The tangentialPressure
read-only property of the PointerEvent
interface represents the normalized tangential pressure of the pointer input (also known as barrel pressure or cylinder stress) in the range -1 to 1, where 0 is the neutral position of the control.
Note that some hardware may only support positive values in the range 0 to 1. For hardware that does not support tangential pressure, the value will be 0.
Syntax
var tanPressure = pointerEvent.tangentialPressure;
Value
A float representing the amount of tangential pressure applied to the pointer.
Example
When a pointerdown
event is fired, different functions are called depending on the value of the event's tangentialPressure
property.
someElement.addEventListener('pointerdown', function(ev) { if (ev.tangentialPressure == 0) { // No pressure process_no_tanPressure(ev); } else if (ev.tangentialPressure == 1) { // Maximum pressure process_max_tanPressure(ev); } else { // Default process_tanPressure(ev); } }, false);

1. From version 54: this feature is behind the dom.w3c_pointer_events.enabled
preference (needs to be set to true
). To change preferences in Firefox, visit about:config.
