The pressure
read-only property of the PointerEvent
interface indicates the normalized pressure of the pointer input.
The pressure
read-only property of the PointerEvent
interface indicates the normalized pressure of the pointer input.
The normalized pressure of the pointer input in the range of 0
to 1
, inclusive, where 0
and 1
represent the minimum and maximum pressure the hardware is capable of detecting, respectively. For hardware that does not support pressure, such as a mouse, the value is 0.5
when the pointer is active buttons state and 0
otherwise.
In this snippet, when a pointerdown
event is fired, different functions are called depending on the value of the event's pressure
property.
js
someElement.addEventListener( "pointerdown", (event) => { if (event.pressure === 0) { // No pressure process_no_pressure(event); } else if (event.pressure === 1) { // Maximum pressure process_max_pressure(event); } else { // Default process_pressure(event); } }, false, );
