<ul id='test'>
  
<li>
    
<div>
        item1
        

<script type='text/javascript'>
          alert
(0);
        
</script>
     
</div>
   
</li>
   
<li>
     item2
   

</li>
 
</ul>    
<script type = 'text/javascript'>
  $
('#test').sortable({revert: true});
</script>

in the above example you will get two alert(0) popup which is undesired in my application.
