只读 Window property event 返回 事件 which is currently being handled by the site's code. Outside the context of an event handler, the value is always undefined .

should avoid using this property in new code, and should instead use the 事件 passed into the event handler function. This property is not universally supported and even when supported introduces potential fragility to your code.

注意: This property can be fragile, in that there may be situations in which the returned 事件 is not the expected value. In addition, Window.event is not accurate for events dispatched within shadow trees .
