Which jQuery selector is more efficient?
|
<p>I was just wondering if there is a reason why I should prefer this</p>
<pre><code><div class="identifying-class">bla bla</div>
<div class="identifying-class">bla bla</div>
var interestingElements = $("div.identifying-class);
</code></pre>
<p>over this</p>
<pre><code><div data-identifying-attr="true">bla bla</div>
<div data-identifying-attr="true">bla bla</div>
var interestingElements = $("div[data-identifying-attr]");
</code></pre>
<p>Are attribute based selectors quicker /slower/the same speed as class based selectors?
Is one method deemed better practice than the other - if so why?</p>

Passing function pointers - semantics
|
<blockquote>
<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/6893285/why-do-all-these-crazy-function-pointer-definitions-all-work-what-is-really-goi">Why do all these crazy function pointer definitions all work? What is really going on?</a> </p>
</blockquote>
<p>I would be grateful for an explanation why in the code</p>
<pre><code>void f(int& i)
{
i++;
}
void g(void (passed_f)(int&),int& a) //`passed_f` equivalent to `*passed_f`
{
passed_f(a);
}
int main()
{
int n=0;
g(f,n); //`f` is equivalent to `&f`
}
</code></pre>
<p>both of the equivalences hold, in the sense of not producing any errors, and giving exactly the same result, <code>1</code>. It seems, that it does not matter if we accept in <code>g</code> a pointer to a function, or a function itself... I also presume that [c]-tag is appropriate.</p>

Filtering values against an expression and a list
|
<p>I'm writing a bot for the IMified network.</p>
<p>I want to filter the items processed by my bot by only accepting certain values into my script.</p>
<p>This is what I'm using right now:</p>
<pre><code>$items = array('botkey', 'userkey', 'network', 'user', 'channel', 'msg', 'step');
foreach ($_POST as $key => $value)
{
if (in_array($key, $items) || preg_match('value\d*', $key))
{
$this->data[$key] = $value;
}
}
</code></pre>
<ol>
<li>Is there any way to do this better?</li>
<li>Why doesn't my regular expression work – it is meant to only allow keys named like <code>value1234</code> or anything similar ("value" + number), but it doesn't let <em>anything</em> through.</li>
</ol>

Asp.net MVC Medium Trust Remote Host
|
<p>I’m having issues getting my asp.net mvc application working on my remote host.</p>
<p>The host needs all sites to be working with medium trust.</p>
<p>I’ve modified my machine web.config “\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG” and created a new project so my new application web.config picks up the changes.</p>
<p><strong>Machine web.config</strong></p>
<pre><code> <location allowOverride="true">
<system.web>
<securityPolicy>
<trustLevel name="Full" policyFile="internal"/>
<trustLevel name="High" policyFile="web_hightrust.config"/>
<trustLevel name="Medium" policyFile="web_mediumtrust.config"/>
<trustLevel name="Low" policyFile="web_lowtrust.config"/>
<trustLevel name="Minimal" policyFile="web_minimaltrust.config"/>
</securityPolicy>
<trust level=" Medium " originUrl=""/>
</system.web>
</location>
</code></pre>
<p>When I upload to the host I get an error about System.Security.Permissions.ReflectionPermission and changing the trust level but when I click refresh I get an error about my route.</p>
<p>The route works fine locally so I can only put it down to the trust levels.</p>
<p>I may be missing something as I’ve not deployed to a remote host before.</p>
<p>Do I need to add anything to the website web.config?</p>
<p>Any help or advice would be great.</p>
<p>Also when I make a change to my machine web.config will my applcation pick up these settings when I next build in visual studio?</p>

IPostbackeventhandler returning no results for an automated table

Is it possible to resize the canvas in android?

