title: MooTools: How do package data for a POST ajax request?
body: <p>I'm using MooTools 1.4.1.  I want to create an ajax post requst, but I can't figure out how to construct the "data" attribute, which I wish to contain the name value pairs of a form whose id is "myForm".</p>
  
  <pre><code>        $('save').addEvent('click', function(event) {
              var req = new Request({
                  method: 'post',
                  url: 'save',
                  data: { ... },
                  onRequest: function() { 
                          // on request
                  },
                      onComplete: function(response) {
                          alert(response);
                      });
          });
  </code></pre>
  
  <p>Anyone know how I should populate the "data" attribute?  Thanks, - Dave</p>
