How to obtain url parameters with JQuery

We'll write a quick plugin in JQuery with a little bit of our beloved REGEX to obtain the URL parameters.

(function($) {
	$.get = function(key)	{
		key = key.replace(/[\[]/, '\\[');
		key = key.replace(/[\]]/, '\\]');
		var pattern = "[\\?&]" + key + "=([^&#]*)";
		var regex = new RegExp(pattern);
		var url = unescape(window.location.href);
		var results = regex.exec(url);
		if (results === null) {
			return null;
		} else {
			return results[1];
		}
	}
})(jQuery);

Now, to use it just execute the code below

// for this url http://somehost.com/folder/?id=xx&other=param
var a = $.get("id");
var b = $.get("other");
