The pressure
read-only property of the PointerEvent
interface indicates the normalized pressure of the pointer input.
Syntax
var pressure = pointerEvent.pressure;
Return value
pressure
- The normalized pressure of the pointer input in the range of
0
to1
, inclusive, where0
and1
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 is0.5
when the pointer is active buttons state and0
otherwise.
Example
In this snippet, when a pointerdown
event is fired, different functions are called depending on the value of the event's pressure
property.
someElement.addEventListener('pointerdown', function(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);
