{{APIRef("Pointer Events")}}

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

Syntax

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

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

onlostpointercapture = (event) => { }

Event type

A {{domxref("PointerEvent")}}. Inherits from {{domxref("Event")}}.

Event properties

This interface inherits properties from {{domxref("MouseEvent")}} and {{domxref("Event")}}.

  • {{domxref('PointerEvent.altitudeAngle')}} {{ReadOnlyInline}} {{experimental_inline}}
    • : Represents the angle between a transducer (a pointer or stylus) axis and the X-Y plane of a device screen.
  • {{domxref('PointerEvent.azimuthAngle')}} {{ReadOnlyInline}} {{experimental_inline}}
    • : Represents the angle between the Y-Z plane and the plane containing both the transducer (a pointer or stylus) axis and the Y axis.
  • {{domxref('PointerEvent.persistentDeviceId')}} {{ReadOnlyInline}} {{experimental_inline}}
    • : A unique identifier for the pointing device generating the PointerEvent.
  • {{domxref('PointerEvent.pointerId')}} {{ReadOnlyInline}}
    • : A unique identifier for the pointer causing the event.
  • {{domxref('PointerEvent.width')}} {{ReadOnlyInline}}
    • : The width (magnitude on the X axis), in CSS pixels, of the contact geometry of the pointer.
  • {{domxref('PointerEvent.height')}} {{ReadOnlyInline}}
    • : The height (magnitude on the Y axis), in CSS pixels, of the contact geometry of the pointer.
  • {{domxref('PointerEvent.pressure')}} {{ReadOnlyInline}}
    • : 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.
  • {{domxref('PointerEvent.tangentialPressure')}} {{ReadOnlyInline}}
    • : 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.
  • {{domxref('PointerEvent.tiltX')}} {{ReadOnlyInline}}
    • : 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.
  • {{domxref('PointerEvent.tiltY')}} {{ReadOnlyInline}}
    • : 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.
  • {{domxref('PointerEvent.twist')}} {{ReadOnlyInline}}
    • : 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.
  • {{domxref('PointerEvent.pointerType')}} {{ReadOnlyInline}}
    • : Indicates the device type that caused the event (mouse, pen, touch, etc.).
  • {{domxref('PointerEvent.isPrimary')}} {{ReadOnlyInline}}
    • : Indicates if the pointer represents the primary pointer of this pointer type.

Examples

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.

js
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:

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

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

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