Disable overscroll in iOS Safari

How can I prevent overscroll in Safari iOS? I would use the touch gesture for navigate on a site but I can't.

I tried this:

$(window).on('touchstart', function(event) {

    event.preventDefault();

});

But in this way I disabled all gesture, infact I can't zooming with pinch-in and pinch-out.

Any solutions? Thanks.

This Should be the easiest way to accomplish this:

$(function() {
    document.addEventListener("touchmove", function(e){ e.preventDefault(); }, false);
});

Hope this helps.

Best.

This way will allow scrollable elements while still preventing the overscroll in the browser itself.

//uses document because document will be topmost level in bubbling
$(document).on('touchmove',function(e){
  e.preventDefault();
});
//uses body because jquery on events are called off of the element they are
//added to, so bubbling would not work if we used document instead.
$('body').on('touchstart','.scrollable',function(e) {
  if (e.currentTarget.scrollTop === 0) {
    e.currentTarget.scrollTop = 1;
  } else if (e.currentTarget.scrollHeight === e.currentTarget.scrollTop + e.currentTarget.offsetHeight) {
    e.currentTarget.scrollTop -= 1;
  }
});
//prevents preventDefault from being called on document if it sees a scrollable div
$('body').on('touchmove','.scrollable',function(e) {
  e.stopPropagation();
});
