Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The non-standard webkitmouseforcechanged
event is fired by Safari each time the amount of pressure changes on the trackpad/touchscreen.
webkitmouseforcechanged
is a proprietary, WebKit-specific event introduced by Apple to support their Force Touch events feature.
This event first fires after the mousedown
event and stops firing before the mouseup
event.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("webkitmouseforcechanged", (event) => {});
onwebkitmouseforcechanged = (event) => {};
This interface also inherits properties of its parents, UIEvent
and Event
