Get URL Parameter in Javascript

Here is code snippet the hackish way to get url parameter in javascript, because AFAIK javascript has no built in method to get url parameter directly.

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null
}

Usage:

var name = getURLParameter("name");
console.log(name); // john
