>From a semantic/accessibility point of view you would ideally add and
remove the activity indicators to/from the DOM when they are needed.
However if there are parts of your application were accessibility is
not much of a concern like the back end, I think it's excusable to go
for the quick & dirty way ; ).

Thanks for the heads up Felix. I really understand your point.
Would it make sense then to drop in a div into the html layout and then
dynamically add the the image as needed or do you suggest doing both on
the fly?

One thing I really hate about AJAX, is that everybody put's those
semantically meaningless activity indicators in their html layout. When
you disable css you end up with a mess of animated gif's which is
really annoying. I don't blame you, but it's a very nice move towards
accessibility and usability to add those div's/images/etc. with
_javascript_ to your DOM instead of having them there already and just
hiding them with CSS.

Man, that is REALLY powerful John. I added a .hide() method like this:
$("#throbber").hide()
.ajaxStart(function(){
$(this).show();
})
.ajaxStop(function(){
$(this).hide();
});
and then added my div like this:
<div id="throbber"><img src="" width="16"
height="16" alt="" border="0" /></div>
and it worked like a charm!
Thanks for your help and patience John.

jQuery's system is more dynamic than just hiding/showing a single
element, as you can see. Let me know if this helps you at all.

I've seen some Ajax libraries that have an Ajax throbber/indicator
function built in which allows you to specify an indicator during the
Ajax call.
Does JQuery have something like this? If not, whats everyone doing to
display one? Any plugins for this?
