translate外的属性才产生影响
2D变换中所有的变换都是基于矩阵运算
变换组合
在变换组合时矩阵运算方式是从右向左的, 感官上可认为坐标系按照从左向右的顺序发生了变换
transition难点3:
在绝大多数变换组合进行切换时, 如果两次变换的数量, 顺序不同时, 不会触发过渡动画
因此在涉及到变换组合内的变换改变的时候要注意数量和顺序问题
transition难点4:
过渡变换只关注变换起始状态与最终状态, 无法控制中间状态
## 3D变换
景深
perspective
景深可以理解为肉眼距离显示屏的距离, 景深越大, 变换效果越不明显
可以使3D效果产生近大远小的功能, 不可继承, 但是效果是作用给后代元素
transform: perspective
写在需要作用的元素中, 但必须放在tranform所有变换的首位, 其他位置会使变换失效
灭点
控制视图的焦点即景深
景深越大灭点越远, 元素变形更小
景深基点
perspective-origin(x, y, z)
控制视角的位置, 默认值为50% 50% 50%, 参照border-box模型, 常与perspective结合使用
transform-style
preserve-3D, 常用值
none, 默认值
营造有层级的3d舞台, 不可继承属性, 但只作用于子元素
景深叠加
祖先元素增加多个景深会产生景深叠加, 由于叠加规则不可控因此要避免
backface-visibility
-visible
-hidden
隐藏背面
rotate3D(x,y,z,angle), x, y, z的值只有0,1的区别, 大于1没有影响
rotateX()
rotateY()
rotateZ()
translateD(translateX,translateY,translateY)
scaleZ()
单独使用时没有意义, 组合使用会影响到Z坐标轴
难点：
当对某个元素进行变换时, 这个元素结构内部的所有元素都会发生变换, 而不仅仅只有设置了变换的这个元素会产生变换效果
## 动画
动画内属性
animation-name
- 指定关键帧的名字
关键帧基本写法：
@keyframes name{
from{}
to{}
}
animation-duration
- 指定动画周期, 无单位与负值无效
animation-timing-function
- 指定关键帧周期的运动方式
- steps(step, end默认值|start)
设置end时动画的起始位置会占用一步, 否则不会, 即start看不见第一帧, end看不见最后一帧
animation-direction
- 反转关键帧执行顺序, 使顺序为to-from, 同时也反转动画运动方式, 即timing-function
- normal 默认值
- reverse 反转
- alternate 播放顺序为from-to然后to-from然后循环
- alternate-reverse 播放顺序与alternate相反
动画外属性
animation-delay
- 指定延迟时间
animation-literation-count
- 只影响动画内的属性
- infinite 无限次数
- num
animation-fill-mode
- 管理元素在动画外的状态
-none 默认值, 动画外的属性保持在动画之前
- backwords from之前的状态保持的和from的状态保持一致
- forwords to之后的状态与to的状态保持一致
- both 包含以上两种情况
animation-play-state
- 控制动画是否暂停或运动
- paused
- running 默认值
关键帧进阶：
@keyframes name{
from(0%){
}
百分比{
}
百分比{
}
百分比{
}
to(100%){
}
}
百分比为duration时间的百分比, 整个关键帧中的百分比为一个动画周期, 两个百分比算作一个关键帧周期
简写属性
animation
与transition类似, 前两个能被解析成时间的参数被看做duration与delay
## flex布局
常用于移动端
安卓4.3及之前版本使用需要-webkit-flex
更老的版本使用flex的老版本称为box, 使用时加上-webkit-前置
用法：
display: flex|-webkit-flex|-webkit-box
flex布局分为主轴与侧轴, 放下为向右与向下, 整体又分为容器与项目, 容器属性作用于容器, 项目属性作用于项目
表格中没有写属性的表示老版本不存在此属性
| |老版本box|新版flex|
|:---:|:---:|:---:|
| 容器 |||
|决定主轴或侧轴水平或者垂直 | `-webkit-box-orient: vertical|horizontal ` |`flex-direction: column|row`|
|决定主轴的方向 | `-webkit-direction: normal默认值|reverse` | `flex-direction: column-reverse|row-reverse`|
| 主轴富裕空间管理 | `-webkit-box-pack:start|end|center|justify` | `justify-content: flex-start默认值|flex-end|center|space-between|space-around`|
| 侧轴富裕空间管理, 单行/单列有效 | `-webkit-box-align:start|end|center|justify` | `align-items: flex-start默认值|flex-end|center|baseline|stretch`|
| 控制侧轴的堆砌方向 | | `flex-wrap: nowrap默认值|wrap|wrap-reverse`|
| 控制多行/多列的富裕空间管理 | | `align-content(把每行/列看成一个整体): flex-start|flex-end|center|space-between|space-around|stretch|normal默认值`|
| 新版本中flex-direction与flex-wrap的简写 | |`flex-flow: column|row|column-reverse|row-reverse [nowrap默认值|wrap|wrap-reverse]`|
老版本：
start 表示富裕空间在右边(x轴)或下边(y轴)
end 表示富裕空间在左边(x轴)或上边(y轴)
center 表示富裕空间在两边
justify 表示富裕空间在项目之间
老版本不能控制侧轴方向, 因为老版本无法在侧轴堆砌, 想要在侧轴有堆砌效果必须使用多个容器
新版本：
flex-start 表示富裕空间在按轴方向的后面
flex-end 表示富裕空间在按轴方向的前面
center 表示富裕空间在两边
space-between 表示富裕空间在项目之间
space-around 表示富裕空间在项目两边
baseline 基线对齐
stretch 等长/高布局, 项目不能有高度
align-content中的stretch 侧轴的等长/高布局, 富裕空间会按照1:1的比例填充给每一个项目
老版本box 新版flex
项目：
弹性空间管理, 放大 -webki-box-flex: 默认值为0 flex-grow: 弹性因子默认值为0
将主轴上的富裕空间按照设定的比例分配个每个项目上, 参数为纯数字
计算规则
可用空间 = 容器大小 - 所有相邻项目的flex-basis总和(没有设置时默认为height(y轴), width(x轴))
可扩展空间 = (可用空间) / 所有相邻项目的flex-grow的总和
每个项目伸长后大小 = 每个项目自身的flex-basis(没有设置时默认为height(y轴), width(x轴)) + 可扩展空间 * 每个项目自身的flex-grow
在老版本中没有flex-basis因此此值就是每个项目自己的width/height
老版本可以控制伸缩, 伸缩的计算规则都与新版本的flex-grow相同
弹性空间管理, 缩小 flex-shrink 收缩因子默认值为1
计算规则
需缩减大小 = 容器大小 - 所有相邻项目的flex-basis总和(没有设置时默认为height(y轴), width(x轴))
总权重 = 每一个项目flex-basis * flex-shrink之后求和
每个项目的权重 = 每一个项目flex-basis * flex-shrink/总权重
每个项目缩减后大小 = 每一个项目flex-basis - 需缩减大小 * 每个项目的权重
在flex-wrap值不是nowrap时, 此属性失效
flex-grow与flex-shrink在计算时的区别在于后者要将flex-basis考虑进权重
排列顺序 order
决定每一个项目在容器中排列的顺序
管理单个项目的富裕空间, 单行/单列有效 align-self: flex-start|flex-end|center|space-between|space-around|stretch|auto默认值
