How to get querystring from URL using jQuery

Question

I have the following URL:

http://www.edureka.co/?location=mylocation1

I need to get the value of location from the URL into a variable and then use it in jQuery code:

var thequerystring = "getthequerystringhere"

$('html,body').animate({scrollTop: $("div#" + thequerystring).offset().top}, 500);

How can I grab that value using JavaScript or jQuery?

Hello @Kartik,

The following code will return a JavaScript Object containing the URL parameters:

// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

For example, if you have the URL:

http://www.example.com/?me=myValue&name2=SomeOtherValue

This code will return:

{
    "me"    : "myValue",
    "name2" : "SomeOtherValue"
}

and you can do:

var me = getUrlVars()["me"];
var name2 = getUrlVars()["name2"];

Hope it helps!!

Thank You!!
