scroll a full page height up or down with jQuery/Javascript

I've been fiddling with a solution to a similar problem.

All my solution does is monitor when the window scrolls.

if ($(window).scrollTop()+$(window).height()>=$("#page"+(nextpage)).offset().top+100) {

If it scrolls past the end of the "page" by more than 50px jquery animates the scroll to the next "page".

$('html, body').animate({ scrollTop: pageheight }, 500, function() { currentpage = nextpage; animatingdown = false; document.location.hash = currentpage;});

It does the same for scrolling up. This covers scrolling by mouse, keyboard or javascript.

Maybe it'll be of some use to someone (let me know if it is, or isn't).

Try this script

$(document.body).on('DOMMouseScroll mousewheel', function (e) {
        if (e.originalEvent.detail > 0 || e.originalEvent.wheelDelta < 0) {
            dir = 'down';
        } else {
            dir = 'up';
        }
        // find currently visible div :
        div = -1;
        divs.each(function(i){
            if (div<0 && ($(this).offset().top >= $(window).scrollTop())) {
                div = i;
            }
        });
        if (dir == 'up' && div > 0) {
            div--;
        }
        if (dir == 'down' && div < divs.length -1) {
            div++;
        }
        //console.log(div, dir, divs.length);
        $('html,body').stop().animate({
            scrollTop: divs.eq(div).offset().top
        }, 200);
        return false;
    });

FIDDLE DEMO

Fullscreen Demo

After having to code a page like yours, I've created a simple plugin for this kind of sites fullPage.js (Blog article)

It is in its first version. I will keep improving it as far as I can. Adding a method to be called from a menu would be nice, for example. As well as use o hastags (#) for each section, and so on. This should be done soon as I am using it in my page.

You can find more about its usage at my github account

Working in: (IE 8, Chrome, Firefox, Opera > 11, Safari, Touch devices)

I hope it helps!
