Did have something called Visual Studio Runtime Redistributable installed which is just a handful of DLL's. I uninstalled it though - made no difference. Also removed entries from registry with "Visual Studio" in them, also made no difference.</p>

1,946,280 | 1,946,281 | how to get function's name from within the function (or kind of "self" reference to the function)? | <p><a href="http://stackoverflow.com/questions/251464/how-to-get-the-function-name-as-string-in-python/255297#255297">This answer</a> shows that there is a built-in <code>__name__</code> attribute of a function which can be used from <strong>outside</strong> the function, i.e. <code>print f.__name__</code>. However, how can I get this attribute from <strong>within</strong> the function itself?</p>
<p>Just using unqualified <code>__name__</code> does not help: <code>print __name__</code> prints <code>__main__</code>.</p>
<p>Using <code>print f.__name__</code> from within <code>f()</code> looks stupid - I can type <code>"f"</code> just as well.</p>
<p>Alternatively, is there a kind of <code>self</code> object for functions, i.e. can I get a pointer to the function that is executing in a common way?</p>
<p>I don't like the method proposed in <a href="http://stackoverflow.com/questions/245304/how-do-i-get-the-name-of-a-function-or-method-from-within-a-python-function-or-me">this question</a> - it feels that hacking the stack for such simple task is not the proper way. </p>
<p><strong>Motivation</strong>: I have a dictionary of <code>{keyword:function}</code>, the keywords are read from the input and an appropriate function is executed. I want each function to be executed only once, so I want each function to register itself in some data structure when executed. I know I can do it in the dictionary itself, but I thought of using a separate data structure for this.</p>

1,249,467 | 1,249,468 | Get name of prototype object | <p>I'm planning on writing a convention over configuration template source engine for KnockoutJS / MVC.

<p>My plan is use this syntax or something similar</p>
<pre><code>MyApp.EditCustomersViewModel = function() {

</code></pre>
<p>When doing this it will check the tamplate cache or fetch the templates from server using the object name as key.
The problem is I cant get the name of the prototype object, i tried this</p>
<pre><code>Object.prototype.getName = function() {
var funcNameRegex = /function (.{1,})\(/;
var results = (funcNameRegex).exec((this).constructor.toString());

<p>On the server you have structure like this </p>
<ul>
<li>Templates\ [ViewName]\index.html</li>
<li>Templates\ [ViewName]\sub-model-template.html</li>
</ul>
<p>on the client you will do </p>
<pre><code>MyApp.EditCustomersViewModel = function() {

5,511,272 | 5,511,273 | Are there any pitfalls in displaying a "No JavaScript" warning in the following fashion? | <p>I have a webpage that has a comment box that can be toggled by clicking a link (the opening and closing of the box is controlled using JavaScript, specifically JQuery). This box is hidden by default, so naturally, it's impossible to display without the use of JavaScript. I'm not concerned by this fact: the comment box is not a "necessary" feature and this is a small personal site, so I don't mind that a tiny percentage of visitors may not experience full functionality. However, I would like to display a warning if the user does not have JavaScript enabled.</p>
<p>I've considered the idea of doing this by presenting a small message (with the use of a simple HTML <code><p></code> tag) near the link that toggles the comment box, using the following bit of code:</p>
<pre><code><p class="alert" id="nojs-warning">You must have JavaScript enabled to leave a comment.</p>
</code></pre>
<p>Of course, I don't want to display this if JavaScript <em>is</em> enabled, so I have the following JQuery trigger set up to immediately hide the box when the page is loaded:</p>
<pre><code>$(function() {
$('#nojs-warning').hide();
});
</code></pre>
<p>Thus, if the user has JavaScript enabled, the event will fire and the warning will be hidden; if the user doesn't have JavaScript enabled, the event <em>won't</em> fire, and thus the warning will still be displayed.</p>
<p>For such a small, personal site, this seems like an elegant solution. Are there any pitfalls to this approach?</p>

5,568,465 | 5,568,466 | .val() not returning correct value | <p>I have the following code that runs on change for a select box:</p>

console.log("$(this).val():" + $(this).val());
if( $(this).val == 'work' ) {
// do one thing
} else {
// do something else
}
});
</code></pre>
<p>When I print out <code>console.dir($(this));</code> I can see that the selected option is set (in my screenshot example) to "work" (the label is proper case, but the actual option value is lower, so I know I'm not dealing with a case issue).</p>
<p><img src="http://i.stack.imgur.com/qdiot.png" alt="enter image description here"></p>
<p>Here's the HTML from Firebug after the select box was changed (default is "home"):</p>
<p><img src="http://i.stack.imgur.com/7iwxA.png" alt="enter image description here"></p>
<pre><code><select name="regPhoneType" id="reg-phone-type" style="display: none;" value="work">
<option value="home">Home</option>
<option value="work" selected="selected">Work</option>
<option value="cell">Cell</option>
</select>
</code></pre>
<p>So you can see that the option is correctly selected. Why, then, when in my jquery, just one line later, I call <code>console.log("$(this).val():" + $(this).val());</code>, do I get "home" instead of "work"? My understanding was that <code>.val()</code> returns the value of the selected option of a select box, so I should be getting "work".</p>
