Comment (by DavidAnderson):

 Snippet used for testing:

 {{{
 add_action('admin_footer', 'my_admin_footer');
 function my_admin_footer() {
         ?>
         <script>
                 jQuery(document).ready(function() {
                         wp.updates.beforeunload = function() {
 console.log("HI!"); return true; }
                 });
         </script>
         <?php
 }
 }}}

 Note that testing with alert() may not work at all - Firefox, at least,
 doesn't seem to process an alert() firing during this event.