<p>[android]
I have a LinearLayout which contains 2 views, 1st is imageView and th 2nd one have canvas on it.
if I do mLinearLayout.addView(i); and then mLinearLayout.addView(c); it shows both but if I do it in reverse oder (mLinearLayout.addView(c) and then mLinearLayout.addView(i)) the it only shows canvas.
I wanted to share the screen between these 2 views. Can anybody help me on this?</p>
<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mLinearLayout = new LinearLayout(this);
mLinearLayout.setBackgroundColor(0xff74AC23);

Android Noteadv2. The confirm button has no click listener
|
<p>I'm looking at the Noteadv2 in the android tutorials. Everything works just hunky dory, but one small thing. My "confirm button" has no on-click listener. I know why this happens and the code from the solution is effectively identical, but the expectation the tutorial gives you is that you should be able to create and delete a note. So far.. no good.</p>
<p>So we start our call stack in creating the activity in Notepadv2.onMenuItemSelected(...). It says stuff like this:</p>
<pre><code>@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch(item.getItemId()) {
case INSERT_ID:
createNote();
return true;
}
return super.onMenuItemSelected(featureId, item);
}
</code></pre>
<p>Then our friend createNote() says:</p>
<pre><code> private void createNote() {
Intent i = new Intent(this, NoteEdit.class);
startActivityForResult(i, ACTIVITY_CREATE);
}
</code></pre>
<p>So android, so nicely, routes a request and CRUDs us a a NoteEdit class based on our manifest. All great so far. Here's the funny bit in NoteEdit.onCreate():</p>
<pre><code>@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.note_edit);
setTitle(R.string.edit_note);
mTitleText = (EditText) findViewById(R.id.title);
mBodyText = (EditText) findViewById(R.id.body);
Button confirmButton = (Button) findViewById(R.id.confirm);
mRowId = null;
Bundle extras = getIntent().getExtras();
if (extras != null) {
</code></pre>
<p>the last two lines are the crux. After this point we add a click event listener on the confirm button, which never gets done. </p>
<p>When we yank the extras out of the current intent for our activity, those extras are not there. Makes sense right? They were never set cuz this is new.. since the extras are null the if-statement drops out and we get stuck on the edit screen while debugging.</p>
<p>Is there a default setting I missed. Did I skip a step or is eclipse playing silly bugger again?</p>
<p>Thanks for reading.</p>

check for valid arguments

<p>So let's define a few functions:</p>
<pre><code>def x(a, b, c): pass
def y(a, b=1, c=2): pass
def z(a=1, b=2, c=3): pass
</code></pre>
<p>Now, what's the best way to, given a pointer to <code>x</code>, <code>y</code>, or <code>z</code> (<code>p</code>), a tuple of args (<code>a</code>) and a dictionary of kwargs (<code>k</code>), check to see if </p>
<pre><code>p(*a, **kw)
</code></pre>
<p>would produce any exception regarding having not enough arguments or incorrect arguments, etc—<em>without</em> actually calling <code>p(*a, **kw)</code> and then catching the exceptions raised.</p>
<h2>Example</h2>
<pre><code>def valid(ptr, args, kwargs): ... #implementation here
valid(x, ("hello", "goodbye", "what?"), {}) # => True
valid(x, ("hello", "goodbye"), {}) # => False
valid(y, ("hello", "goodbye", "what?"), {}) # => True
valid(y, (), {"a": "hello", "b": "goodbye", "c": "what"}) #=> True
valid(y, ("hello", "goodbye"), {"c": "what?"}) #=> True

iPhone - content size of a UITableViewController

<p>I am on a view and I will show a TableViewController.</p>
<p>This app is universal. So, when I show this TableViewController on iPad I will show it inside a popover and on the iPhone I will push it with a navigationController.</p>
<p>Inside the tableViewController class I need to know the bounds of the parent view where this object is contained, that is the internal size of the popover (on the iPad) and the size of the view where the controller were pushed on the iPhone.</p>
<p>How do I access these values?

Thinking of two elements as "the same"
|
<p>I have two jQuery elements, <code>$link = $('<a>')</code> and <code>$input = $('<input/>')</code>.</p>
<p>Although they are two different types of elements, they are in my code (and in my mind!) very linked:</p>
<p>1) Conceptually, they are different representations of one object.</p>
<p>2) They share the same attributes.</p>
<p>3) When one is displayed on the screen, the other is hidden.</p>
<p>Until now, I have used <code>.data()</code> to perform a link between the two:</p>
<pre><code>$link.data('$input', $input);
$input.data('$link', $link);
</code></pre>
<p>As my code became more and more complex, this solution has proved confusing and messy.</p>
<p>Is there a different approach I may want to consider? For example, is there a way to keep the attributes of the two elements continually synced? Is there a way to make one "meta-object" out of the two? etc.</p>

