4,869,180 | 4,869,181 | How can I set up a $.fn. function so it gets executed when called? | <p>I have the following code:</p>
<pre><code> function init() {
var $contentButtonPanel: JQuery = $('#content-button-panel')
$contentButtonPanel
.find('.arbo .toggle, .collapsible-list li:has(ul) > :first-child, .collapsible-list li:has(ul) > :first-child + span')
.click(function (event) {
$(this).toggleBranchOpen();
});
}
$.fn.toggleBranchOpen = function () {
this.each(function () {
$(this).closest('li').toggleClass('closed');
});
return this;
};
</code></pre>
<p>When I debug I can see that the $(this).toggleBranchOpen(); line is reached. However the code does not go inside that function. </p>
<p>Is this a problem with the way that toggleBranchOpen is declared? Note that the only time toggleBranchOpen is used is inside of the init function click event. Is it possible for me to move that code into the init and simplify things?</p>

5,661,616 | 5,661,617 | jquery to color code text | <p>I give php code examples on my site and was wondering if their was a way I could colour code them so that it is easier to read like an IDE would do. I always display the code in a div with a class of code and then in pre tags. See my example below.</p>
<pre><code><div class="code">
<pre>
<?php
echo 'hello world';
?>
</pre>
</div>
</code></pre>
<p>I was wondering if there was a way to do it with jQuery like in a sort of string match way. So give jquery an array of strings that should be blue for example, and then jQuery would look through the code blocks and any words that match it adds a class of blue to them or something? Anyone know of how I would achieve this? Maybe there is a much simpler way already? </p>
<p>Thanks</p>

1,201,576 | 1,201,577 | Generate Dynamic Pages With ASP.Net | <p>I am currently programming classic asp and have my own CMS and it's a good one but I'd like to move it to c#.net meanwhile. (customers don't like this old language anymore)
on my current CMS I generate Pages physically with ASP FSO(filesystem object).
so my question is should i use this method at asp.net too? I reviewed some .NET cms and realized that they don't build pages physically.</p>
<p>For example after working with a CMS noticed that When I type <a href="http://localhost/PageName.aspx" rel="nofollow">http://localhost/PageName.aspx</a> in address bar actually it's still in default.aspx but it regenerated page with contents that belong to PageName.aspx's PageID at database.</p>

1,567,219 | 1,567,220 | jQuery trim and remove on parent break child events | <p>Note: I have a workaround to this problem, but I'd prefer to comma-separate the values as I describe below rather than separating them with spaces (which is what my workaround does).</p>
<p>I have an ASP.NET website that allows instructors to choose from a DropDownList of preset comments and apply these comments to students in their classes. I display the students and comments inside a GridView, and use a Label to display any comments that already exist in the database (removing them from the DropDownList in the process). When an instructor selects one of these comments and clicks a button, my jQuery function:</p>
<ol>
<li>Pulls the selected value and text out of the option (provided it isn't the default option).</li>
<li>Checks Label.children().length, and appends a ", " to the text if it's greater than zero.</li>
<li>Creates a <code><span></code> tag with a hidden field containing the value and text.</li>
<li>Appends the text inside the span.</li>
<li>Closes the span.</li>
<li>Attaches an onclick event to the span.</li>
<li>Removes the original option from the DropDownList.</li>
</ol>
<p>The span tag's onclick event does the reverse of what I describe above -- it pulls the value and text out and re-creates the option inside the drop-down menu. Additionally, it replaces strings like ", , " with ", " in the parent Label. I've found that when I replace these strings (which lie outside the spans I've attached the onclick events to) that the onclick events go away.</p>
<p>I'm familiar with .live(), but because each row in this GridView contains a unique reference to the particular student and class currently in use, I can't know the values that each row needs to pass into the funciton ahead of time. Is there any solution to this problem other than my described workaround or re-attaching the onclick event?</p>

<li>Using AJAX send as much information about the website back to a PHP script on my server. </li>

