Hi List,
I'm oberserving some weired behaviour when using the Mobile Safari
touch events. I'm giving an example:
I've registered a "touchstart" event handler for the document:
document.addEventListener('touchstart', touch_handler, true);
In my handler, I'm analyzing the touches list of the event. When only
one finger is involved, I can find the touch event in
event.touches[0] // --> first finger
But when 2 fingers are used sometimes (but sometimes not) the position
of the touch events in the touches array switch, meaning sometimes
it's
event.touches[0] // --> first finger
event.touches[1] // --> second finger
which is what I would consider correct behaviour, but sometimes the
touches array looks like
event.touches[0] // --> second finger
event.touches[1] // --> first finger
I've got no idea what causes the switch. I don't even know if this
behaviour is considered to be correct (my personal opinion is that the
indexes should be consistent for the life time of the event) and I
should deal with it or if it is a bug.
Did anybody make similar experiences?
Thanks,
Towbie
