PointerEvent.pressure

The normalized pressure of the pointer input in the range of 0 to 1, where 0 and 1 represent the minimum and maximum pressure the hardware is capable of detecting, respectively. For hardware that does not support pressure, including but not limited to mouse, the value MUST be 0.5 when the pointer is active and 0 otherwise.

This property is Read only .

Syntax

var pressure = pointerEvent.pressure;

Return value

pressure
The amount of pressure applied to the pointer.

Example

This example illustrates using the pressure property.

When a pointerdown event is fired, different functions are called depending on the value of the event's pressure property.

someElement.addEventListener('pointerdown', function(ev) {
   if (ev.pressure == 0) {
     // No pressure
     process_no_pressure(ev);
   } else if (ev.pressure == 1) {
     // Maximum pressure
     process_max_pressure(ev);
   } else {
     // Default
     process_pressure(ev);
   }
 }, false);
