javascript - How to capture touchend coordinates?

Question

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;
});
