This is a dynamic javascript and css loader that is used from javascript.
It uses the document.write() technique to immediately load js and css resources.
<script type='text/javascript' src='http://rkitover.github.com/load-js/load.js'></script>
<script type='text/javascript>
// all your load calls should be in their own <script> block
load_css('http://foo.com/some.css')
load_js('/js/some.js')
// will not be loaded twice!
load_js('/js/some.js')
load_jquery() // latest 1.x, only if window['jQuery'] is unset
load_jquery('1.8.6') // specific version
load_jquery_ui() // loads jquery first, uses jquery-ui 1.10.3 by default, only if jQuery.ui is unset
load_jquery_ui('1.9.2') // specific version
</script>
<script type='text/javascript'>
// stuff loaded in preceding <script> block immediately usable from the next!
$('<div>').append('Yay!').dialog({ modal: true })
</script>
