title: jQuery .submit() success or failure trigger
body: <p>I am using <code>.submit()</code> to submit my form over ajax periodically, but I want the user to see that the form is being saved with a spinning wheel and then 'Saved!' upon success. Is there a <code>success</code> trigger for <code>.submit()</code> in jQuery?</p>
  
  <p>Thanks!</p>
