Sites using jquery, but there's no jquery in the code
<p>I wanted to know how sites do their animations, loading content without loading the entire page etc, so I googled for sites using jquery and found this <a href="http://docs.jquery.com/Sites_Using_jQuery" rel="nofollow">http://docs.jquery.com/Sites_Using_jQuery</a>. When I looked at the code of several sites, I dint find any one of them using methods like fadein() fadeout() or like my plain and simple code</p>

<pre><code>$.ajax({type: "POST",
url: "page.php",
data: data,
beforeSend: function(pager) {etc. etc.
</code></pre>

<p>Look at this site <a href="http://www.2minuteexplainer.com/" rel="nofollow">http://www.2minuteexplainer.com/</a> or take stackoverflow.com itself. They're all doing animations and page loading and everything else but not using fadein() fadeout() and other code like I posted above. How do they do this, and is there a way of getting a peek into their code.</p>
