Example

This example illustrates the TouchEvent object's TouchEvent.touches property. The TouchEvent.touches property is a TouchList object and containing a list of Touch objects for every point of contact currently touching the surface.

In following code snippet, the touchstart event handler checks the length of the TouchEvent.touches list to determine the number of touch points that were activated and then invokes different handlers depending on the number of touch points.

someElement.addEventListener('touchstart', function(e) {
   // Invoke the appropriate handler depending on the 
   // number of touch points.
   switch (e.touches.length) {
     case 1: handle_one_touch(e); break;
     case 2: handle_two_touches(e); break;
     case 3: handle_three_touches(e); break;
     default: console.log("Not supported"); break;
   }   
 }, false);