如果此项目没有父元素即容器时, 默认为stretch
基值 flex-basis 默认值为height(y轴), width(x轴)
flex练习: flexboxfroggy.com
flex应用
1.等分布局
flex-basis: 0
flex-grow: 1
flex-shrink: 1
简写属性
flex: 1
等同于上面三行代码
## 响应式布局核心
CSS2媒体查询
<link rel="stylesheet" type="text/css" href="index.css" media="print|screen"/>
指定媒体才引入相应css代码
CSS3媒体查询
@media 媒体类型 [and 媒体属性]{0,} {
}
对声明特殊性没有任何贡献
媒体类型：
screen|print|all(默认值)
媒体属性：
width 可添加min或max前缀, 当为min时表示大于某个值有效
height 可添加min或max前缀, 当为max时表示小于某个值有效
device-width 表示移动端：设备独立像素, pc端：分辨率。可添加min或max前缀
device-pixel-ratio PC端值为1, 移动端与手机种类有关, 使用时添加webkit前缀, 还可添加min或max前缀
orientation 指定显示的屏幕, portrait表示竖屏, landscape表示横屏
关键字：
and 代表与, 一般用来连接媒体类型与媒体属性
only 和浏览器有关, 老版本不支持媒体属性, 因此添加后会使老浏览器无法识别而不执行这段查询, 写在媒体查询开头
逗号, 代表或的意思, 逗号前为一组规则, 后为一组规则, 可以有3组及以上规则
not 位置与only相同, 同样在老浏览器中无法识别
多列布局
column-width 指定一列宽度, 由于文字间隔等原因一般会比width/(column-width)的列数少1
column-count 分成指定列数
column-gap 指定两列之间间距
column-rule 指定每列间的分隔线样式
# 规范
ECMA262 JS基础规范
DOM0 浏览器厂商自主实现, 非W3C规范
DOM1 开始成为W3C规范, 专注于html与XML文档
DOM2 增加了样式表对象模型, addEventListener等
DOM3 对DOM2增加了内容模型(DTD,schemas)和文档验证 | {

结构
<html>
<head>
<title></title>
</head>
<body></body>
</html>
title标签中的内容影响网站在搜索引擎中的排名
注释
<!-- -->
标签
例：
`<font color="" size=""></font>` //不推荐使用
属性写在标签的头部
页面声明
doctype
浏览器存在两种模式:标准模式与怪异模式
如果不写页面声明,有些浏览器会进入怪异模式,导致页面无法正常工作
如果想定义页面为HTML5标准进行如下声明:
`<!DOCTYPE html>`
实体(转义字符串)
空格
大于号 >
小于号 <
常用标签
img
拥有以下属性:
src:
alt:
width:
height:
当只设置width或者height时,图片大小会按照比例缩放
如果不打算制作自适应的网页,最好不要使用这个标签的width和height属性,因为即便缩小图片的大小,仍旧会占用图片原大小的内存
meta
1.设置网页关键字
`<meta name="keywords" content=""/>`
2.设置网页描述
`<meta name="description" content=""/>`
3.设置网页重定向
`<meta http-equiv="refresh" content="...(时间),url=...(网址)"/>`
4.设置字体
`<meta charset="UTF-8"/>`
图片格式
jpeg:
支持颜色较多,不支持透明动态,常用于照片
gif:
支持颜色少,支持简单透明与动态
png:
支持颜色多,支持透明,不支持动态
使用规则:
效果一致使用小的
效果不一致使用效果好的
内联框架
`<iframe></iframe>`
属性：
src:
可以使用相对路径与绝对路径
height：
width：
name：
指定name名
不推荐使用，内联内容不会被搜索引擎检索到
框架集
`<frameset></frameset>`
内部使用`<frame></frame>`引入外部页面
属性:
rows 指定框架集中的页面一行一行的排列
cols 一列一列的排列
必须指定属性值来表示frame在页面中的占比
框架集可以嵌套，会充当一个frame
`<a></a>`
属性:
href:
可以使用相对路径或绝对路径，如果地址不确定可以使用#占位，会自动跳转到当前页面的顶部
使用#id可以跳转到指定id的元素的所在位置
使用mailto:(收件人地址)可以打开电子邮件客户端并将收件人设置为指定的收件人地址
target:
指定打开链接的位置
--self 在当前窗口打开，默认值
--blank 在新窗口打开
内联框架name值，可以在指定框架中打开
`<center></center>`
居中元素，不推荐使用
标签的title属性: 当鼠标移入时显示的内容
文本标签
语义表示强调 没有语义
`<strong></strong>` 粗体 `<i></i>`
`<em></em>` 斜体 `<b></b>`
表示细则
`<small></small>` 缩小字号
表示引用，可用在所有有书名号时
`<cite></cite>` 斜体
短引用,浏览器会默认给标签里的内容添加引号
`<q></q>`
长引用,块级引用，是块元素
`<blockquote></blockquote>`
上标
`<sup></sup>`
下标
`<sub></sub>`
带有删除划线的内容
`<del></del>`
带有下划线的内容
`<ins></ins>`
保存html代码中的格式
`<pre></pre>`
表示这是代码的语义
`<code></code>`
列表标签
列表之间可以互相嵌套
1.无序列表
使用ul创建无序列表，使用li表示列表项，默认的项目符号由于不同浏览器显示不同不使用，如果需要设置图片
2.有序列表
使用ol创建，使用li表示列表项
3.定义列表
使用dl创建定义列表，dl中有两个子标签
dt: 被定义的内容
dd: 对定义内容的描述
dl，ul，ol之间可以相互嵌套
表格
使用table创建表格
使用tr创建一行
在tr中使用td创建单元格
表格创建时默认没有边框，可以通过修改table样式修改样式
在td中使用colspan属性，值为需要合并的单元格数量，来横向合并单元格
使用rowspan来纵向合并
- table是块元素，在table和td间默认有个border-spacing属性来调整边框距离
- 有border-collapse: collapse来对表格边框进行合并，如果设置了边框合并，border-spacing属性自动失效
- 可以使用th来表示表格表头，与td效果相同只是会有一些默认字体效果
长表格
在一些情况下非常长就需要将表格分为表头，表格主体，表格底部三部分
使用thead，tbody，tfoot来区分table的不同部分，它们是table子标签，tr需要写在这些标签中
无论这三个属性写在table的什么地方，thead永远显示在头部，tfoot永远显示在底部
如果表格中没有写tbody，浏览器会默认添加tbody，所以tr不是table的子元素
表格布局
以前经常使用表格来布局，现在被css替代了，因为维护困难且难以被搜索引擎检索
布局特性：
- 表格列数由最多的td或th决定
- table可以嵌套
表单
将用户输入提交给服务器
使用form创建表单，必须指定action属性，值为表单提交的地址
使用label来框中文字，给label指定for属性，值为需要连接的表单项的id，点击label相当于选择对应的表单项
使用input指定表单项，在表单项中指定name属性的才会真正提交，指定placeholder属性会有提示水印，在IE8及以下不支持，需要JS
- type="text" 单行文本框
- type="password" 密码框
- type="submit" 提交按钮
提交按钮中用value值能改变按钮的文字
- type="reset" 将表单内容恢复成默认值
- type="button" 创建单纯的按钮
- type="radio" 单选按钮
通过name属性分组，相同的为一组，用来选择的表单项都需要指定value属性，提交给服务器的是value值
- type="checkbox" 多选按钮
通过name分组
使用button标签来创建按钮更灵活，推荐使用，使用属性cursor设置移上去鼠标样式
使用select创建下拉列表
可以添加multiple="multiple"使其变成可以选中多个
在之中使用option来创建下拉项，name给select指定，value给option指定
