# Element: webkitmouseforcewillbegin event

{{APIRef("Force Touch Events")}}{{Non-standard_header}}

Safari for macOS fires the non-standard **`webkitmouseforcewillbegin`** event at an {{domxref("Element")}} before firing the initial {{domxref("Element/mousedown_event", "mousedown")}} event.

This offers the opportunity to tell the system not to trigger any default Force Touch actions if and when the click turns into a [Force Touch events](/en-US/docs/Web/API/Force_Touch_events).

To instruct macOS not to engage any default Force Touch actions if the user apply enough pressure to activate a Force Touch event, call {{domxref("Event.preventDefault", "preventDefault()")}} on the `webkitmouseforcewillbegin` event object.

**`webkitmouseforcewillbegin`** is a proprietary, WebKit-specific event. It is part of the [Force Touch events](/en-US/docs/Web/API/Force_Touch_events) feature.

## Syntax

Use the event name in {{domxref("EventTarget/addEventListener", "addEventListener()")}}:

```js-nolint
addEventListener("webkitmouseforcewillbegin", (event) => { })
```

Alternatively, assign to the [event handler property](/en-US/docs/Web/API/Document_Object_Model/Events#using_onevent_properties) of the interface:

```js-nolint
onwebkitmouseforcewillbegin = (event) => { }
```

## Event type

A {{domxref("MouseEvent")}}. Inherits from {{domxref("UIEvent")}} and {{domxref("Event")}}.
