Give them a class name that is consistent then you can do:

    $(&#39;table td.classname&#39;)


To get the ones you want.

I&#39;m trying to start writing unit tests for django and I&#39;m having some questions about fixtures:

I made a fixture of my whole project db (not certain application) and I want to load it for each test, because it looks like loading only the fixture for certain app won&#39;t be enough.

I&#39;d like to have the fixture stored in `/proj_folder/fixtures/proj_fixture.json`.

I&#39;ve set the `FIXTURE_DIRS = (&#39;/fixtures/&#39;,)` in my settings.py.
Then in my testcase I&#39;m trying 

    fixtures = [&#39;proj_fixture.json&#39;]

but my fixtures don&#39;t load.
How can this be solved?
How to add the place for searching fixtures?
In general, is it ok to load the fixture for the whole test_db for each test in each app (if it&#39;s quite small)?
Thanks!

How can I check that nginx is serving the .gz version of static files, if they exist?

I compiled nginx with the gzip static module, but I don&#39;t see any mention of the .gz version being served in my logs. (I have minified global.js and global.css files with .gz versions of them in the same directory).

The relevant part of nginx.conf looks like this:

    gzip  on;
    gzip_static on;
    gzip_http_version 1.0;
    gzip_disable &quot;MSIE [1-6]\.&quot;;
    gzip_vary on;

    gzip_comp_level 2;
    gzip_proxied any;
    gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;


Any pointers would be appreciated.

I have an html table with many rows.  I&#39;m currently grouping several rows inside a div (I know this is ugly) and then show or hide the divs to show or hide the rows inside it.  Is there a standard way to do this. Something like rowgroup or multiple tbody instead of this ugly div grouping?

I have recently noticed that a lot of JavaScript files on the Web start with a `;` immediately following the comment section.

For example, [this jQuery plugin&#39;s](http://plugins.jquery.com/project/ScrollTo) code starts with:

	/**
	 * jQuery.ScrollTo
	 * Copyright (c) 2007-2008 Ariel Flesler - aflesler(at)gmail(dot)com | http://flesler.blogspot.com
	 * Dual licensed under MIT and GPL.
	 * Date: 9/11/2008										
	 .... skipping several lines for brevity...
	 *
	 * @desc Scroll on both axes, to different values
	 * @example $(&#39;div&#39;).scrollTo( { top: 300, left:&#39;+=200&#39; }, { axis:&#39;xy&#39;, offset:-20 } );
	 */
	;(function( $ ){


Why does the file need to start with a `;`? I see this convention in server-side JavaScript files as well.

What are the advantages and disadvantages of doing this?

While debugging jQuery apps that use AJAX, I often have the need to see the json that is being returned by the service to the browser.  So I&#39;ll drop the URL for the JSON data into the address bar.

This is nice with ASPNET because in the event of a coding error, I can see the ASPNET diagostic in the browser: 

![alt text][1]

But when the server-side code works correctly and actually returns JSON, IE prompts me to download it, so I can&#39;t see the response. 

![alt text][2]

**Can I get IE to NOT do that, in other words, to just display it as if it were plain text?**

I know I could do this if I set the Content-Type header to be `text/plain`.  

But this is specifically an the context of an ASPNET MVC app, which sets the response automagically when I use JsonResult on one of my action methods.  Also I kinda want to keep the appropriate content-type, and not change it just to support debugging efforts.

Is there an easy and straight-forward method to select elements based on their `data` attribute?  For example, select all anchors that has data attribute named `customerID` which has value of `22`.  

I am kind of hesitant to use `rel` or other attributes to store such information, but I find it much harder to select an element based on what data is stored in it.

I am going to create an XML element in JavaScript to exchange data with server side. I found I can do it with `document.createElement`. But I do not know how to convert it to string. Is there any API in browser to make it easier? Or is there any JS library including this API?

**EDIT:** I found that browser API XMLSerializer, it should be the right way to serialize to string.

In the 1990s, there was a fashion to put Javascript code directly into `&lt;a&gt;` href attributes, like this:

    &lt;a href=&quot;javascript:alert(&#39;Hello world!&#39;)&quot;&gt;Press me!&lt;/a&gt;

And then suddenly I stopped to see it. They were all replaced by things like:

    &lt;a href=&quot;#&quot; onclick=&quot;alert(&#39;Hello world!&#39;)&quot;&gt;Press me!&lt;/a&gt;

For a link whose sole purpose is to trigger Javascript code, and has no real `href` target, why is it encouraged to use the `onclick` property instead of the `href` property?

