JS Gets the specified parameters in the url

function GetRequest() {
	var url = location.search; // get the url string after the character "?"
	var theRequest = new Object();
	if (url.indexOf("?") != -1) {
		var str = url.substr(1);
		strs = str.split("&");
		for(var i = 0; i < strs.length; i ++) {
			theRequest[strs[i].split("=")[0]] = decodeURI(strs[i].split("=")[1]);
		}
	}
	return theRequest;
}

use:

the Request new new Object = var ();
the Request GetRequest = ();
var variable name = Request [ 'variable name to extract the URL'];
