Element: pointerrawupdate event

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The pointerrawupdate event is fired when a pointer changes any properties that don't fire pointerdown or pointerup events. See pointermove for a list of these properties.

The pointerrawupdate event may have coalesced events if there is already another pointerrawupdate event with the same pointer ID that hasn't been dispatched in the event loop. For information on coalesced events, see the PointerEvent.getCoalescedEvents() documentation.

pointerrawupdate is intended for applications that require high-precision input handling and cannot achieve smooth interaction using coalesced pointermove events alone. However, because listening to pointerrawupdate events can affect performance, you should add these listeners only if your JavaScript needs high-frequency events and can handle them as quickly as they are dispatched. For most use cases, other pointer event types should suffice.

This event bubbles and is composed, but is not cancelable and has no default action.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("pointerrawupdate", (event) => { })
onpointerrawupdate = (event) => { }

Event type

A PointerEvent. Inherits from Event.

Event properties

This interface inherits properties from MouseEvent and Event.

PointerEvent.altitudeAngle Read only Experimental: Represents the angle between a transducer (a pointer or stylus) axis and the X-Y plane of a device screen.
PointerEvent.azimuthAngle Read only Experimental: Represents the angle between the Y-Z plane and the plane containing both the transducer (a pointer or stylus) axis and the Y axis.
PointerEvent.persistentDeviceId Read only Experimental: A unique identifier for the pointing device generating the PointerEvent.
PointerEvent.pointerId Read only: A unique identifier for the pointer causing the event.
PointerEvent.width Read only: The width (magnitude on the X axis), in CSS pixels, of the contact geometry of the pointer.
PointerEvent.height Read only: The height (magnitude on the Y axis), in CSS pixels, of the contact geometry of the pointer.
PointerEvent.pressure Read only: The normalized pressure of the pointer input in the range 0 to 1, where 0 and 1 represent the minimum and maximum pressure the hardware is capable of detecting, respectively.
PointerEvent.tangentialPressure Read only: The normalized tangential pressure of the pointer input (also known as barrel pressure or cylinder stress) in the range -1 to 1, where 0 is the neutral position of the control.
PointerEvent.tiltX Read only: The plane angle (in degrees, in the range of -90 to 90) between the Y–Z plane and the plane containing both the pointer (e.g., pen stylus) axis and the Y axis.
PointerEvent.tiltY Read only: The plane angle (in degrees, in the range of -90 to 90) between the X–Z plane and the plane containing both the pointer (e.g., pen stylus) axis and the X axis.
PointerEvent.twist Read only: The clockwise rotation of the pointer (e.g., pen stylus) around its major axis in degrees, with a value in the range 0 to 359.
PointerEvent.pointerType Read only: Indicates the device type that caused the event (mouse, pen, touch, etc.).
PointerEvent.isPrimary Read only: Indicates if the pointer represents the primary pointer of this pointer type.

Example

addEventListener("pointerrawupdate", (event) => {
 if (event.getCoalescedEvents && event.getCoalescedEvents().length > 1) {
 console.log("Coalesced events:", event.getCoalescedEvents().length);
 for (let coalescedEvent of event.getCoalescedEvents()) {
 // Do something with the coalesced events.
 }
 } else {
 // Do something with the event.
 console.log("Raw event", event);
 }
});
