Example:

<UL>
   <LI>First Item</LI>
   <LI>Second Item</LI>
   <LI>Third Item</LI>
   <LI>Fourth Item</LI>
</UL>

on click of a button, i will need to add a new LI element as the first element in the UL, which would look like the below

<UL>
   <LI>New Item is here</LI>
   <LI>First Item</LI>
   <LI>Second Item</LI>
   <LI>Third Item</LI>
   <LI>Fourth Item</LI>
</UL>

Answer 1

$("ul").prepend("<li>New Item is here</li>");

Answer 2

<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
<script language="javascript">
function example_append() {
   $("ul").prepend("<li>New Item is here</li>");
}
</script>
<input type="button" value="Append" onclick="example_append()" /><br/>
<ul>
   <LI>First Item</LI>
   <LI>Second Item</LI>
