Element: webkitmouseforcechanged event

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

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.

Syntax

addEventListener("webkitmouseforcechanged", (event) => { })

onwebkitmouseforcechanged = (event) => { }

Event type

A MouseEvent. Inherits from UIEvent and Event.

MouseEvent.metaKey Read only: Returns true if the meta key was down when the mouse event was fired.
MouseEvent.movementX Read only: The X coordinate of the mouse pointer relative to the position of the last mousemove event.
MouseEvent.movementY Read only: The Y coordinate of the mouse pointer relative to the position of the last mousemove event.
MouseEvent.offsetX Read only: The X coordinate of the mouse pointer relative to the position of the padding edge of the target node.
