Hi all, I have written some jQuery but the slideUp is not working. If I use alert('Saved'); as the success then it works but slide up isn't...any ideas?

Code JavaScript:
     <script>
         $(document).ready(function(){
         $('#productAddRightCol ul li').click(function(){
 
            $.ajax({
              type: "POST",  
              url: "/admin/adminincludes/delete_accessories.php",
              success: function(){
                  $(this).slideUp();
              }
            });
 
         });
 
         });
     </script>