使用optgroup对多个option进行分组，通过label属性对一组option创建组名
使用textarea创建多行文本域
- resize: none; 不能调整框大小
在单选或者多选中使用checked="checked"来使其默认选中
在下拉列表中使用selected="selected"使其默认显示
使用fieldset创建表单分组，会有边框将一组内容框中(针对所有表单元素)
在fieldset中使用legend为每一组创建组名，组名显示在边框的左上角中

# attribute与property
## attribute属性
* HTML中的预定义与自定义属性, 在js中被一个叫做attributes的property所维护
## property属性
* JS原生对象的直接属性
## 两者间的转换关系
### 对非布尔值属性而言
* 实时同步
### 对布尔值属性而言
* property永远不会同步attribute
#### 没有修改过property时
* attribute会同步property
#### 修改过property时
* attribute不会再同步property
* 在浏览器中被识别的和用户所操作的都是property
# H5中的一些小功能
## class
* 由于class是关键字因此JS可以通过className属性来访问标签的class值
* 直接使用className来添加删除class不够方便, H5新增了classlist对象属性
* classlist是个伪数组, 其中有add, remove, toggle方法来增删class
## 自定义属性
* 在H4中只能通过setAttribute方法来修改自定义HTML属性
* 在H5中新增dataset对象来保存自定义的HTML属性
* 想要将自定义属性添加到dataset对象时需要以data-开头, 自定义HTML属性使用-分隔单词(`data-my-test`)
* 在dataset对象中, 自定义HTML属性以驼峰命名法表示(`myTest`)
## 文本可编辑
* 新增HTML属性contentEditable, 值必须为true否则无法开启
## HTML解析器相关
* 这些方法的兼容性都非常高
* 每次调用都会需要创建与销毁html解析器，虽然性能比用js直接创建节点要快，但是尽可能减少直接操作这些属性的可能性
* innerHTML
* 返回内部html代码
* outerHTML
* 返回包括当前节点的html字符串
* 给这个属性赋值等同于使用replace
* insertAdjacentHTML()
* 接收两个参数，第一个参数值是字符串，beforebegin，afterbegegin，beforeend，afterend，第二个参数是需要被插入的html字符串
# HTML5
* HTML5是定义HTML标准的最新版本, 表示两种概念
* 它是一个新版本的HTML语言, 具有新的元素, 属性和行为
* 它有个更大的技术集, 允许更多样化和强大的网站和应用程序
## H5优势
* 跨平台
* 快速迭代
* 降低成本
* 导流入口多
* 分发效率高
## H4与H5的差别
1. DOCTYPE, 或者称为Document type declaration, 文档类型声明, 缩写为DTD
2. document.combatMode 返回浏览器的渲染模式
* css1Combat 标准模式
* css1Combat 近似标准模式
* backCombat 怪异模式
3. 在IE9以上或者其他浏览器在三种渲染模式中几乎没有区别
4. 在IE7,8,9中理论上存在怪异模式，但实际只有标准模式
5. 在IE6中怪异模式与标准模式区别最大
6. 在IE5中只有怪异模式
7. html与head标签中HTML5内嵌了H4的许多属性
8. head中的meta标签指定了http的头消息
## 语义化标签
1. hgroup 包裹多个h1，h2...等
2. nav 导航栏
3. header 表示标题栏, 如果hgroup能够表现语义可以不使用
4. section 单独的模块
5. footer 脚注
6. article 单独的文章
7. aside 文章附属内容
## canvas
* 可以使用闭合和成对标签，不推荐使用闭合标签
* canvas是HTML5新增的元素，可以使用js脚本来绘制图片，最早由apple引入webkit
* 默认width为300，height为150，背景颜色默认继承
* 不能使用css来为canvas设置高宽，否则会在绘制时出错，会被拉伸
* 在canvas标签中添加内容可以使这些内容在浏览器不支持canvas时显示
* 获取canvas节点后只有width, height属性, getContext,isPointInPath,toDataURL方法可以使用
* 获取渲染上下文
```javascript
var canvasNode = document.querySelector('canvas') //此api只能获取当前页面的快照节点
if(canvasNode.getContext){ //检查兼容性
context = canvasNode.getContext('2d') //只有一个参数为2d，3d图形需要webGL
}
```
### 绘制矩形
#### 同步绘制, 所得即所见
#### canvas的基本图形为矩形，只调用一个api只能绘制一个矩形
* 绘制实心矩形`context.fillRect(x轴, y轴，宽，高)`
* 绘制空心矩形`context.strokeRect(x轴, y轴，宽，高)`
* canvas在实现绘制空心矩形时会在指定位置的上下/左右各绘制0.5px的边框，但是浏览器渲染时会向上取整实际成为2px的边框。
* 如果只想要绘制1px边框需要给x轴与y轴的实际位置多0.5
* 若想在距离画布左或上100px的位置绘制图形，则`context.strokeRect(100.5, 100.5，100，100)`
* 绘制实心的透明矩形`context.clearRect(x轴, y轴，宽，高)`
* 设置实心矩形的颜色`context.fillStyle = string` 可以使用rgba
* 设置空心矩形的边框颜色`context.strokeStyle = string` 可以使用rgba
* 设置空心矩形的边框宽度`context.lineWidth = number`, 会给边框的左右/上下同时设置为lineWidth一半的值, 参数不可为负值
* 设置两条线交汇时的形状`context.lineJoin = string`, 参数为miter(默认)，round(圆角)，bevel(斜角)
#### canvas的基本元素为路径
* 绘制直线
* beginPath() //清除路径容器中的内容
* moveTo(x, y) //将画笔抬起移至指定路径
* lineTo(x, y) //将路径从上一个位置平移至指定路径
* closePath() //使路径自动形成闭环
* stroke() //按照路径绘制直线, 绘制规则同strokeRect不会自动执行closePath
* fill() //按照路径自动填充内部, 会自动执行closePath
* rect(x, y, width, height) //创建一个矩形路径
* lineCap=butt(默认值)| round(圆角) | square(矩形) //指定线段的两端样式, 除第一种参数外都会增加线段的长度
* 绘制圆形
* `arc(x, y, radius, start, end)` 起始位置为画布x轴, end与start只能是弧度, 绘制方向为顺时针
* `arcTo(x1, y1, x2, y2, radius)` 需要先用moveTo指定一个起始点，再加上参数中两个点来表示一个角的路径, 最后用半径为radius的圆去与这个角相切得到的路径即为绘制后的结果
* `quadraticCurveTo(x1, y1, x2, y2)` 开始点与arcTo相同, 参数用来指定二次贝塞尔曲线的控制点与结束点
* `bezierCurveTo(x1, y1, x2, y2， x3, y3)` 三次贝塞尔曲线，前两种参数指定两个控制点位置，最后一种参数指定结束点的位置
#### save()与restore()
* 路径容器
* 堆结构
* 每次调用路径api时会向路径容器添加路径信息
* 调用beginPath时清空
* 样式容器
* 堆结构
* 每次调用样式api时在样式容器中覆盖原样式
* 调用save()时向样式堆压栈, 没有调用过样式api时保存的是初始化样式
* 样式栈
* 栈结构
* 调用restore()时会弹栈，并且将弹出栈的样式应用给样式容器
* 样式栈中会保存样式属性与变换位置
```javascript
//使用canvas的标准格式
context.save() //压入样式栈, 保存的是初始化样式
context.strokeStyle('pink') //覆盖样式容器
context.beginPath() //清空路径容器
