Javascript - Get Query String for current page as object

Here is a code snippet that gets the current query string parameters and puts them into a query object that can then be used to read the values in subsequent code.

	(function (window) {
	//declare the variables here,
	//as js variable hoisting will do this
	//here anyway
	var m, queryString, re;
	//if the window query object does not exist
	if (!window.query) {
	//create it
	window.query = {};
	//get the query string (without the #)
	queryString = location.search.substring(1);
	//declare the regex
	re = /([^&=]+)=([^&]*)/g
	//execute the regex for each query parameter
	while (m = re.exec(queryString)) {
	//add the query parameter to the query object
	window.query[decodeURIComponent(m[1])] = decodeURIComponent(m[2]);
	}
	}
	}(window));
