ajaxQueue.js

---

About

ajaxQueue's main purpose is to limit the number of ajax requests sent at any one moment.
When requests become completed, the next ajax request in the queue will be fired.

Usage

Requires JQuery, tested on 1.7.2, to use add the following script src into your webpage:

<script src="ajaxQueue.js"></script> 

and declare a variable:

var ajaxQueue1 = $.ajaxQueue();
ajaxQueue1.add({
	url: "http://url.com",
	type: "GET"
});

Additional examples for initializing

var ajaxQueue1 = $.ajaxQueue({
	max : 5; //Sets the maximum number of in-transit ajax requests
	id : "SOMEID"; //Sets the id of the variable; works with [a-zA-Z0-9]+
	timeout : 50; //Sets how often we should poll the queue for firing out.
});

Additional Points:

//ajaxQueue1.add( obj ) and ajaxQueue2.add( obj2 ) will both add to the same queue
var ajaxQueue1 = $.ajaxQueue();
var ajaxQueue2 = $.ajaxQueue(); 

//ajaxQueue3.add( obj ) and ajaxQueue4.add( obj2 ) will both add to the same queue
//as they have the same id.
var ajaxQueue3 = $.ajaxQueue({
	id: "X"
});
var ajaxQueue4 = $.ajaxQueue({
	id: "X"
});

###Program Notes### Due to the inherent limitation of javascript single threaded-ness, browsers may fire off ajax requests at poorly timed intervals.

Author Notes

My first plugin, I needed an ajax queuer for pages with thousands of ajax requests.
