i am trying to change color of the list on clicking anchor tag using jquery. On clicking the anchor tag i have called a C# function code behind.. if i give return false code in jquery like the below code the color has changed. but code behind function is not working. once i comment return false from jquery the code behind code is working but the color has not changed.

html code :

<ul class="ullist" id="navlist">

    <li id="list1"><a id="a1"  runat="server" >Active</a></li>

 <li id="list2"><a id="a2"  runat="server" >Abeyance</a></li>

</ul>

Jquery Code :

$(document).ready(function () {

    $("a").click(function () {

       $("li.active1").removeClass("active1");

                   $(this).parent('li').addClass('active1');

       return false;
   });

});
