是 DOMString representing the name of the event (see PointerEvent event types ).

PointerEventInit 可选

• pointerId — optional and defaulting to 0 , of type long , that sets the value of the instance's PointerEvent.pointerId .
• width — optional and defaulting to 1 , of type double , that sets the value of the instance's PointerEvent.width .
• height — optional and defaulting to 1 , of type double , that sets the value of the instance's PointerEvent.height .
• pressure — optional and defaulting to 0 , of type float , that sets the value of the instance's PointerEvent.pressure .
• tangentialPressure — optional and defaulting to 0 , of type float , that sets the value of the instance's PointerEvent.tangentialPressure .
• tiltX — optional and defaulting to 0 , of type long , that sets the value of the instance's PointerEvent.tiltX .
• tiltY — optional and defaulting to 0 , of type long , that sets the value of the instance's PointerEvent.tiltY .
• twist — optional and defaulting to 0 , of type long , that sets the value of the instance's PointerEvent.twist .
• pointerType — optional and defaulting to "" , of type DOMString , that sets the value of the instance's PointerEvent.pointerType .
• isPrimary — optional and defaulting to false , of type 布尔 , that sets the value of the instance's PointerEvent.isPrimary .
