If you just want to get/set a cookie temporarily here's one way to do it:

function SetCookie(name, value) {
	// lasts as long as the browser is open
	document.cookie = name + "=" + escape(value);
}

function GetCookie(name) {
	var result = null;
	var theCookie = " " + document.cookie + ";";
	var searchName = " " + name + "=";
	var startOfCookie = theCookie.indexOf(searchName);
	var endOfCookie;
	
	if (startOfCookie != -1) {
	
		startOfCookie += searchName.length;
		endOfCookie = theCookie.indexOf(";", startOfCookie);
		result = unescape(theCookie.substring(startOfCookie, endOfCookie));
	}
	return result;
}
