[jQuery] Display GIF animation during jQuery loop

[Borax]

Hi,

I have a probably basic problem.
I actually want to display a simple GIF animation during a jQuery
function which actually takes a few seconds to run.

Basically, I do :

  $('IMG.my_gif_animation').show();
  try {
    $('...').each(function() { ... }); // which takes a few seconds
  } finally {
    $('IMG.my_gif_animation').hide();
  }

My problem is simple : the GIF image is correctly displayed but as
soon as the jQuery loop starts, GIF animation is stopped !
Any hint would be welcome...

Thanks,
Thierry
