Element: pointerdown event
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.
The pointerdown event is fired when a pointer becomes active. For mouse, it is fired when the device transitions from no buttons pressed to at least one button pressed. For touch, it is fired when physical contact is made with the digitizer. For pen, it is fired when the stylus makes physical contact with the digitizer.
This behavior is different from mousedown events. When using a physical mouse, mousedown events fire whenever any button on a mouse is pressed down. pointerdown events fire only upon the first button press; subsequent button presses don't fire pointerdown events.
Note:
For touchscreen browsers that allow direct manipulation, a pointerdown event triggers implicit pointer capture, which causes the target to capture all subsequent pointer events as if they were occurring over the capturing target. Accordingly, pointerover, pointerenter, pointerleave, and pointerout will not fire as long as this capture is set. The capture can be released manually by calling element.releasePointerCapture on the target element, or it will be implicitly released after a pointerup or pointercancel event.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
addEventListener("pointerdown", (event) => { })
onpointerdown = (event) => { }
Event type
A PointerEvent. Inherits from Event.
Event properties
This interface inherits properties from MouseEvent and Event.
PointerEvent.altitudeAngleRead only Experimental-
Represents the angle between a transducer (a pointer or stylus) axis and the X-Y plane of a device screen.
PointerEvent.azimuthAngleRead 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.persistentDeviceIdRead only Experimental-
A unique identifier for the pointing device generating the
PointerEvent. PointerEvent.pointerIdRead only-
A unique identifier for the pointer causing the event.
PointerEvent.widthRead only-
The width (magnitude on the X axis), in CSS pixels, of the contact geometry of the pointer.
PointerEvent.heightRead only-
The height (magnitude on the Y axis), in CSS pixels, of the contact geometry of the pointer.
PointerEvent.pressureRead only-
The normalized pressure of the pointer input in the range
0to1, where0and1represent the minimum and maximum pressure the hardware is capable of detecting, respectively. PointerEvent.tangentialPressureRead only-
The normalized tangential pressure of the pointer input (also known as barrel pressure or cylinder stress) in the range
-1to1, where0is the neutral position of the control. PointerEvent.tiltXRead only-
The plane angle (in degrees, in the range of
-90to90) between the Y–Z plane and the plane containing both the pointer (e.g., pen stylus) axis and the Y axis. PointerEvent.tiltYRead only-
The plane angle (in degrees, in the range of
-90to90) between the X–Z plane and the plane containing both the pointer (e.g., pen stylus) axis and the X axis. PointerEvent.twistRead only-
The clockwise rotation of the pointer (e.g., pen stylus) around its major axis in degrees, with a value in the range
0to359. PointerEvent.pointerTypeRead only-
Indicates the device type that caused the event (mouse, pen, touch, etc.).
PointerEvent.isPrimaryRead only-
Indicates if the pointer represents the primary pointer of this pointer type.
Examples
Using addEventListener():
const para = document.querySelector("p");
para.addEventListener("pointerdown", (event) => {
console.log("Pointer down event");
});
Using the onpointerdown event handler property:
const para = document.querySelector("p");
para.onpointerdown = (event) => {
console.log("Pointer down event");
};
