How to detect a long touch pressure with javascript for android and iphone? native javascript or jquery...
I want something that sound like :
<input type='button' onLongTouch='myFunc();' />
The problem with using Touch End to detect the long touch is it won't work if you want the event to fire after a certain period of time. It is better to use a timer on touch start and clear the event timer on touch end. The following pattern can be used:
var onlongtouch;
var timer;
var touchduration = 500; //length of time we want the user to touch before we do something
touchstart() {
timer = setTimeout(onlongtouch, touchduration);
}
touchend() {
//stops short touches from firing the event
if (timer)
clearTimeout(timer); // clearTimeout, not cleartimeout..
}
onlongtouch = function() { //do something };
