Properties

Readonly allTouches

allTouches: readonly TouchData[]

All the current touches.

Readonly altKey

altKey: boolean

True if the alt key was down when the mouse event was fired.

Readonly clientX

clientX: number

The X coordinate of the mouse pointer in local (DOM content) coordinates.

Readonly clientY

clientY: number

The Y coordinate of the mouse pointer in local (DOM content) coordinates.

Readonly ctrlKey

ctrlKey: boolean

True if the control key was down when the mouse event was fired.

Readonly currentTarget

currentTarget: null | EventTarget

A reference to the currently registered target for the event. This is the object to which the event is currently slated to be sent. It's possible this has been changed along the way through retargeting.

Readonly force

force: number

The amount of pressure being applied to the surface by the user, as a float between 0.0 (no pressure) and 1.0 (maximum pressure).

Readonly identifier

identifier: number

A unique identifier for the implied touch object.

Readonly metaKey

metaKey: boolean

True if the meta key was down when the mouse event was fired.

Readonly pageX

pageX: number

The X coordinate of the touch point relative to the left edge of the document. Unlike clientX, this value includes the horizontal scroll offset, if any.

Readonly pageY

pageY: number

The Y coordinate of the touch point relative to the top of the document. Unlike clientY, this value includes the vertical scroll offset, if any.

Readonly radiusX

radiusX: number

The X radius of the ellipse that most closely circumscribes the area of contact with the screen. The value is in pixels of the same scale as screenX.

Readonly radiusY

radiusY: number

The Y radius of the ellipse that most closely circumscribes the area of contact with the screen. The value is in pixels of the same scale as screenY.

Readonly rotationAngle

rotationAngle: number

The angle (in degrees) that the ellipse described by radiusX and radiusY must be rotated, clockwise, to most accurately cover the area of contact between the user and the surface.

Readonly screenX

screenX: number

The X coordinate of the mouse pointer in global (screen) coordinates.

Readonly screenY

screenY: number

The Y coordinate of the mouse pointer in global (screen) coordinates.

Readonly shiftKey

shiftKey: boolean

True if the shift key was down when the mouse event was fired.

Readonly target

target: null | EventTarget

A reference to the target to which the event was originally dispatched.

Readonly timeStamp

timeStamp: number

The time at which the event was created (in milliseconds). By specification, this value is time since epoch—but in reality, browsers' definitions vary. In addition, work is underway to change this to be a DOMHighResTimeStamp instead.
