i'm trying to implement a touch listener for tablets to trigger some actions depending whether it touchmoved upwards or downwards.
I tried the native listener:
($document).bind('touchmove', function (e)
{
alert("it worked but i don't know the direction");
});
But i don't know how to determine the direction.
Is this possible?
Or do i need to use touchstart/touchend, if I need this can I determine the direction before the touch movement stops?
If I can only do this with an external library, what's the best one?
thanks.
I had some issues in Ipad and solved it with two events
var ts;
$(document).bind('touchstart', function (e){
ts = e.originalEvent.touches[0].clientY;
});
$(document).bind('touchend', function (e){
var te = e.originalEvent.changedTouches[0].clientY;
if(ts > te+5){
slide_down();
}else if(ts < te-5){
slide_up();
}
});
