I have a div which has its content changing all the time , be it ajax requests, jquery functions, blur etc etc.
ajax requests
jquery functions
blur
Is there a way
You are looking for MutationObserver or Mutation Events. Neither are supported everywhere nor are looked upon too fondly by the developer world.
If you know (and can make sure that) the div's size will change, you may be able to use the crossbrowser resize event.
