title: How to de-activate (remove) the "confirm you want to leave this page" on an un-submitted form?
body: <p>I have an AJAX auto-save input fields on my page which rocks! 
  The problem is that in Safari, when the user leaves the page, he gets a warning </p>
  
  <ul>
  <li>"Are you sure you want to leave without submitting the form?"</li>
  </ul>
  
  <p>which obviously <strong>I don't want</strong>. </p>
  
  <p>How can I get rid of it!?!</p>

  <p>So the <strong>opposite</strong> of such post: <a href="https://stackoverflow.com/questions/14624843/dont-ask-confirm-if-user-submit-the-form">Dont ask confirm if user submit the form</a></p>
