defer parsing of jquery

Hi All,
I am using below js code for jquery defer parsing.
Here is my code:
<script type=”text/javascript”>

function downloadJSAtOnload() {
var element = document.createElement(“script”);
element.src = “jquery-1.3.2.js”;
document.body.appendChild(element);

/*
$(document).ready(function(){
$(“a”).addClass(“test”);

});
*/

}

// Check for browser support of event handling capability
if (window.addEventListener)
window.addEventListener(“load”, downloadJSAtOnload, false);
else if (window.attachEvent)
window.attachEvent(“onload”, downloadJSAtOnload);
else window.onload = downloadJSAtOnload;

</script>

How can call $(document).ready for the above code?
Please help me asap…

Thanks in advance …
