How can I tell if a page has jumped to the anchor (#) in javascript?

Question

I have some javascript that can appear on many different pages. Sometimes those pages have been accessed via a URL containing an anchor reference (#comment-100, for instance).

Seems like you could use window.onscroll. I tested this code just now:

which seems to work.

Edit: Hm, it doesn't work in IE8. It works in both Firefox and Chrome though.

Edit: jQuery has a .scroll() handler, but it fires before scrolling on IE and doesn't seem to work for Chrome or Firefox.
