For example, my application makes use of a function similar to $$('.MyClass').each(function(element, index) { /* Do something nifty */ }); and it takes a noticeable amount of time. I'm thinking that it would be beneficial to show a loading image while $$ is processing. So I was curious if the $$ function offered any event hooks (beforeStart, afterFinish, etc) like scriptaculous events do... Does anyone think that this would work? or would the browser be locked and not animate the gif?
