I had a problem figuring out how to get the X / Y coordinates where the finger touches the web application on iPhone Safari.
I have a function subscribed to the events "touchstart", "touchmove" and "touchhend", and I tried pageX / pageY on this event, but it seems to get nothing but 'undefined' or 0.
I also think that my keyword search is not quite right, because I did not find clear documentation on how to do this anywhere.