Issue related to state maintenance
|
<p>I have 10 views with <code>UINavigationController</code> in hierarchy. Now when I want to go back from 10 to 9, and so on with back button, which method should I use?</p>
<ol>
<li><code>popviewController</code></li>
<li><code>popToViewController</code></li>
</ol>
<p>I have set a fixed value for all views. At application launch, I get that value. For that value I initialize <code>rootviewController</code> with use of <code>UINavigationController</code>. And my <code>rootviewController</code> is nothing but the first view and after that on next line, I'm pushing a particular view.</p>

Static variable definition order in c++
|
<p>Hi i have a class tools which has static variable std::vector m_tools. </p>
<p>Can i insert the values into the static variable from Global scope of other classes defined in other files. </p>
<p>Example: </p>
<p>tools.h File </p>
<pre><code>class Tools
{
public:
static std::vector<std::vector> m_tools;
void print()
{
for(int i=0 i< m_tools.size() ; i++)
std::cout<<"Tools initialized :"<< m_tools[i];
}
}
</code></pre>
<p>tools.cpp File</p>
<pre><code>std::vector<std::vector> Tools::m_tools; //Definition
</code></pre>
<p>Using register class constructor for inserting the new string into static variable.</p>
<pre><code>class Register
{
public:
Register(std::string str)
{
Tools::m_tools.pushback(str);
}
};
</code></pre>
<p>Different class which inserts the string to static variable in static variable</p>
<p>first_tool.cpp</p>
<pre><code>//Global scope declare global register variable
Register a("first_tool");
////////
</code></pre>
<p>second_tool.cpp</p>
<pre><code>//Global scope declare global register variable
Register a("second_tool");
</code></pre>
<p>Main.cpp</p>
<pre><code>void main()
{
Tools abc;
abc.print();
}
</code></pre>
<p>Will this work?</p>
<p>In the above example on only one string is getting inserted in to the static list. Problem look like "in Global scope it tries to insert the element before the definition is done"
Please let me know is there any way to set the static definiton priority? Or is there any alternative way of doing the same.</p>

How to snoop on $("<p>") calls?
|
<p>I was wondering how i snoop on dom modification events. I tried using the $.sub() to listen but it seems a little overfill to use another wrapper from jquery to get this affect. </p>
<p>Demo is here <a href="http://jsfiddle.net/sr5RE/2/" rel="nofollow">http://jsfiddle.net/sr5RE/2/</a></p>
<p>i.e this works</p>
<pre><code>var $sub = jQuery.sub();
$sub.fn.init = function(selector){
alert("Success");
return $.fn.init.apply($sub.fn.init, arguments);
};
$sub("<p/>");
</code></pre>
<p>but calling $ then it doesn't</p>
<pre><code>$("<p/>");
</code></pre>
<p>And obviously this will loop</p>
<pre><code>$.fn.init = function(selector){
alert("Success");
return $.fn.init.apply($sub.fn.init, arguments);
};
$("<p/>");
</code></pre>
<p>Any ideas?</p>

ASP.Net Wizard - How to clear contents of web controls
|
<p>I have an ASP.NET wizard control where I loop back, <code>wiz.MoveTo(wiz.WizardSteps[0])</code>, to the first step in the wizard in the FinishButtonClick event handler.</p>
<p>I then also want to clear all content for all controls in the steps?</p>
<p>The problem is that because of viewstate the controls in the wizard steps remember their
values from the previous submission?</p>
<p>I cannot use enableviewstate=false on controls as they need to be able to remember their state (back and forth) between steps?</p>
<p>What is the easiest way to clear the viewstate of all controls only when the FinishButtonClick event occurs?</p>
<p>Thanks!</p>

How to specify height of view to be 1/3 of screen height
|
<p>I have created a view (actually a webview):</p>
<pre><code><WebView
android:id="@+id/myWebView"
android:layout_width="match_parent"
android:layout_height="@dimen/input_height"
/>
</code></pre>
<p>Which refers to the height in another xml file:</p>
<pre><code><resources>
<dimen name="key_height">50dip</dimen>
<dimen name="candidate_font_height">16sp</dimen>
<dimen name="candidate_vertical_padding">6sp</dimen>
<dimen name="input_height">280dip</dimen>
</resources>
</code></pre>
<p>Where I have set the <code>input_height</code> as <code>280dip</code> which I understand to mean 280 pixels (device independently) of an approximately 320 pixel (or emulated 320ish pixel) height.</p>
<p>On my two devices (small sony ericsson xperia x10 mini with 320 pixel screen, and old htc desire), it works fine, providing a view height of approximately 1.3 of the screen height. One of my testers is using a samsung galaxy S and they are reporting that the view takes up more than the entire screen.</p>
<p>I assume the issue is something to do with screen density, but I thought using <code>dip</code> would circumvent that issue.</p>
<p>How should I define my layout view to avoid this problem?</p>

