Element: lostpointercapture event
=================================

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

Syntax
------

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


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

onlostpointercapture = (event) => {};
```

Event type
----------

A `PointerEvent`. Inherits from `Event`.

Event

UIEvent

MouseEvent

PointerEventEvent 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.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.

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);
});
```
