TouchList
listing all the Touch
objects for touch points that are still in contact with the touch surface, regardless of whether or not they've changed or what their target element was at touchstart
time.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);

[1] Touch events were implemented in Gecko 18.0, but removed again in 24.0 (Firefox 24.0 / Thunderbird 24.0 / SeaMonkey 2.21) on the desktop version of Firefox due to web compatibility issues (bug 888304).
[2] As of Gecko 52.0, touch events support has been fixed and reenabled in Windows desktop platforms.
