title: Recommendation for a jquery plugin for dirty forms - Notify user that changes will be lost when exiting page
body: <p>I'm looking for a way to notify our users not to leave a page if the form-data was changed without saving. A warning message should appear (with the option to leave anyways or stay at the page). We're using jquery and jquery-ui, so I'd like to use a jquery plugin (optionally with a jquery-ui dialog).</p>
  
  <p>Saw several options ( <a href="https://github.com/acvwilson/dirty_form" rel="nofollow">https://github.com/acvwilson/dirty_form</a>, <a href="https://github.com/snikch/jquery.dirtyforms" rel="nofollow">https://github.com/snikch/jquery.dirtyforms</a>), but since <a href="http://plugins.jquery.com" rel="nofollow">http://plugins.jquery.com</a> is down now, I am wondering if I missing anything else?</p>
  
  <p>Any other recommendations?</p>