context.stroke() //绘制
context.restore() //弹出样式栈
context.save() //压入样式栈, 保存的是初始化样式
context.strokeStyle('green') //覆盖样式容器
context.beginPath() //清空路径容器
context.stroke() //绘制
context.restore() //弹出样式栈
```
#### canvas变换
##### canvas中的变换都为累加操作, 不会覆盖
##### 整个canvas公用一个原点
* tanslate(x, y)
* 移动画布的坐标轴原点
* rotate(arc)
* 旋转画布的坐标轴
* 参数为弧度
* scale(x, y)
* 放大缩小画布中像素所占面积
* x和y控制在画布中的1像素的长宽实际在画布中占用的像素大小, 例如scale(2, 2), 画布中设定的1像素长宽会变为2像素
* 需要注意在css中的像素是一个抽象概念, 面积可以变大缩小, 默认1像素就是长宽为1像素的大小
### 使用图片
* drawImg(img, x, y, width, height)
* 使用图片与渐变应用给canvas, 需要将返回值赋值给fillStyle才会生效
* createPattern(img, [repeat|no-repeat|repeat-x|repeat-y])
* `createLinearGradient(x1, y1, x2, y2)` 指定渐变方向
* `gradient.addColorStop(0, 'red')` 添加渐变颜色，gradient是createLinearGradient的返回值
* `createRadialGradient(x1, y1, radius1, x2, y2, radius2)` 指定渐变方向
* `gradient.addColorStop(0, 'red')` 添加渐变颜色，gradient是createRadialGradient的返回值
### 绘制文本
* `fillText(text, x, y)`绘制字体
* `font='size family'` 大小字体缺一不可
* `strokeText(text, x, y)`绘制字体边框
* `textAlign = 'center|left|right'`决定字体与x, y原点的关系
* `textBaseline = 'middle|top|bottom'` 决定字体与基线的关系
* `measureText()` 返回字体在画布上的宽度
* `shadowOffsetX = float`
* `shadowOffsetY = float`
* `shadowBlur = float`
* `shadowColor = color`
* canvas的字体垂直水平居中
```javascript
ct.font = '60px sans-serif'
ct.fillText('aaa', 0, 0)
var a = ct.measureText('aaa')
ct.fillText('aaa', canvas.width/2 - a/2, canvas.height/2 - 60/2)
```
### 像素操作
* getImageData(x1, y1, x2, y2) 获取指定范围内的像素数据，返回值为imageData
* imageData
* width 水平方向上的像素数量
* height 垂直方向上的像素数量
* data 数组，每一个像素点的rgba的数据
* putImageData(imageData, x, y) 将指定像素数据绘制到canvas上
* createImageData(x, y) 创建一块像素信息
### canvas合成
* 全局透明度 globalAlpha = value 设置整个画布的透明度
* globalCompositeOperation source源指新图片，destination指老图片
* source-over 使源置于目标之上
* source-in 只显示源与目标重叠的源那部分
* source-out 只显示源与目标没有重叠的源那部分
* source-atop 在source-over基础上不显示源超出目标的那部分
* destination-over 使目标置于源之上
* destination-in 只显示目标与源重叠的目标那部分
* destination-out 只显示目标与源没有重叠的目标那部分
* destination-atop 在destination-over的基础上不显示目标超出的那部分
## 音视频
|主流视频文件格式|主流音频文件格式|
|---|---|
|MPEG-4 通常以.mp4格式命名|MPEG-3 通常以.mp3格式命名|
|FLASH视频 通常以.flv命名|aac音频 .aac|
|OGG 通常以.ogv格式命名|ogg音频 通常以.ogg格式命名|
|webM 通常以.webm格式命名||
|音视频交错 通常以.avi格式命名||
### 编解码器
|视频解码器|音频解码器|
|---|---|
|H.264|AAC|
|VP8|MPEG-3|
|Ogg Theora|Ogg vorbis|
制作视频的流程
* 制作一个ogg容器，使用Theora视频与Vorbis音频版本
* 制作webM容器，使用VP8视频和vorbis音频版本
* 制作MP4容器，使用H.264基本配置和ACC低配的音频
* 连接上述3个文件到同一个video, 向前兼容制作flash版本

## 视频与canvas结合
1. 获取video
2. 将video的内容用drawImage画到画布上
3. 播放视频时使用定时器按照定时器规定的帧数重绘画布
4. 使用loadeddata事件可以使视频加载完成后再执行
## 状态标签
* meter 创建类似于电池电量的进度条, 最多有三种颜色显示
* value 指定初始值
* min 指定最小值
* max 指定最大值
* low 指定区间下界
* high 指定区间上界，两者都写时可以将meter分为3个部分
* optimum 指定最优区间, 值可以为想要指定区间中的任意值
* progress 创建进度条
* value 指定初始值
* max 指定最大值
## 表单标签
* datalist 创建H5下拉菜单
* 使其的id值与input标签的list属性的值相同
* 在datalist中添加多个option标签，包含value属性
* 可以使input增加下拉选项
```html
<input type="text" list="test" value="test" />
<datalist id="test">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
</datalist>
```
* details 创建H5折叠菜单
* 内部第一个标签为summary, 此标签内的内容为默认可点击处的内容
* 使用p标签来填充折叠的内容
* 有布尔值属性open来指定默认开启
```HTML
<details>
<summary>aaaa</summary>
<p>bbbb</p>
<p>bbbb</p>
<p>bbbb</p>
</details>
```
## 注释标签
* ruby 指定需要添加注音的文字
* rt 添加的注音，会显示在ruby标签中的内容的顶上
## 标记标签
* mark 效果类似于span, 默认背景为黄色
## 表单标签
### type类型
* email 会检查有无@
* tel 移动端会弹出数字键盘
* url
* search 在输入框中增加可点击清空的按钮
* range 滑块
* min
* max
* step 控制一步的长度
* number 只能输入数字
* color 颜色选择器
* datetime 移动端使用，显示完整日期
* datetime-local pc端使用，显示完整日期
* time 显示时间不包含时区
* date 显示日期
* month 显示月份
* week 显示周
### 表单属性
* placeholder
* 选中::-webkit-input-placeholder
* autofocus
* 自动获取聚焦，当有多个时只生效第一个
* required
* 必填项
* pattern
* 设定正则表达式
* formaction
* 指定上传的表单地址
* list
* 值必须为datalist的id值
### 表单验证
* invalid事件
* 当表单验证不通过时触发
* setCustomValidity
* 自定义验证内容
* validity对象
* 是表单节点下的对象，内部包含8个属性，true表示已触发的验证
* valueMissing
* typeMismatch
* patternMismatch
* customError 当自定义验证触发时为true
