If you just want it for one updater, then do this:
new Ajax.Updater('foo','bar.php', {
onCreate: function(){
$('indicator').show();
},
onComplete: function(){
$('indicator').hide();
}
});
Another trick I like is this one:
new Ajax.Updater('foo','bar.php', {
onCreate: function(){
$('foo').update('alt="wait" />');
}
});
That way your update naturally wipes away the indicator, and you don't
have to manage another image in your layout.
If you want it for all the Ajax on your page, have a look at the
Prototype docs for the bit on Ajax.Responders. There's a nice recipe
there to show a global Wait indicator that comes and goes as any Ajax
on your entire page runs. I do this with a lightbox-style overlay on
the page, makes a nice effect and keeps the stray extra clicks from
happening, which was a big problem with this page.

I'm tryng to find a way for ajax.updater to show an animated gif clock
during the load of the request, but can't find it, and I don't want to
rewrite all the scripts with ajax.request. I thought I saw it in the
past, but can't recall where. Any ideas?
