Continuous Looping Page (Not Infinite Scroll)

Question

I'm looking for resources that create scrolling functions like the ones found on these sites:
Outpost Journal
Unfold

Once the scroll bar hits the bottom of the page, I want it to loop back to the top. I'm familiar with with the infinite scroll, and this is not what I want. I've also found scripts that will write/add the same content to the bottom of the page, but none that loop back to the top of the page.

Answer 1

Try this:

   $('document').ready(function() {
             $(document).scroll(function(){
             if(document.documentElement.clientHeight + 
             $(document).scrollTop() >= document.body.offsetHeight )$(document).scrollTop(0);
             });
          }); 

Answer 2

if you want infinite scroll in both directions use

if (document.documentElement.clientHeight + $(window).scrollTop() >= $(document).height()) {
    $(document).scrollTop(0)
} else if ($(window).scrollTop() < 0) {
    $(document).scrollTop($(document).height())
}
