};Given a querystring (as a string), deserializes it to a javascript object.
$.deparam = function (queryString) {
if (typeof queryString != "string") {

}Remove “?”, which starts querystrings
if (queryString && queryString.charAt(0) == "?") {

$.parseQueryString = $.deparam;Gets the querystring from the current document.location as a javascript object.
$.currentQueryString = function () {

};Given a url (pathname) and an object representing a querystring, constructs a full URL
$.appendQueryString = function (url, parsedQueryString) {
var qs = $.param(parsedQueryString);
if (qs.length > 0) {
