  • For the touchstart event, it is a list of the touch points that became active with the current event.
  • For the touchmove event, it is a list of the touch points that have changed since the last event.
  • For the touchend event, it is a list of the touch points that have been removed from the surface (that is, the set of touch points corresponding to fingers no longer touching the surface).

This property is Read only .

Syntax

var changes = touchEvent.changedTouches;

Return value

changes
A TouchList whose Touch objects include all the touch points that contributed to this touch event.

Example

This example illustrates the TouchEvent object's TouchEvent.changedTouches property. The TouchEvent.changedTouches property is a TouchList object that contains one Touch object for each touch point which contributed to the event.

In following code snippet, the touchmove event handler iterrates through the changedTouches list and prints the identifier of each touch point that changed since the last event.

someElement.addEventListener('touchmove', function(e) {
   // Iterate through the list of touch points that changed
   // since the last event and print each touch point's identifier.
   for (var i=0; i < e.changedTouches.length; i++) {
     console.log("changedTouches[" + i + "].identifier = " + e.changedTouches[i].identifier);
   }   
}, false);
