Disable scrolling in all mobile devices

html, body {
  overflow-x: hidden;
}
body {
  position: relative;
}

The position relative is important, and i just stumbled about it. Could not make it work without it.

cgvector answer didn't work for me, but this did:

document.body.addEventListener('touchstart', function(e){ e.preventDefault(); });

I wouldn't leave it just like that, a smarter logic is needed to select when to prevent the scrolling, but this is a good start.

Taken from here: Disable scrolling in an iPhone web application?

For future generations:

To prevent scrolling but keep the contextmenu, try

document.body.addEventListener('touchmove', function(e){ e.preventDefault(); });

It still prevents way more than some might like, but for most browsers the only default behaviour prevented should be scrolling.

For a more sophisticated solution that allows for scrollable elements within the nonscrollable body and prevents rubberband, have a look at my answer over here:
