title: jQuery AJAX timeout undefined
body: <p>I was trying out example jQuery examples and to my surprise, I got an error state for an AJAX call  mentioning that timeout isn't defined. When I removed timeout attribute, it worked fine.
  I downloaded jQuery few days back, so I am pretty sure it's not a version problem.</p>
  
  <p>I was trying with Firefox(3.6.8) and not any other browser. </p>
  
  <p>Why would this occur?</p>
  
  <p><strong>Edit</strong>: Code snippet moved from the comments to the question</p>
  
  <pre><code>$.ajax({ 
    type: "GET", 
    dataType: 'json', 
    url: PHPServiceProxy, 
    timeout: 5000, 
    success: function(reply) { } // note: original code snippet provided was missing a comma here.
    error: function (xhr, textStatus, errorThrown) { } 
  });
  </code></pre>
