PointerEvent.pressure

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 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 and 0 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);
