Returns the Element
(EventTarget
) on which the touch contact started when it was first placed on the surface, even if the touch point has since moved outside the interactive area of that element or even been removed from the document. Note that if the target element is removed from the document, events will still be targeted at it, and hence won't necessarily bubble up to the window or document anymore. If there is any risk of an element being removed while it is being touched, the best practice is to attach the touch listeners directly to the target.
var el = touchPoint.target;
el
Touch
object.This example illustrates how to access the Touch
object's Touch.target
property. The Touch.target
property is an Element
(EventTarget
) on which a touch point is started when contact is first placed on the surface.
In following simple code snippet, we assume the user initiates one or more touch contacts on the source
element. When the touchstart
event handler for this element is invoked, each touch point's Touch.target
property is accessed via the event's TouchEvent.targetTouches
list.
// Register a touchmove listener for the 'source' element var src = document.getElementById("source"); src.addEventListener('touchstart', function(e) { // Iterate through the touch points that were activiated // for this element. for (var i=0; i < e.targetTouches.length; i++) { console.log("touchpoint[" + i + "].target = " + e.targetTouches[i].target); } }, 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.
