jquery - how to get value of php GET variable from address bar

Question

var c = window.location.href;
alert (c);  //  http://localhost/x1/andesignup/index.php?lang=en&cat=balls
var d = c.split('?')[1];
var e = d.split('&')[0];
var f = e.replace("lang=", "");
alert (f);  //  en

This works but is there a faster way to get value of lang.

Something like

var f = lang.value;

I'm using this:

$.urlParam = function(name) {
    var results = (new RegExp("[\\?&]" + name + "=([^&#]*)")).exec(window.location.href);
    if (results == null) return null;
    else return results[1] || 0;
};

var param = $.urlParam("action");
