Helps with messing with URLs and grabbing their query vars.

jquery.getLocationObj.js

$.getLocationObj = function(url) {
	var query, match,
		a = document.createElement('a'),
		pl = /\+/g,  // Regex for replacing addition symbol with a space
		search = /([^&=]+)=?([^&]*)/g,
		decode = function (s) { return decodeURIComponent(s.replace(pl, " ")); },
		urlParams = {},
		b = {};

	a.href = url;
	query  = a.search.substring(1);

	while (match = search.exec(query)) {
		urlParams[decode(match[1])] = decode(match[2]);
	}
	
	a.var = urlParams;

	return a;
}

// Usage
var url = $.getLocationObj('http://mattfelten.com/test/?var1=test&var2=test2');

// url.origin = http://mattfelten.com
// url.pathname = /test/
// url.var.var1 = test
// url.var.var2 = test2
