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);