## 跨文档传输
* 在H5中可以通过postMessage这个api在不同域之间进行消息传递，对于XDM来说，能够跨域的只有iframe与由当前页面弹出的页面
* postMessage(msg, domain)
* 第一个参数是想要传递的数据，为了兼容性最好只是字符串，想要传递对象时使用JSON代替
* 第二个参数为表示消息的接收方来自于哪个域，当参数为\*时可以传递给任何域的文档但不推荐
* 接收到XDM消息时会触发文档中window对象的message事件, 这个事件以异步的方式传递因此从发送到接收存在延迟, onmessage的事件对象有以下三个属性
* data
* 接收到的数据
* source
* 发送数据的域的window代理，只能使用其中的postMessage方法来向其发送回复
* origin
* 发送数据的域的字符串
## 原生拖拽
* 对于IE10及以上还有其他浏览器对目前的原生拖拽功能大部分已经支持
* 默认情况下图像，链接和文本是可以拖拽的，其他元素可以拖拽，但是可以通过给这些元素设置draggable为true来启动它们的拖拽功能
* 当一个元素进入拖拽状态直到被释放的时候会依次触发下列三个事件:
1. dragstart 拖拽开始
2. drag 拖拽中
3. dragend 拖拽结束
* 当一个元素成为放置元素，即拖拽元素移入它内部时会依次触发下列事件:
1. dragenter 被拖拽元素进入放置元素时
2. dragover 被拖拽元素在放置元素内移动时
3. drop/dragleave 被拖拽元素被丢入放置元素中或者移出放置元素
* 在所有拖拽事件被触发时，它们的事件对象会出现dataTransfer属性
* dataTransfer包含下列方法与属性
* setData(type, str)
* type在IE老版本中是text或者URL字符串，在H5规范中可以是所有MIME类型，考虑到兼容性text会被映射成text/plain，URL会被映射成text/url-list
* str是一个需要保存的字符串
* 此api可以为每一种MIME类型保存一个字符串但会在drag相关事件结束时全部销毁
* getData(type)
* 是一个需要提取的字符串类型，text或者URL，规则同setData的type属性
* dropEffect
* 用来表示拖拽元素目前能够执行的放置行为，只能在dragenter事件触发时设置，具有以下值:
* none 不要触发任何行为
* move 要触发移动行为
* copy 要触发复制行为
* link 要触发打开链接的行为
* 以上任何值都能决定拖拽元素被移动到放置元素时光标显示的样子
* effectAllowed
* 用来表示拖拽元素允许触发的放置行为，只能在dragstart事件触发时设置, 具有以下值:
* uninitialized 没有给拖拽元素设置任何放置行为
* none 不允许触发任何放置行为
* copy 允许触发复制行为
* link 允许触发打开链接的行为
* move 允许触发移动行为
* copyLink 允许触发复制与打开链接的行为
* copyMove 允许触发复制与移动的行为
* linkMove 允许触发打开链接与移动的行为
* all 允许触发任何行为
* setDragImage(ele, x, y)
* 指定一副图像变成拖动时产生的副本样子
* ele可以是元素也可以是图像，如果是普通元素则显示渲染后的结果，否则直接显示图片
* addElement(ele)
* 为拖动操作添加一个元素，添加这个元素只影响数据，不会影响拖动操作时页面元素的外观, 只有火狐支持
* types
* 当前保存的数据类型，返回的是一个字符串的数组
## 历史状态管理
* 过去可以通过hashchange事件来管理状态的变化
* H5通过更新history来管理状态的变化，通常是pushState, replaceState
* pushState(obj, sbj, url)
* 第一个参数是状态对象
* 第二个参数是新状态的标题，目前没有浏览器实现，可以是空字符串
* 第三个参数是可选的相对url
* replaceState
* 参数与上个api相同，不同在于是更新而非压入
* 按下回退按钮或者调用history.back等浏览器动作时会触发popstate事件，可以通过访问时间对象的state属性来得到当前状态对象 | {

# react
* [react参考文档](https://react.docschina.org/)
## react基本认识
* 声明式编程
* 组件化编程
* 跨平台编程
* 高效
* 虚拟dom，不总是修改dom，可以减少更新次数
* dom diff算法，最小化更新的dom数量
## 从demo学习
* 通过一些demo的案列来逐渐了解react中的思想
### react的hello world
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div id="test1"></div>
<script src="../lib/react.development.js"></script>
<script src="../lib/react-dom.development.js"></script>
<script src="../lib/babel.min.js"></script>
<!--默认将jsx语法转换成js语法 -->
<script type="text/babel">
var vDom = <h1>hello world</h1>
ReactDOM.render(vDom, document.getElementById('test1'))
</script>
</body>
</html>
```
### jsx的基本认识
* 全称为javascriptXML
* 本质是react创建的类似于XML的js扩展
* 由于标签名与属性名任意所以叫做XML
* react提供一些api来创建一些*特别*的一般js对象
* js语法 `var vDom = React.createElement('h1', {id: name.toLowerCase()}, content.toLowerCase())`
* jsx语法 `var vDom = <h1 id={name.toLowerCase()}>content.toLowerCase()</h1>`
* 通过调用api会将虚拟DOM转换成真实的DOM
* 编码时只需要操作虚拟DOM对象，react会将其变化转换成真实DOM的变化
* 当标签内的变量是数组时，会被自动遍历返回数组内所有的值
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<header><h1>javascript框架</h1></header>
<div id="frame"></div>
<script src="../lib/react.development.js"></script>
<script src="../lib/react-dom.development.js"></script>
<script src="../lib/babel.min.js"></script>
<script type="text/babel">
var arr = ['jquery', 'angular', 'vue', 'react', 'zepto']
var vDom = <ul>{arr.map((item, index)=><li id={index}>{item}</li>)}</ul>
ReactDOM.render(vDom, document.getElementById('frame'))
</script>
</body>
</html>
```
### 组件
* jsx是面向组件编程
* 组件有两种创建方式
1. 工厂函数简单组件，即一个返回值是标签的函数
2. 类复杂组件，即一个继承自React.component的构造函数，子类的render方法返回值也是标签
* 在组件中返回的内容最上一层必须只有一个标签
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div id="test1"></div>
<div id="test2"></div>
<script src="../lib/react.development.js"></script>
<script src="../lib/react-dom.development.js"></script>
<script src="../lib/babel.min.js"></script>
<script type="text/babel">
function MyComponent(){
return <h2>工厂函数组件(简单组件)</h2>
}
class MyComponent1 extends React.Component{
render(){
return <h2>类组件(复杂组件)</h2>
}
}
