Get query string values from Javascript

So now I am writing here utility function that i am using to get query string values.

Just Passe the query string name and function will return value.


function queryString(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(window.location.href);
if (results == null) return "";
else { var x = results[1]; return x.replace(/%20/gi, ' '); }
}
