Won't fade out?

Won't fade out?

I have created a javascript function to make a message fade out in my clients panel.

Here is my function:

  2. function deletemsg(id)
  3. {
  4. $.ajax({ url: "ajax_deletemsg.php?id=" + id, context: document.body, success: function(){
  5. $('#msg-' + id).fadeOut(1000, function() {
  6. // Animation complete.
  7. alert("faded");
  8. $('#msg-' + id).remove();
  9. });
  10.   }});
  11. }
It shows the 'faded' alert message but it doesn't fade the area? How can I fix this?