Why is it bad practice to use links with the javascript: &quot;protocol&quot;?

When I refresh a page with Firefox, the values of the check boxes, input fields, etc. are kept.

Is there a way to make Firefox not keep them, using a meta tag without JavaScript?






Preventing Firefox from remembering the input value on refresh with a meta tag

I have had this problem with every web page I have created.  There is always a top margin above the &#39;main container&#39; div I use to place my content in the center of the page.  I am using a css style sheet and have set margins and padding in the body to 0px and set the margin and padding to 0 in the div:  

    body{
        margin-top: 0px; 
        margin-bottom: 0px; 
        margin-left: 0px; 
        margin-right: 0px;
        padding: 0;
        color: black; 
        font-size: 10pt; 
        font-family: &quot;Trebuchet MS&quot;, sans-serif;
        background-color: #E2E2E2;
    }

    div.mainContainer{
        height: auto; 
        width: 68em;
        background-color: #FFFFFF;
        margin: 0 auto; 
        padding: 0;
    }


I have looked online many times, but all I can see to do is set these margin and padding attributes.  Is there something else I should be doing?  The margin exists in IE and Firefox.

Here is a more thorough look at the code (it is in the beginning stages of creation, so there isn&#39;t much in it...)

How do I remove the top margin in a web page?

I need to find which event handlers are registered over an object.

For example:

    $(&quot;#el&quot;).click(function() {...});
    $(&quot;#el&quot;).mouseover(function() {...});

`$(&quot;#el&quot;)` has *click* and *mouseover* registered.

Is there a function to find out that, and possibly iterate over the event handlers?

If it is not possible on a jQuery object through proper methods, is it possible on a plain DOM object?

jQuery find events handlers registered with an object

Is there any way to get the collection of all `textNode` objects within a document? 

`getElementsByTagName()` works great for Elements, but `textNode`s are not Elements.

**Update:** I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I was hoping there was some browser-native way to do it. After all it&#39;s a little strange that I can get all the `&lt;input&gt;`s with a single built-in call, but not all `textNode`s.

getElementsByTagName() equivalent for textNodes

I&#39;ve got a script that inserts some content into an element using `innerHTML`.

The content could for example be:

    &lt;script type=&quot;text/javascript&quot;&gt;alert(&#39;test&#39;);&lt;/script&gt;
    &lt;strong&gt;test&lt;/strong&gt;

Problem is that the code inside the `&lt;script&gt;` tag doesn&#39;t get executed.
I googled it a bit but there were no apparent solutions. If I inserted the content using jQuery `$(element).append(content);`the script parts got `eval`&#39;d before being injected into the DOM.

Has anyone got a snippet of code that executes all the `&lt;script&gt;` elements? The jQuery code was a bit complex so I couldn&#39;t really figure out how it was done.

**Edit**:

By peeking into the jQuery code I&#39;ve managed to figure out how jQuery does it, which resulted in the following code:

    Demo:
    &lt;div id=&quot;element&quot;&gt;&lt;/div&gt;
    
    &lt;script type=&quot;text/javascript&quot;&gt;
      function insertAndExecute(id, text)
      {
        domelement = document.getElementById(id);
        domelement.innerHTML = text;
        var scripts = [];
      
        ret = domelement.childNodes;
        for ( var i = 0; ret[i]; i++ ) {
          if ( scripts &amp;&amp; nodeName( ret[i], &quot;script&quot; ) &amp;&amp; (!ret[i].type || ret[i].type.toLowerCase() === &quot;text/javascript&quot;) ) {
      			scripts.push( ret[i].parentNode ? ret[i].parentNode.removeChild( ret[i] ) : ret[i] );
      		}
        }
      
        for(script in scripts)
        {
          evalScript(scripts[script]);
        }
      }
      function nodeName( elem, name ) {
      	return elem.nodeName &amp;&amp; elem.nodeName.toUpperCase() === name.toUpperCase();
      }
      function evalScript( elem ) {
      	data = ( elem.text || elem.textContent || elem.innerHTML || &quot;&quot; );
    
