On ipad safari event.pageX is undefined

[Leon]

bind("touchstart",function(event){

startX = event.pageX;

}

startX is undefined

[Leon]

On ipad safari with jQuery1.6.4, it works well

[Leon]

e.flyDiv.bind("touchstart",function(event){

startX = event.pageX; startY = event.pageY;

});

attributes as clientX, offsetX are also undefined

[Leon]

I tried a test on click function, as follow:

e.flyDiv.bind("click",function(event){

startX = event.pageX; startY = event.pageY;

});

It just works!

Touch Events don't have those properties; they're hidden behind an array of touches. Please ask for help on the forums or StackOverflow.

Thanks, Scott. But when I used version 1.6.4, touch events just had x/y properties, and all things go well. My project just crashed when I updated jQuery to v1.8.3(so I had to roll back to the old version). Can you check if x/y properties is hidden by jQuery?

Sounds like you need to use event.originalEvent.pageX, since jQuery doesn't know anything about touch events it doesn't try to normalize them.

Well, thanks for your help!
