scroll - Javascript: check IF page is at the top

Question

Is there a way to check, with JavaScript, if the page is at scroll(0,0)?

Reason being I've got a full page slider that I need to pause the second the page is not at origin.

And it might not necessarily be because the page is being scrolled live as I've got internal HTML # links that would load the page right to a scrolled point without actually scrolling.

So the check needs to be is the page not at the top, as opposed to, has the page been scrolled.

Try this:

document.body.scrollTop === 0