jQuery in Wordpress - Why is it not working?
|
<p>I am using this as my starter template: <a href="http://html5reset.org/" rel="nofollow">www.html5reset.org/</a></p>
<p>It's pretty nice, but I believe something is wrong with jQuery in there.</p>
<p>In the <code>functions.php</code> it says:</p>
<pre><code>// Load jQuery
if ( !function_exists(core_mods) ) {
function core_mods() {
if ( !is_admin() ) {
wp_deregister_script('jquery');
wp_register_script('jquery', ("//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"), false);
wp_enqueue_script('jquery');
}
}
core_mods();
}
</code></pre>
<p>This seems fine to me - is it alright?</p>
<p>There also is a premade JS file. In this file it says:</p>
<pre><code>// remap jQuery to $
(function($){})(window.jQuery);
</code></pre>
<p>I don't know really what this does, but it seems also ok.</p>
<p>To test if jQuery works, I tried the following - none of it is woking, jQuery is not defined.</p>
<pre><code>$(document).ready(function() {
alert("This is a test.");
});
jQuery(document).ready(function() {
alert("This is a test.");
});
$(document).ready(function($) {
alert("This is a test.");
});
</code></pre>
<p>So, can you tell ma what could be wrong with this? Thank you!</p>

Android - Draw bitmap as one color
|
<p>I have several bitmaps (game sprites) which I'd like to draw into another bitmap, however each non-transparent pixel of the source bitmap should be drawn using a single color, ignoring the original pixel color of the source. Basically, I'm trying to use the sprite as a "stamp" of a single color to be drawn into the destination bitmap.</p>
<p>I believe I should be using canvas.drawBitmap (Bitmap bitmap, Matrix matrix, Paint paint), however I'm not exactly sure how I should initialize the paint object. Is this approach correct?</p>

Page Initialization: Does one need onload?
|
<p>Regarding this <a href="http://stackoverflow.com/questions/886668/window-onload-is-not-firing-with-ie-8-in-first-shot">SO</a> article and this <a href="http://stackoverflow.com/questions/5168022/the-window-onload-event-is-not-firing-in-ie8">SO</a> article. I looked at these after noticing my web app does not fire in IE8...I don't care about backward compatibility at the moment but if it's one line of code why not? Anyways the other issue I was having is the onload event waits for all the content to load...so the user has no controls if he/she is waiting for images to download. This led me to believe that I should just use</p>
<pre><code><script type='text/javascript'>my_initialize_function()</script>
</code></pre>
<p>placed in the html where I want the page to initialize.</p>
<p>and say to bye to</p>
<pre><code>window.onload = initializePage;
</code></pre>
<p>or</p>
<pre><code>window.addEventListener('load',initialize_page);
</code></pre>
<p>or any similar.</p>
<p>My question is: Is this a valid approach to initializing one's page?</p>
<p>PS: I'm not using any libraries including JQuery...and obviously I would not try to initialize elements that have not been loaded yet.</p>

Assist with Python script
|
<p>I have written a code in Python, and I want to change it.
I use it when I am performing a penetration tests in my organization and I want to make my script better.
The script gets a username that I entering and it connect to the SMTP server over port 25 and check if the user exists or not.
Here is the script:</p>
<pre><code>#!/usr/bin/python
import socket
import sys
if len(sys.argv) != 2:
print "Usage: vrfy.py <username>"
sys.exit(0)
# Create a Socket
s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Connect to the Server
connect=s.connect(('192.168.0.10',25))
# Recieve the banner
banner=s.recv(1024)
print banner
# VRFY a user
s.send('VRFY ' + sys.argv[1] + '\r\n')
result=s.recv(1024)
print result
# Close the socket
s.close()
</code></pre>
<p>The changes that I want to perform are the following:
Instead of entering only one username to check, I want to mention a location of a txt file and the script will read all the usernames it contains.</p>
<p>Also, I what that the IP address at the script wont be hard coded and I will need to insert it every time I am using the script.
Many thanks in advance,</p>

