$.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];
  }
});

//Second call with this:
// Get object of URL parameters
var allVars = $.getUrlVars();

// Getting URL var by its nam
var byName = $.getUrlVar('name');
