jQuery: Numbering an Unordered List

Here’s a very simple script which adds numbers sequentially to an unordered list using jQuery
Let us assume you have an unordered list as shown below:




To add numbers to it sequentially, use this code:

<script type="text/javascript"
src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.1.min.js">
</script> 
<script type="text/javascript">
    $(function () {
        $('ul > li').each(function () {
            $(this).prepend("(" + 
                ($(this).index() + 1) + ") ");
        });
    })
</script>

As you can see, we are using the jQuery Prepend function to insert numbers to the beginning of each element in the set of matched elements.
