How to find event type in Typescript

Question

Here is my template

<input (keyup)="onKey($event)">

Here is my typescript file

onKey(event:any) {
  console.log(typeof event);
}

console.logdeduces object, but actually it should be KeyboardEvent.

Is there a general way to search for an event type?

Answer 1

You probably want to just check event.typeto find out what it is and infer the type from it.

Otherwise, you can try using event instanceof KeyboardEventeither custom types of protection .

Also, in your example, you can just make an argument event:KeyboardEventinstead event:any.