        var head = document.getElementsByTagName(&quot;head&quot;)[0] || document.documentElement,
      	script = document.createElement(&quot;script&quot;);
      	script.type = &quot;text/javascript&quot;;
      	script.appendChild( document.createTextNode( data ) );
      	head.insertBefore( script, head.firstChild );
      	head.removeChild( script );
    
      	if ( elem.parentNode ) {
      		elem.parentNode.removeChild( elem );
      	}
      }
    
      insertAndExecute(&quot;element&quot;, &quot;&lt;scri&quot;+&quot;pt type=&#39;text/javascript&#39;&gt;document.write(&#39;This text should appear as well.&#39;)&lt;/scr&quot;+&quot;ipt&gt;&lt;strong&gt;this text should also be inserted.&lt;/strong&gt;&quot;);
    &lt;/script&gt;

Executing &lt;script&gt; elements inserted with .innerHTML

It bugs me that I can&#39;t just do `document.querySelectorAll(...).map(...)` even in Firefox 3.6, and I still can&#39;t find an answer, so I thought I&#39;d cross-post on SO the question from this blog:

http://blowery.org/2008/08/29/yay-for-queryselectorall-boo-for-staticnodelist/

Does anyone know of a technical reason why you don&#39;t get an Array?  Or why a StaticNodeList doesn&#39;t inherit from an Array in such a way that you could use `map`, `concat`, etc?

(BTW if it&#39;s just one function you want, you can do something like `NodeList.prototype.map = Array.prototype.map;`...but again, why is this functionality (intentionally?) blocked in the first place?)

Why does document.querySelectorAll return a StaticNodeList rather than a real Array?

I generate the numbering of my headers and figures with CSS&#39;s `counter` and `content` properties:

    img.figure:after {
      counter-increment: figure;
      content: &quot;Fig. &quot; counter(section) &quot;.&quot; counter(figure);
    }

This (appropriate browser assumed) gives a nice labelling &quot;Fig. 1.1&quot;, &quot;Fig. 1.2&quot; and so on following any image.

*Question:* How can I access this from Javascript? The question is twofold in that I&#39;d like to access *either* the current value of a certain counter (at a certain DOM node) *or* the value of the CSS generated content (at a certain DOM node) *or*, obviously, both information.

*Background:* I&#39;d like to append to links back-referencing to figures the appropriate number, like this:

    &lt;a href=&quot;#fig1&quot;&gt;see here&lt;/h&gt;
    ------------------------^ &quot; (Fig 1.1)&quot; inserted via JS

As far as I can see, it boils down to this problem:
I *could* access `content` or `counter-increment` via `getComputedStyle`:

    var fig_content = window.getComputedStyle(
                        document.getElementById(&#39;fig-a&#39;),
                        &#39;:after&#39;).content;

However, this is not the *live* value, but the one declared in the stylesheet. I cannot find any interface to access the *real* live value. In the case of the counter, there isn&#39;t even a real CSS property to query.


**Edit:** Digging deeper and deeper through the DOM specs, I found [the DOM Level 2 Style Counter interface](http://www.w3.org/TR/DOM-Level-2-Style/css.html#CSS-Counter). This seems to a) allow access to the current counter value and b) be implemented in Firefox, at least. However, I have no idea on how to use it. My current approach died tragically after this Firebug output:

    // should return a DOM 2 Counter interface implementation...
    window.getComputedStyle(fig_a_element, &#39;:after&#39;)
          .getPropertyCSSValue(&quot;counter-increment&quot;)[0]
          .getCounterValue();

    [Exception... &quot;Modifications are not allowed for this document&quot; code: &quot;7&quot;
     nsresult: &quot;0x80530007 (NS_ERROR_DOM_NO_MODIFICATION_ALLOWED_ERR)&quot;
     location: &quot;http://localhost/countertest.html Line: 71&quot;]

Any idea, how this could be brought to life would be highly appreciated.

**Edit 2:** Apparently I misinterpreted the Counter object of DOM Level 2 Style. It, too, has no property to return the current counter value. This makes the above approach invalid.

New approach: Is there a possibility to read the content of a pseudo-element via the DOM? That is, can I select the pseudo-element (`treeWalker` comes to mind) and then get its `nodeValue`? (If you start to type *&#39;jQuery&#39;* now, please reconsider to change that term into *&#39;Sizzle&#39;*...)
