Is it possible using scriptaculous/prototype to watch out for any happening Ajax activity, and do something like show/hide a spinner gif to indicate to the user that there is activity taking place in the backgound?

I think I first saw this code on this list, and I think the
Ajax.Responders code is fairly new in Prototype:
Ajax.Responders.register({
onCreate: function() {
if($(''busy'') && Ajax.activeRequestCount>0)
Effect.Appear(''busy'',{duration:0.5,queue:''end''});
},
onComplete: function() {
if($(''busy'') && Ajax.activeRequestCount==0)
Effect.Fade(''busy'',{duration:0.5,queue:''end''});
}
});

Oh neat, I hadn''t noticed that either... I''d implemented something similar, as I''m sure many others have, but as my own wrapper around the Ajax.Request and Ajax.Updater calls. The only interaction issue I wanted to raise was that for Ajax.Updater calls it might make sense to be able to get the name of the div to the responder. For example, when I have some link that fires an ajax call to update an area of the screen, I put a slightly transparent overlay on top of that div while the request is happening (like the In-Place-Editor does). That seemed to me to be an enhancement on the notification to the user - as it shows exactly what area of content is being changed during the process (an Effect.Highlight afterwards didn''t seem to cover the cases I needed it too). Anyway, it looks like the responder callback doesn''t handle that (since it''s at a lower level): responder[callback].apply(responder, [request, transport, json]); Thoughts?
