firesTouchEvents - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The InputDeviceCapabilities.firesTouchEvents read-only property returns a Boolean 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.
