Ipad Scrolling

The iPad does capture onscroll events, but not the way you may expect.

One-finger panning doesn’t generate any events until the user stops panning—an onscroll event is generated when the page stops moving and redraws—as shown in Figure 1.

Similarly, scroll with 2 fingers fires onscroll only after you've stopped scrolling.

Conclusion: When scrolling tesxt on an ipad, use two fingers.
