I am creating a little web app for the iPad and I\'ve got several elements I am preventing the user from scrolling by preventing default on the touchmove event. However, I h
document.addEventListener('touchmove', function(e){e.preventDefault()}, false);
document.getElementById('inner-scroll').addEventListener('touchmove', function(e){e.stopPropagation()}, false);
The idea is that your main scroll is always (to your discretion) disabled, but in your inner-scroll you prevent the event from bubbling up (or propagating), so it will never reach the first event listener, which would ultimately cancel the touchmove event.
I hope this is what you were looking for. I've had a situation similar to yours, where the main scroll was disabled on tablet, but i wanted an inner scroll to work. This seemed to do the job.
