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 properties
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
to1
, where0
and1
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
to1
, where0
is the neutral position of the control. PointerEvent.tiltX
Read only-
The plane angle (in degrees, in the range of
-90
to90
) 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
to90
) 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
to359
. 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);
});
