javascript: detect scroll end

I have a div layer with overflow set to scroll.

When scrolled to the bottom of the div, I wanna run a function.

The accepted answer was fundamentally flawed, it has since been deleted. The correct answer is:

function scrolled(e) {
  if (myDiv.offsetHeight + myDiv.scrollTop >= myDiv.scrollHeight) {
    scrolledToBottom(e);
  }
}

Tested this in Firefox, Chrome and Opera. It works.

I could not get either of the above answers to work so here is a third option that works for me! (This is used with jQuery)

if (($(window).innerHeight() + $(window).scrollTop()) >= $("body").height()) {
    //do stuff
}

Hope this helps anyone!