C# Language Question: priority of matching
|
<p>I'm reading book "C# Language", and hit this example from Page 123-124:</p>
<p>The meaning of a name within a block may differ based on the context in which the name is used. </p>
<p>In the example</p>
<pre><code>using System;
class A { }
class Test
{
static void Main()
{
string A = "hello, world";
string s = A; // Expression context
Type t = typeof(A); // Type context
Console.WriteLine(s); // Writes "hello, world"
Console.WriteLine(t); // Writes "A"
}
}
</code></pre>
<p>the name A is used in an expression context to refer to the local variable A and in a type
context to refer to the class A.</p>
<p>I'm fine with the visibility of class A. However, here (<code>Type t = typeof(A)</code>) class <code>A</code> preceded string <code>A</code>.
So, what is the "priority" or "sequence" of matching/choosing a possible "A"?</p>

What is the purpose of marker interface?

<a href="http://stackoverflow.com/questions/1023068/what-is-the-purpose-of-a-marker-interface">What is the purpose of a marker interface?</a> </p>
</blockquote>
<p>I know what is marker interface - An interface with no methods.
Example: Serializable, Remote, Cloneable.</p>
<p>I am wondering what is the purpose of marker inteface. This is my understanding:-</p>
<p>Basically it is just to identify the special objects from normal objects. Like in case of serialization , objects that need to be serialized must implement serializable interface and down the line writeObject() method must be checking somewhere if it is a instance of serializable or not. As far as i think ,Thats the only purpose for which writeObject using interface serializable(marker interface). Right? or jvm provides some extra functionality too on the basis of serializable interface?</p>
<p>Similar kind of logic is true for cloneable interface.</p>
<p>Now lets see how it is useful.</p>
<p>Lets say in a application we have 1000 value objects.We want to serialize only 100 specific objects . Now JDK has said that programmer role is just to mark the object as special with marker interface in this case its serializable interface.Now JDK will take care of that which object to serialize or not?</p>
<p>Yes we could achieve this kind of behaviour with some kind of bollean flag . but that
would be a bad approach.</p>
<p>Similarily we can say in case of user defined marker interface , we can distinguish special objects with help of marker interface.Like we can use instance of operator to determine if it is a instance of that particular interface . If yes proceed in case of No throw some exception.</p>
<p>Please let if above understanding is correct?</p>

How to determine if the flight segment is transatlantic or transpacific in PHP?
|
<p>Given the airport code for the origin and destination region of a flight I need to determine if this flight segment is transpacific or transatlantic. </p>
<p>This is the psuedocode of the best solution I came up with so far.</p>
<p>1.determine the country and the continent(region) of the airport codes.
2.If the origin region is America and the destination region is Europe or Africa or vice versa, the flight segment is transatlantic.
3.If the origin region is America and the destination region is Asia-Pacific or Australia or vice versa, the flight segment is transpacific.</p>
<p>I am not 100% confident of this algorithm. </p>
<p>Can anyone recommend an algorithm, a webservice or any kind of tool to determine if a flight segment is transpacific or transalantic? I am using PHP.</p>

How to display indexDB data on initial page rendering
|
<p>I have a Web page using JavaScript where I cache a large amount of data which I use to populate option tags of a select statement. I have implemented this using localStorage but it is very very slow (it would be much faster regenerating/reloading from the server). IndexDB looks promising as a solution.</p>
<p>All the examples I have been able to find have an indexDB database open, upgrade (configure/load) if necessary. However, to display the indexDB data, the examples implement a button with an onclick function. What I want is to display the indexDB data on the 1st rendering of the page (to load option tags of a select statement).</p>
<p>I have tried to do this but it seems because of the asynchronous callbacks make me unable to create a transaction on the initial rendering of the page hence unable to read the indexDB data.</p>
<p>Is there a way to read the indexDB data on 1st page rendering?</p>
<p>Thanks! </p>