ReactDOM.render(<MyComponent />, document.getElementById('test1'))
ReactDOM.render(<MyComponent1 />, document.getElementById('test2'))
</script>
</body>
</html>
```
#### 组件的关键属性state
* state属性是一个对象，react通过监听这个属性的变化来修改虚拟DOM中的内容
* 在react想要更新虚拟DOM时是通过调用类组件的setState属性完成的
* 因此当组件涉及到state时就必须使用类组件
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div id="test1"></div>
<script src="../lib/react.development.js"></script>
<script src="../lib/react-dom.development.js"></script>
<script src="../lib/babel.min.js"></script>
<script type="text/babel">
class MyComponent extends React.Component{
constructor(props) {
super(props)
this.state = {
islike: true
}
this.handleClick = this.handleClick.bind(this) //使用bind函数修改触发函数内的this值
}
handleClick() {
console.log(this) //默认为undefined
var islike = !this.state.islike
this.setState({islike: islike}) //只有通过这种方式修改的state才会重新加载虚拟DOM
}
render() {
return <h1 onClick={this.handleClick}>{this.state.islike?'你喜欢我':'我喜欢你'}</h1>
}
}
ReactDOM.render(<MyComponent />, document.getElementById('test1'))
</script>
</body>
</html>
```
#### prop属性
* 当想要自定义组件内的数据时需要用到prop属性
* 当想给自定义属性设置默认值时需要用到组件的defaultProps属性
* 当给自定义属性添加变量检查时需要引入prop-types的包并且配置组件的propTypes属性
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div id="test1"></div>
<script src="../lib/react.development.js"></script>
<script src="../lib/react-dom.development.js"></script>
<script src="../lib/babel.min.js"></script>
<script src="../lib/prop-types.js"></script>
<script type="text/babel">
let p = {
name: 'aaa',
age: 17,
sex: '女'
}
Person.defaultProps = {
age: 18,
sex: '男'
}
Person.propTypes = {
name: PropTypes.string.isRequired, //设置此属性是string并且是必须的
age: PropTypes.number,
sex: PropTypes.string
}
function Person(props){
return <ul><li>姓名：{props.name}</li><li>年龄：{props.age}</li><li>性别：{props.sex}</li></ul>
}
ReactDOM.render(<Person {...p} />, document.getElementById('test1')) //使用三点运算符对对象进行解包操作，普通的对象没有迭代器不能如此操作
ReactDOM.render(<Person name={'bbb'} />, document.getElementById('test1'))
</script>
</body>
</html>
```
#### refs属性
* 用来标识虚拟DOM的元素
* 通过回调函数的形式将当前元素传递给回调函数
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div id="test1"></div>
<script src="../lib/react.development.js"></script>
<script src="../lib/react-dom.development.js"></script>
<script src="../lib/babel.min.js"></script>
<script src="../lib/prop-types.js"></script>
<script type="text/babel">
class MyComponent extends React.Component{
constructor(props){
super(props)
this.handleClick = this.handleClick.bind(this)
}
handleClick(){
alert(this.input.value)
}
blur(e){
alert(e.target.value) //此事件是react按照W3C的规定封装的，与兼容性无关，如果要阻止此事件的默认行为必须调用e.preventDefault()来进行
}
render(){
return (<div>
<input type='text' ref={input=>this.input=input}/>
<button onClick={this.handleClick}>点击触发事件</button>
<input type='text' onBlur={this.blur} spaceholder='失去焦点提示内容'/>
</div>)
}
}
ReactDOM.render(<MyComponent />, document.getElementById('test1'))
</script>
</body>
</html>
```
#### 功能界面的组件编码流程
1. 拆分组件：拆分界面抽取组件
2. 实现静态组件：使用组件实现静态化页面效果
3. 实现动态组件
* 动态显示初始化界面
* 交互功能(从绑定事件监听开始)
##### 状态数据保存位置
* 当只有一个组件使用这个数据时，将数据保存在这个组件中
* 当有多个组件使用时，保存在上一级的父组件中
##### 在子组件中改变父组件的状态
* 将父组件的状态传递给子组件中
* 状态在哪个组件，更新状态的行为就应该定义在哪个组件

### 表单操作
* 在表单中有两种方法控制表单中元素的内容，第一种是通过操作DOM来实现叫做非受控组件，第二种是通过实时更新state来实现叫做受控组件
#### 非受控组件
* 核心在于通过ref属性来获取虚拟DOM中特定的DOM元素，然后对此DOM元素进行一系列操作，与原生或者jQuery的思想相同
#### 受控组件
* 核心在于通过给元素绑定事件，在每次进行各种操作时实时修改组件的状态来达到重新渲染组件的目的

### react的生命周期
* react的组件从创建，更新到销毁会有一系列的钩子函数被执行，这整个过程被称为生命周期
* 这些钩子函数已经被封装到`React.Component`中，因此子组件是否重写钩子函数是可选的
#### 生命周期的流程
1. 创建组件时(ReactDOM.render)
1. constructor
2. getDerivedStatesFromProps
3. render
4. componentDidMount
2. 更新组件时
1. getDerivedStatesFromProps
2. shouldComponentUpdate
3. render
4. componentDidUpdate
3. 销毁组件时(ReactDOM.unmountComponentAtNode)
1. componentWillUnmount

class Life extends React.Component{
constructor(props){
super(props)
this.state = {
opacity: 1
}
this.interval = setInterval(() => { //组件创建时初始化定时器
console.log('执行...')
