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

Your jquery could be

$(function() {  
 $('.popuptest a').live('click', function(event) {
 $.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]);
    vars[hash[0]] = hash[1];
  }
  return vars;
},
getUrlVar: function(name){
  return $.getUrlVars()[name];
}
  });
  var second = $.getUrlVars()["param2"];
  alert(second);
  return false;
  });
});

things to note:

1. $.getUrlVars in line - var second = $.getUrlVars()["param2"];
2. this.href is replaced to $('.popuptest a').attr("href")