Android - failed to open zip archive

<p>I am downloading apk file from web and storing him into Context.getCacheDir(). I am downloading file by HttpURLConnection - I am not asking actually on the code (it is fully working), so I am not posting it here. I successfully initiate download. File is downloaded into cache and then is prompted installation - but system cannot open my APK and writes error of analysis.</p>
<p>Hence problem is as follows:</p>
<pre><code>03-31 16:48:43.740: INFO/ActivityManager(59): Start proc com.android.packageinstaller for activity com.android.packageinstaller/.PackageInstallerActivity: pid=620 uid=10026 gids={}

</code></pre>
<p>Problem is - I don't have permission to access programaticaly /cache. Is there any way how to solve it? I don't want to use external storage as a download directory (installation process works when I download file to external storage), cache is great because the file won't be accessible for general user from file manager and that's what I want. Thanks for your thoughts.</p>
<p>This problem has been for me unsolvable for over a month now...</p>
<p><strong>Edit:</strong> Still no solution, I am trying to think that I found 1st thing, that is not possible with Android</p>
<p><strong>Edit2:</strong> I must have been looking bad - my downloaded apk is present in cache... There is still no permission to allow install from that dir?</p>

IE window.resize how to stop resizing it?

<p>I recently write a window.resize in javascript for resizing the browser window for certain conditions.e.g. start with vertical resolution 900 keep resizing the browser window until height become 400 then stop resizing. But browser window keep resizing as I clear the handler for it.
Is there any way to just stop browser resizing after some limit?</p>
<pre><code> //here is the sample code
Sys.Application.add_load(function(sender, args) {
$addHandler(window, 'resize', window_resize);
});
var resizeTimeoutId;
var initWdth = (document.body.clientWidth - 200);
function window_resize(e) {
window.clearTimeout(resizeTimeoutId);
resizeTimeoutId = window.setTimeout(function() {
if (screen.height >= 768 && initWdth <= (document.body.clientWidth - 200)) {
document.body.scroll = "no";
//code here
//Enter if window maximized
//working fine.
}
else {
document.body.scroll = "yes";
if (document.documentElement.clientHeight >= 400) {
//mean 400 is our limit
}
else {
//Now stop resizing everything //Div's table etc
//browser window should stop resizing.
//$clearhandler(window, 'resize', window_resize); worked but browser window can't stop resizing
//after clearing the handler resize event not working but browser window keep resizing.

Adding values from a list of checkboxes to a textbox
|
<p>I am new to jQuery, so I am not familliar with syntax of it.</p>
<p>The problem I am facing right now is, I have a dropdown list with some values and corresponding checkboxes. When someone selects a particular value from the dropdown i.e checks a checkbox from dropdown, I want to add the 'value' of the checkbox to the textbox which is besides the dropdown of checkboxes.</p>
<p>The code I have come up with is</p>
<pre><code>$(".productr-dropdown li input[type='checkbox']").click(function(e){
var cmd = $(this).val();
addToTextBox(cmd);
});
function addToTextBox(cmd){
command = $(".z:eq(2)").find("#platform_Command").val();
if (command.indexOf(' '+cmd+' ')>=0)
return;
else {
// THIS IS THE NEXT PART WHERE I AM STUCK
// I don't know how to add/replace the contents of 'cmd'
// to the contents of 'command'(which is the value of the textbox)
}
}
</code></pre>
<p>To better explain my problem I will write a use case here,
The user checks a checkbox from the dropdown, e.g the value of the checkbox checked is 'abc', the textbox in which I want to add this 'abc' already has a value say 'xyz hijkl defg'. what should happen is the value'abc' should get added to the textbox in such a way that the value of the textbox would be'xyz abc hijkl defg' </p>
<p>The problem I have is I am not sure whether I am invoking the correct event also.</p>
<p>One more approach I have in mind is,
$(document).click(function(e) {
$(".productr-dropdown").hide();
$(".productr-dropdown").each(["input='checkbox':checked"], function (e){
addToTextBox($(this).val());
});
});</p>
<p>Which one is better ?</p>
<p>What is the syntax to only select values in the dropdown which are checked ?</p>

var myVideo = document.getElementsByTagName('video')[0];
myVideo.src = "1.m4v";
myVideo.load();
myVideo.play();
myVideo.addEventListener('ended', myNewSrc, false);
}
</script>
</head>
<body onload="myAddListener()">
<video controls
src="1.m4v">
</video>
</body>
</html>
</code></pre>
<p>It seems the problem is video1 can switch to video2, but video2 can't switch back to video1.
How can I write a script to loop 1 > 2 > 1 > 2 > 1 > 2 > 1?
IS it possible to switch more than three video source?
I don't know what the bottom link talking about but it seems useful to help me.</p>

