The lostpointercapture event is fired when a captured pointer is released.

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

addEventListener("lostpointercapture", (event) => {});

onlostpointercapture = (event) => {};

A PointerEvent. Inherits from Event.

This interface inherits properties from MouseEvent and Event.

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.

This example listens for the lostpointercapture event for an element, and captures the pointer for the element on pointerdown. When the user subsequently releases the pointer, the lostpointercapture event will be fired.

const para = document.querySelector("p");

para.addEventListener("lostpointercapture", () => {
  console.log("I've been released!");
});

para.addEventListener("pointerdown", (event) => {
  para.setPointerCapture(event.pointerId);
});

The same example, but using the onlostpointercapture event handler property:

const para = document.querySelector("p");

para.onlostpointercapture = () => {
  console.log("I've been released!");
};

para.addEventListener("pointerdown", (event) => {
  para.setPointerCapture(event.pointerId);
});
