Element: webkitmouseforcedown event

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

After a {{domxref("Element.mousedown_event", "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.

Syntax

Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}}, or set an event handler property.

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

onwebkitmouseforcedown = (event) => { }

Event type

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

Event properties

This interface also inherits properties of its parents, {{domxref("UIEvent")}} and {{domxref("Event")}}.

• {{domxref("MouseEvent.altKey")}} {{ReadOnlyInline}}
  • : Returns true if the <kbd>alt</kbd> key was down when the mouse event was fired.
• {{domxref("MouseEvent.button")}} {{ReadOnlyInline}}
  • : The button number that was pressed (if applicable) when the mouse event was fired.
• {{domxref("MouseEvent.buttons")}} {{ReadOnlyInline}}
  • : The buttons being pressed (if any) when the mouse event was fired.
• {{domxref("MouseEvent.clientX")}} {{ReadOnlyInline}}
  • : The X coordinate of the mouse pointer in viewport coordinates.
• {{domxref("MouseEvent.clientY")}} {{ReadOnlyInline}}
  • : The Y coordinate of the mouse pointer in viewport coordinates.
• {{domxref("MouseEvent.ctrlKey")}} {{ReadOnlyInline}}
  • : Returns true if the <kbd>control</kbd> key was down when the mouse event was fired.
• {{domxref("MouseEvent.layerX")}} {{Non-standard_inline}} {{ReadOnlyInline}}
  • : Returns the horizontal coordinate of the event relative to the current layer.
• {{domxref("MouseEvent.layerY")}} {{Non-standard_inline}} {{ReadOnlyInline}}
  • : Returns the vertical coordinate of the event relative to the current layer.
• {{domxref("MouseEvent.metaKey")}} {{ReadOnlyInline}}
  • : Returns true if the <kbd>meta</kbd> key was down when the mouse event was fired.
• {{domxref("MouseEvent.movementX")}} {{ReadOnlyInline}}
  • : The X coordinate of the mouse pointer relative to the position of the last {{domxref("Element/mousemove_event", "mousemove")}} event.
• {{domxref("MouseEvent.movementY")}} {{ReadOnlyInline}}
  • : The Y coordinate of the mouse pointer relative to the position of the last {{domxref("Element/mousemove_event", "mousemove")}} event.
• {{domxref("MouseEvent.offsetX")}} {{ReadOnlyInline}}
  • : The X coordinate of the mouse pointer relative to the position of the padding edge of the target node.
• {{domxref("MouseEvent.offsetY")}} {{ReadOnlyInline}}
  • : The Y coordinate of the mouse pointer relative to the position of the padding edge of the target node.
• {{domxref("MouseEvent.pageX")}} {{ReadOnlyInline}}
  • : The X coordinate of the mouse pointer relative to the whole document.
• {{domxref("MouseEvent.pageY")}} {{ReadOnlyInline}}
  • : The Y coordinate of the mouse pointer relative to the whole document.
• {{domxref("MouseEvent.relatedTarget")}} {{ReadOnlyInline}}
  • : The secondary target for the event, if there is one.
• {{domxref("MouseEvent.screenX")}} {{ReadOnlyInline}}
  • : The X coordinate of the mouse pointer in screen coordinates.
• {{domxref("MouseEvent.screenY")}} {{ReadOnlyInline}}
  • : The Y coordinate of the mouse pointer in screen coordinates.
• {{domxref("MouseEvent.shiftKey")}} {{ReadOnlyInline}}
  • : Returns true if the <kbd>shift</kbd> key was down when the mouse event was fired.
• {{domxref("MouseEvent.mozInputSource")}} {{non-standard_inline()}} {{ReadOnlyInline}}
  • : The type of device that generated the event (one of the MOZ_SOURCE_* constants). This lets you, for example, determine whether a mouse event was generated by an actual mouse or by a touch event (which might affect the degree of accuracy with which you interpret the coordinates associated with the event).
• {{domxref("MouseEvent.webkitForce")}} {{non-standard_inline()}} {{ReadOnlyInline}}
  • : The amount of pressure applied when clicking.
• {{domxref("MouseEvent.x")}} {{ReadOnlyInline}}
  • : Alias for {{domxref("MouseEvent.clientX")}}.
• {{domxref("MouseEvent.y")}} {{ReadOnlyInline}}
  • : Alias for {{domxref("MouseEvent.clientY")}}.
