A tiny asynchronous javascript loader

AsyncLoader

{
	loader = {
		queue : [],
		total : 0,
		async : function(s){
			loader.queue.push(s);
			loader.total++;
		},
		complete:function(callback){
			element = document.getElementsByTagName("script")[0];
			callback = callback instanceof Function ? callback : function(){}
			partial = function(){
				if(--loader.total == 0){
					callback();
				}
			};
			while(loader.queue.length > 0){
				tag = document.createElement("script");
				tag.type = "text/javascript";
				tag.async = true;
				tag.src = loader.queue.pop()
				tag.onload = partial;
				element.parentNode.insertBefore(tag,element);
			}
		}
	}

	// example:
	loader.async("https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js");
	loader.complete(function(){
	  if(console.debug && console.debug instanceof Function){
		console.debug($);
	  }
	});
}
