A simple JavaScript function I wrote to toggle between enabling/disabling scrolling on mobile touch devices.

toggleTouchScroll.js

var toggleTouchScroll = function() {
  var d = document;
  if (typeof d.ontouchmove === 'object') return d.ontouchmove = function() {
    return false;
  };
  if (typeof d.ontouchmove === 'function') return d.ontouchmove() ? d.ontouchmove = function() {
    return false;
  } : d.ontouchmove = function() {
    return true;
  };
};
