Execute Function After Every Digest Loop Before DOM Render

Question

I would like to execute a piece of code after every $digest loop, after the DOM has been constructed, but before the render. I want this on every $apply, not just the ones after linking/compiling. Where do I add my code?

I am not going to provide my particular use case because I would like to know how to do this in general. If you would like to help me with my particular problem, I have a separate question: Resize IFRAME to Remove Scrollbars

Answer 1

you can do $rootScope.$watch(function(){ ... }). The logic in the fn will be called every $digest loop
