<script>$(function(){
$("button:first").click(function(){
$("#aja").load("ajax.html");});
$("button:last").click(function(){
$("#aja").remove();});
});
</script>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

<body>
<button>Load page</button><button id="rem">Remove ajax content</button>
<div id="aja"></div>

and ajax.html code

<body>
<script>$(function(){
cool();});
function cool(){
$("button:last").after("Hello");
setTimeout("cool()",10000);}
</script>
</body>

Now when i load ajax.html it cool() function runs and keeps on adding hello to last button .The problem is when i remove the ajax loaded content with second button,cool() function which is removed keeps on running .But i want the cool function to stop after removal of ajax content

    Checking on existence of #aja block may help:

    function cool() {
    if ($("#aja").length == 0) return;

    $("button:last").after("Hello");
    setTimeout("cool()", 10000);
}
