InputDeviceCapabilities: firesTouchEvents property

The firesTouchEvents read-only property of the InputDeviceCapabilities interface returns a boolean value that indicates whether the device dispatches touch events.

You can use this property to detect mouse events that represent an action that may already have been handled by touch event handlers. This doesn't necessarily mean the device is a touch screen. For example, stylus and mouse devices typically generate touch events on mobile browsers.

Value

Example

});