if(this.state.opacity<=0) return this.setState({opacity: 1})
this.setState({opacity: this.state.opacity-0.1})
}, 200);
}
handleClick(){
ReactDOM.unmountComponentAtNode(document.getElementById('test1')) //销毁组件
}
componentWillUnmount(){ //当组件将要销毁时执行此钩子，清除定时器
clearInterval(this.interval)
}
render(){
let opacity = this.state.opacity
//可以使用js对象来给元素定义样式
return (
<div>
<h2 style={{opacity}}>{this.props.title}</h2>
<button onClick={this.handleClick}>bye!</button>
</div>
)
}
}
Life.propTypes = {
title: PropTypes.string.isRequired
}
ReactDOM.render(<Life title="hello!!"/>, document.getElementById('test1'))
</script>
</body>
</html>
```
##虚拟DOM与Diff算法
* react效率高的两种原因
### react渲染页面的流程
1. 创建虚拟DOM树
2. 生成DOM树
3. 渲染页面
1. 通过setState修改组件状态
2. 生成新的虚拟DOM树
3. 通过Diff算法比较新旧虚拟DOM树的区别
4. 更新虚拟DOM树中的差异DOM到DOM树中
5. 重新渲染页面
## react应用脚手架
* 通过使用脚手架能够快速构建基于某种库的模板项目
* 包含了所有需要的配置
* 包含了所有依赖
* 可以安装/编译/运行一些简单的效果
* react提供了用来创建react项目的脚手架库:create+react+app
### 项目根目录下的package.json
* 分为三个核心部分
1. 标识(name,version等)
* 用来标记当前项目的一些信息
2. 依赖(dependencies与devDependencies)
* 用来记录当前项目使用了哪些依赖
3. 运行脚本(scripts)
* 用来给一些命令脚本创建成简单的别名，可以通过`npm [run] [命令]`来进行快速运行
## react的ajax请求
* react只关注界面，本身不带跟ajax相关的api
* 只能额外引入第三方库来完成ajax请求
### 常用的ajax第三方库
* jQuery： 比较大，如果只是用ajax部分不推荐引入
* axios：轻量级，建议使用
* 本质是使用XMLHttpRequest
* 是一种promise的形式
* fetch: 原生的一种异步请求
* 老版本浏览器不支持
* 可以使用fetch.js来进行浏览器兼容
```html

<html lang="en">

<meta charset="UTF-8">

<script src="../lib/axios.js"></script>
<script type="text/babel">
class MyComponent extends React.Component{
constructor(props){
super(props)
this.state = {
name: '',
html_url: ''
}
}
componentDidMount(){
// axios.get('https://api.github.com/search/repositories?q=re&sort=stars') //使用axios实现
// .then(res=>{
// const {name, html_url} = res.data.items[0]
// console.log(name, html_url)
// this.setState({
// name,
// html_url
// })
// }).catch(err=>{
// alert(err.message)
// })
fetch('https://api.github.com/search/repositories?q=re&sort=stars') //使用fetch实现
.then(res=>{
return res.json()
}).then(data=>{
const {name, html_url} = data.items[0]
console.log(name, html_url)
this.setState({
name,
html_url
})
}).catch(err=>{
alert(err.message)
})
}
render(){
if(!this.state.html_url){
return <h2>loading...</h2>
}else{
return <h2>the most popular resposity is <a href={this.state.html_url}>{this.state.name}</a></h2>
}
}
}
ReactDOM.render(<MyComponent />, document.getElementById('test1'))
</script>
</body>
</html>
```
## 组件间通信
* 实现两个案例：
1. comment
2. counter-react
3. search
### 通过props传递
1. 共同的数据放在最近的父组件中，特有数据放在子组件中
2. 通过props可以传递一般数据与函数数据，只能一层层的传递
3. 一般数据用于父组件向子组件传递数据，子组件要读取父组件的数据
4. 函数数据用于子组件向父组件传递数据，父组件对读取到的子组件数据从函数中进行操作
### 使用消息订阅(subscribe)-发布(publish)传递
1. 可用PubSubjs第三方库来实现
2. 本质是事件监听与事件触发
### 通过redux来传递
...后面补充
## react-router
* react的一个插件库
* 常用来制作SPA
* 实现一个案例：
1. router
### 路由的理解
* 一个路由就是一种映射关系(key-value)
* key为路由路径，value为Function(后台路由)/Component(前台路由)
#### 后台路由
* 接收到对应路由路径的请求时对客户端发来的数据进行处理并返回响应
#### 前台路由
* 接收到对应路由路径的请求时，浏览器不会发送http请求，但界面会更新对应的组件
### 创建路由的方式
1. 使用BrowserRouter/HashRouter创建自定义路由组件
2. 使用Link或者NavLink来创建路由链接
3. 使用Switch来在一个固定的位置只展示一个路由组件
4. 使用Route或者Redirect来指定自定义路由映射, 在path的属性中可以使用/index:path来让path成为占位符，可以使其在子组件的props.match.params中获取到
## react-UI
1. Material-UI
2. ant-Design-UI
## redux
* redux是一个专门用于状态管理的库，不是react库
* 可以用在vue，angular，react，但主要用于react
* 作用：管理react应用中多个组件共享的状态
* 将组件案例comment使用redux重写
### 运行机制
* react组件从Store中读取state
* react组件通过Action creators创建action然后dispatch产生的action
* Store将发布的previous state与action传递给Reducers
* Reducers产生newstate然后传递给store
### 使用redux的情况
* 尽量少用，但是基本都会使用，由于大项目使用会轻松
* 某个组件的状态需要共享
* 某个状态要在任何地方都能拿到
* 一个组件需要改变全局的状态
* 一个组件需要改变另一个组件的状态
### redux的三个核心对象
#### action
* 标识要执行行为的对象
* 包含两个方面的属性
* type 标识属性，必选
* data 传递的数据，可选
* 例子：
```javascript
const action = {
type: 'INCREMENT',
data: 2
}
```
* Action creator(创建action的工厂函数)
```javascript
const icrement = (number)=>({type: 'INCREMENT'， data: number})
```
#### reducer
* 根据老的state和action, 产生新的state的函数
```javascript
export default function counter(state=0, action){
switch(action.type){
case 'INCREMENT': return state+action.data
case 'DECREMENT': return state-action.data
default: return state
}
}
```
* 要返回一个新的状态
* 不能修改原有的状态
#### store
* 将state，action和reducer联系到一起的对象
* 得到store对象
```javascript
import {createStore} from 'redux'
import reducer from './reducer'
const store = createStore(reducer)
```
* 三个核心方法
* dispatch(action)
* createStore(reducer)
* subscribe(render)
### react插件react-redux
* 用来减轻redux在react中的耦合度
#### 核心api
* Provider
* 让所有组件都可以得到state的数据
```jsx
ReactDOM.render(<Provider store={store}><app /></Provider>, document.getElementById('app'))
```
* connect
* 连接redux与UI组件之间的数据关系
* 用于包装UI组件生成容器组件
```jsx
export default connect(mapStateToProps, mapDispatchToProps)(Counter)
```
### redux异步编程
* 使用redux中间件实现异步编程
* 安装
```
install i redux-thunk
```
* 配置中间件
```javascript
import {createStore, applyMiddleware} from 'redux'
createStore(
reducer, //内部会第一次调用reducer来初始化state
applyMiddleware(thunk)
)
```
* 使用
```javascript
export function incrementAsnyc(number){
return (dispatch)=>{
setTimeout(()=>{
dispatch({type: 'INCRMENT', data: number})
}, 1000)
}
}
```
### redux调试工具
* 安装
1. 安装chrome插件
2. 安装依赖
```
install i redux-devtools-extension
```
* 配置
```jsx
import {composeWithDevtools} from 'redux-devtools-extension'
createStore(
reducer, //内部会第一次调用reducer来初始化state
composeWithDevtools(applyMiddleware(thunk))
)
```
