Get Query string values using JavaScript

You don't need jQuery for that purpose. You can use just some pure JavaScript:

function getParameterByName(name) {

    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");

    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),

        results = regex.exec(location.search);

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

}

Usage:

Suppose your borwser url is: https://www.facebook.com/sharepointTipsTricks?location=india

var Location = getParameterByName('location');   // Location = india
