I have a javascript widget that I wrote using jQuery 1.8 that loads on a clients website that uses jQuery 1.3. I cannot get noConflict working properly in IE without some really ugly hacks. Here is what the page looks like after my widget is rendered:
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.3.min.js"></script>
</head>
<html>
<body>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script>
$jq = $.noConflict();
</script>
</body>
</html>
In chrome, this works great, $jq is defined as jQuery 1.8.3, but in IE 8 this does not work, $jq is defined as jQuery 1.3. My guess is that its a timing issue, the script gets executed before the new jQuery is loaded. I put in some call back timers and it works, but I cant imagine having embedded callback timers is the right way to go.
Any ideas?
EDIT
I cannot namespace jQuery1.3, the client uses it throughout the page and does not want to upgrade.
I ended up going with LABjs, which is a javascript loader. This way I can synchronously load scripts and execute code on them accordingly:
