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.
After a mousedown
event has been fired at the element, if and when sufficient pressure has been applied to the mouse or trackpad button to qualify as a "force click," Safari begins sending webkitmouseforcedown
events to the element.
webkitmouseforcedown
is a proprietary, WebKit-specific event. It is part of the Force Touch events feature.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("webkitmouseforcedown", (event) => {});
onwebkitmouseforcedown = (event) => {};
This interface also inherits properties of its parents, UIEvent
and Event
.
