Disable scrolling in an iPhone web application? I've tried this but it didn't work all the time, it only works sometimes then it suddenly stops and i can scroll again.

Answer 1

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

works, but make sure the body has a 100% height of the screen
