If all you need is an easy way to asynchronous / lazy load JavaScript, you can just include something like this: http://friendlybit.com/js/lazy-loading-asyncronous-javascript/ http://friendlybit.com/js/lazy-loading-asyncronous-javascrip... Or a nice function, with "Ready" support: In <head>: <script type='text/javascript'> function ljs(s){ var a=document.createElement('script'), b=document.getElementsByTagName('script')[0]; a.type='text/javascript'; a.async=true; a.src=s; b.parentNode.insertBefore(a,b) } var Ready=[]; </script> Then anywhere in the <body> or in any included scripts you can do: Ready.push(function() { //this will get executed after all the ljs files }); Then in a script that contains your JS library, append: $.ready(function() { // or some other ondomready fn // execute all the Ready functions for (var i = 0, m = Ready.length; i < m; i++) { Ready[i](); } delete Ready; });
