jQuery: How to get parameters of a url?

Question

New to jQuery and I\'m having trouble getting the parameters of a url that my server generates. I have a url like this:

Answer 1

Using code below for some time, but recently discoverd a problem with an base64_encode string in the URL, having == at the end, like: /index.php?a=1&b=2&c=Mw==&d=4.

Using getUrlVar("c") gives me 'Mw' as result, but this should be 'Mw==', so added an extra line:

 $.extend({
  getUrlVars: function(){
   var vars = [], hash;
   var hashes = $('.popuptest a').attr("href").slice($('.popuptest a').attr("href").indexOf('?') + 1).split('&');
   for(var i = 0; i < hashes.length; i++)
   {
    hash = hashes[i].split('=');
    vars.push(hash[0]);
    if (hash.length > 2) hash[1] = hash.slice(1).join('=');
    vars[hash[0]] = hash[1];
   }
   return vars;
  },
  getUrlVar: function(name){
   return $.getUrlVars()[name];
 }
});
