detect distance scrolled from top jquery

Question

How can I detect the number of pixels scrolled in a browser window? I need this to dynamically adjust the height of a 100% height div...

I'm using jQuery.

EDIT: I cannot just use scrollTop() because I'm working with a 100% height div with overflow set to auto. Firefox does not detect browser scrolling due to this, the only thing scrolling is a 100%x100% div...

Answer 1

use $(document).scrollTop() :

$(document).scroll(function() {     console.log($(document).scrollTop()); })
