Functions for obtain get parameters

Functions for obtain get parameters

While I was searching how to obtain GET parameters from the URL using only Javascript, I found this code. But I don't remember the source of it.

$.extend({
 getUrlVars: function(){
  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;
 },
 getUrlVar: function(name){
  return $.getUrlVars()[name];
 }
});
