javascript - $(document).scrollTop() always returns 0

Question

I'm simply trying to do something once the scroll position of the page reaches a certain height. However scrollTop() is returning 0 or null no matter how far down I scroll. This is the help function I'm using to check the scrollTop() value:

$('body').click(function(){
    var scrollPost = $(document).scrollTop();
    alert(scrollPost);
});

I've tried attaching scrollTop() to $('body'), $('html') and of course $(window), but nothing changes.

Any ideas?

Answer 1

For some reason, removing 'height: 100%' from my html and body tags fixed this issue.

I hope this helps someone else!