C# calling a static method using a Type
|
<p>How do I call a static method from a Type, assuming I know the value of the Type variable and the name of the static method?</p>
<pre><code>public class FooClass {
public static FooMethod() {
//do something
}
}
public class BarClass {
public void BarMethod(Type t) {
FooClass.FooMethod() //works fine
if (t is FooClass) {
t.FooMethod(); //should call FooClass.FooMethod(); compile error
}
}
}
</code></pre>
<p>So, given a Type t, the objective is to call FooMethod() on the class that is of Type t. Basically I need to reverse the typeof() operator.</p>

Javascript function call not behaving the way I expect
|
<p>here is the html:</p>
<pre><code><table width="100%" height="100%" border="0" cellpadding="0" cellspacing="0">
<tr align="center" valign="middle">
<td width="10" class="pagestyle" onClick="pageNo(-1);" align="right">&laquo;</td>
<td id="pageNum" class="pagestyle">1/5</td>
<td width="10" class="pagestyle" onClick="pageNo(+1);" align="left">&raquo;</td>
</tr>
</table>
</code></pre>
<p>And here is the corrosponding javascript:</p>
<pre><code>var page = 0;
function pageNo(off) {
if (((page + off) > -1) && ((page + off) < 6)) {
page = page + off;
parseRSS(page);
} else if ((page + off) === 6) {
page = 0;
parseRSS(page);
} else if ((page + off) === -1) {
page = 5;
parseRSS(page);
}
}
</code></pre>
<p>What this is supposed to do is start with page 1, which it does, and count up or down depending on the link clicked. However, when we get to page 5, I have to click twice to go back to page 1. What is causing the double-click behavior?</p>

something wrong in this j query
|
<pre><code>function dowork()
{
$(".wrappedElement").removeClass("wrappedElement");
$(".wrappedElementout").removeClass("wrappedElementout");
var a=$("div#DepPart select option:selected").val();
$("div#TestPart select option[value^=a]").addClass("wrappedElement");
$("div#TestPart select option[value!=a]:not(div#TestPart select option[value^=a])").addClass("wrappedElementout");
}
</code></pre>
<p>In this function var a gets the value (a="HMT") in string format and when i uses this value as part of the jQuery selector it does't work for some reason. Can anybody suggest what the solution may be?</p>

How can I block on readline() in python so I don't have to poll?

</blockquote>
<p>I am trying to monitor a log file that is being written to (like tail -f), and I can't figure out how to make readline() block once it reaches eof. All of my googling has only turned up solutions to make things NON-blocking. Does anyone know a way to make a call like this block, so I DON'T have to poll? (I'm perfectly capable of polling and sleeping already, so if you suggest that I'm going to rate you down.)</p>
<pre><code>fh = open('logfile')
# I only want new output, so seek to the end of the file
fh.seek(-1,2)
while True:
# I want this to block until the file has new output,
# but it sees eof and returns '' immediately
line = fh.readline()
# ... process the line

Problems with pinch zoom on Android
|
<p>I recently discovered a bit of code to keep the backgrounds stable, when pinch zooming on iphone/ipad.
However I am running test on my website on my Android, and when I pinch zoom, the background image, which covers the whole site in the body tag, jumps all over the place.
So is there any code that can counteract this on Android devices, so my website can behave at an acceptable standard?</p>

Enhancing Web Application Security
|
<p>"The dynamic JavaScript is another part that could use some additions in the future
as well. If another variable could not be found in the future, one could add a bogus
variable to make it even more difficult for an attacker to analyse the code and raise the
cost for the attacker to an extent where it is hopefully no longer worth performing the
attacks. The PHP script that generates the script should also be updated to make the
JavaScript more dicult to read and understand for a normal person."</p>
<p>Hi, pls Im working on a research area on my thesis work(Security in Web application Authentication) and I came across the above statement on part of the future work the person wrote on his thesis.I dont know whether its talking about the increasing the variable of the encryption method or other things I dont comprehend. I need clarification on how I can go about it in order to have my own contribution as well for my thesis. Thanks</p>
