I thought to write a simple example to show a progress bar or a gif image showing a that a task is happening at the background using a jquery function.
i) Include jquery script file in the header section and the following code in the head
<script language="javascript">
$(document).ready(function(){
$('#progress').hide();
$("#main a.bgdiv").click(function(){
$("#progress").show("slow");
$("body").load($(this).attr('href'));
return false;
});
});
</script>
