javascript scroll event for iPhone/iPad ?

Question

I can't seem to capture the scroll event on an iPad. None of these work, what I am doing wrong?

window.onscroll=myFunction;

document.onscroll=myFunction;

window.attachEvent("scroll",myFunction,false);

document.attachEvent("scroll",myFunction,false);

They all work even on Safari 3 on Windows. Ironically, EVERY browser on the PC supports window.onload= if you don't mind clobbering existing events. But no go on iPad.

Answer 1

The iPhoneOS does capture onscroll events, except 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 6-1.

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

The usual way of installing the handler works e.g.

window.onscroll = function() { alert("Scrolled"); };
