How to capture touchend coordinates?

rated 0 times [ 97] [ 3] / answers: 1 / hits: 36174 / 11 Years ago, tue, july 30, 2013, 12:00:00

I am trying to capture touch coordinate on the touchend event but get undefined. The touchstart event works good, but same concept fails on touchend. I built this code with mousedown and mouseup and that works good.

What am I missing?

div.addEvent(touchstart, function (event) {

    event.preventDefault(); // to avoid scrolling

    span.innerHTML = event.page.x;

});

div.addEvent(touchend, function (event) {

    span.innerHTML = event.page.x;

});

You need to store the values on touchmove and read it in touchend.

var lastMove = null;



// Save the touchstart to always have a position

div.addEvent('touchstart', function(event) {

  lastMove = event;

});



// Override with touchmove, which is triggered only on move

div.addEvent('touchmove', function(event) {

  lastMove = event;

});