### 使用redux管理多个reducer
* 使用redux的combineReducers将需要管理的属性封装成一个对象
```jsx
export default combineReducers({
counter,
comments
})
```

/**
* Summary of `ReactBrowserEventEmitter` event handling:
*
* - Top-level delegation is used to trap most native browser events. This
* may only occur in the main thread and is the responsibility of
* ReactDOMEventListener, which is injected and can therefore support
* pluggable event sources. This is the only work that occurs in the main
* thread.
*
* - We normalize and de-duplicate events to account for browser quirks. This
* may be done in the worker thread.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.

* We listen for bubbled touch events on the document object.

* contained within that mount point (for example on the background) the

* movement types of events and possibly all events.
*
* @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

* This really simplifies the code.
* ---
* Similar to invariant but only logs a warning if the condition is not met.

// UpdateQueue is a linked list of prioritized updates.
//
// Like fibers, update queues come in pairs: a current queue, which represents
// the visible state of the screen, and a work-in-progress queue, which can be
// mutated and processed asynchronously before it is committed — a form of
// double buffering. If a work-in-progress render is discarded before finishing,
// we create a new work-in-progress by cloning the current queue.
//
// Both queues share a persistent, singly-linked list structure. To schedule an
// update, we append it to the end of both queues. Each queue maintains a
// pointer to first update in the persistent list that hasn't been processed.
// The work-in-progress pointer always has a position equal to or greater than
// the current queue, since we always work on that one. The current queue's
// pointer is only updated during the commit phase, when we swap in the
// work-in-progress.
//
// For example:
//
// Current pointer: A - B - C - D - E - F
// Work-in-progress pointer: D - E - F
// ^
// The work-in-progress queue has
// processed more updates than current.
//
// The reason we append to both queues is because otherwise we might drop
// updates without ever processing them. For example, if we only add updates to
// the work-in-progress queue, some updates could be lost whenever a work-in
// -progress render restarts by cloning from current. Similarly, if we only add
// updates to the current queue, the updates will be lost whenever an already
// in-progress queue commits and swaps with the current queue. However, by
// adding to both queues, we guarantee that the update will be part of the next
// work-in-progress. (And because the work-in-progress queue becomes the
// current queue once it commits, there's no danger of applying the same
// update twice.)
//
// Prioritization
// --------------
//
// Updates are not sorted by priority, but by insertion; new updates are always
// appended to the end of the list.
//
// The priority is still important, though. When processing the update queue
// during the render phase, only the updates with sufficient priority are
// included in the result. If we skip an update because it has insufficient
// priority, it remains in the queue to be processed later, during a lower
// priority render. Crucially, all updates subsequent to a skipped update also
// remain in the queue *regardless of their priority*. That means high priority
// updates are sometimes processed twice, at two separate priorities. We also
// keep track of a base state, that represents the state before the first
// update in the queue is applied.
//
// For example:
//
// Given a base state of '', and the following queue of updates
//
// A1 - B2 - C1 - D2
//
// where the number indicates the priority, and the update is applied to the
// previous state by appending a letter, React will process these updates as
// two separate renders, one per distinct priority level:
//
// First render, at priority 1:
// Base state: ''
// Updates: [A1, C1]
// Result state: 'AC'
//
// Second render, at priority 2:
// Base state: 'A' <- The base state does not include C1,
// because B2 was skipped.
// Updates: [B2, C1, D2] <- C1 was rebased on top of B2
// Result state: 'ABCD'
//
// Because we process updates in insertion order, and rebase high priority
// updates when preceding updates are skipped, the final result is deterministic
// regardless of priority. Intermediate state may vary according to system
// resources, but the final state is always the same.

This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
## Available Scripts
In the project directory, you can run:
### `npm start`
Runs the app in the development mode.<br>
Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
The page will reload if you make edits.<br>
You will also see any lint errors in the console.
### `npm test`
Launches the test runner in the interactive watch mode.<br>
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
### `npm run build`
Builds the app for production to the `build` folder.<br>
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.<br>
Your app is ready to be deployed!
See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
### `npm run eject`
**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
## Learn More
You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
