two ways to grab querystrings using pure js

retrieving querystring values

function splitURL(){
	var query = window.location.search.substring(1),
		vars = query.split("&"),
		params = {},
		p;

	for (var i=0; i<vars.length;i++){
		p = vars[i].split("=");
		params[ p[0] ] = p[1];
	};

	return params;
};



function regexURL(){
	var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
		results = regex.exec(window.location.search);

	return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
};
