jquery .getScript and resource tracking
<p>rather than use something like yepnope.js is there a simple method/decent plugin that can check if a resource has previously been loaded in, if not load it?</p>

<p>I have a number of ajax calls and should I load the same form in more than once the eventlisteners are duplicated for each load (so 4th time form is loaded 4 handlers doing same thing are called). This is because it is a web service making remote calls so I use $.getScript() to include the js I need...</p>

<p>I've seen <a href="http://plugins.jquery.com/project/rloader" rel="nofollow">jquery resource loader</a> but wondered if there was any other options.</p>

<p>Thanks.</p>
