Question

I’m trying to figure out how to, upon pageload, automatically scroll to the bottom of a page (which has been described sufficiently here) and then scroll back up automatically upon reaching the bottom of the page. I can find the automatic scrolling to the bottom, but I can’t figure out how to identify when I’m at the bottom of the page, and how to scroll back up when I am. I’d do this using generic Javascript (or JQuery).

Thanks in advance!

Try this:
http://jsfiddle.net/yjYJ4/

$('html, body').animate({ scrollTop: $(document).height() - $(window).height() }, 1000, function() {
    $(this).animate({ scrollTop: 0 }, 1000);
});

You can view the demo in full screen here: http://jsfiddle.net/yjYJ4/embedded/result/

Change the number “1000” if you want to increase or decrease speed.

Works fine in Chrome, Firefox and IE 6-9.

EDIT:

If you need it to repeat forever (not recommended…) you could do like this: http://jsfiddle.net/QUCWe/