1,454,961 | 1,454,962 | Adding Views to another View | <p>Is there a possibility to add a view or derivative (button, textview, imageview etc...) to another view without having to go through layouts?</p>
<p>I have a class called ScreenView, it derives from View (e.g. public class ScreenView extends View).
I wanted to display text into it, labels, images etc..</p>
<p>On an iPhone it's trivial, simply create my objects and use addSubview method ; you can embed any UI objects into another. Most UI toolkits work that way too.</p>
<p>Problem with layouts is that I haven't found an easy way to properly position a subview (say a text view) in a given location of the enclosing View. I want one to contain the other...</p>
<p>I was hoping I had missed something in the documentation (which is far from being intuitive that's for sure) and I could do something like myView.addView(subview). But it ain't so :)</p>
<p>As a side question, what is the closest to iPhone's UILabel in the Android world?
A UILabel can contain a text or a graphic. Right now I've been using TextView and ImageView but they aren't anywhere as flexible when it comes to layout as a UILabel</p>
<p>Edit: Making my View inherit from ViewGoup instead, let me add subview..
However, I want to draw in my view. I found that when ScreenView extends ViewGroup, the onDraw function is never called then.</p>
<p>Something like:</p>
<pre><code> @Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL);
// make the entire canvas yellow
paint.setColor(Color.YELLOW);
canvas.drawPaint(paint);
}
</code></pre>
<p>Would paint in yellow my view if ScreenView extends View ; but not if it extends ViewGroup.</p>
<p>How do you draw directly in the view then?</p>

When I try to register a clientscript - an alert box for instance, in the Page_Load it works fine. However if I try to do the same from any method or event handler of the same class it doesn't.
Also, it doesn't seem to matter which Register method you use, both work only in the Page_Load (for me).</p>

<p>In my application I have a list of some objects of a medium complex class which implements <code>Comparable</code>. The <code>compareTo()</code> method's result depends on some of the fields. The method is consistent and doesn't violate the comparison contract, when the elements aren't modified during the comparison.</p>
<p>Now to the problem. The list must be sorted once in a while. But simultaneously, some items may be updated by a background task, which means that the result of <code>compareTo()</code> changes. That's where the contract may be violated.</p>
<p>I understand, that the easiest answer would be, not to update the list during the sorting at all. But it's a mobile application. It has to be responsive and the user may refresh the list whenever he wants.</p>
<p>What would be an elegant approach to this problem? Using synchronizing or some kind of lock?</p>

5,569,022 | 5,569,023 | Library file for c# dot net | <p>I'm a relatively new c#.net programmer and need some advice on adding a Library file to a c# project.</p>
<p>This project is not done in proper C# fashion and I realize that, but am not looking to solve that today.</p>
<p>I have 3 .aspx pages and each has a corresponding .cs file set up as a code behind. That all works fine.</p>
<p>Each of the .cs files has several functions that identical. I'd like to move those common functions into a common .cs file that is used by all of the .aspx pages (or the .cs files if that is how to do it) while keeping the unique code behind files for functions unique to that aspx/cs pair.</p>
<p>Once the common file is created (it already is), How do I reference that file this as simply as possible?</p>

4,830,556 | 4,830,557 | .before to insert multiple elements | <p>I have an element <code>var destination</code> which I'm trying to insert multiple elements before it. I use <code>.before</code> but I use it multiple times because I'm moving multiple elements. </p>
<p>Is there a way to improve this code, and move all the elements at once? I'm moving an element <code>moveElement</code>, the element before it, and a number of other elements that have the class <code>myClass</code> using <code>each()</code>. Any way to reduce the number of <code>destination.before()</code></p>
<pre><code>destination.before(moveElement.prev());
destination.before(moveElement);
$('div.myClass').each(function(){
destination.before($(this));
});

<p>Currently, I am constructing the array on every keypress to get the last line in the textarea. Is there a way to optimize this? Meaning, get last line in the textarea without having to construct an array.</p>
<pre><code>jQuery('#mytextarea').keypress(function() {
