event property

Event? get event

The read-only Window property event returns the Event which is currently being handled by the site's code. Outside the context of an event handler, the value is always undefined.

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

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

Implementation

external Event? get event;
