The following is for setting up jQuery and using document and window load events to do something.
<html>
<head>
//USE ONLY 1 jQuery CDN
//Google jQuery CDN
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
//jQuery CDN
<script src="//code.jquery.com/jquery-1.10.2.min.js"></script>
//ASPNET jQuery CDN
<script src="//ajax.aspnetcdn.com/ajax/jquery/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
$(window).ready(function()
{
//fired when all page is fully loaded including images
});
$(document).ready(function()
{
//fires when DOM is ready
//grab an object by Id and show it (it is was hidden)
$("#objectId").show();
//grab an object by class and show it (it is was hidden) - will affect all objects with the specified class
$(".myClass").show();
});
</script>
</head>
<body>
</body>
</html>
