Build a List Tree with the Beauty of jQuery

This is nothing useful, but let me show the beauty of jQuery. This snippet just adds more and more nodes on a simple UL based tree.

Here’s the HTML:

    <li><a href="#">Node 1</a></li>
    <li><a href="#">Node 2</a></li>
    <li><a href="#">Node 3</a></li>
    <li><a href="#">Node 4</a></li>

And that’s the jQuery:

var index = 5;
$('li > a').live('click', function() {
    $(this).parent().append('<ul><li><a href="#">Node ' + index + '</a></li></ul>');
    return false;

And here’s the demo.
