$event object

How to get user input from the $event object?

The DOM events carry all information that is useful to the component.

The following example shows to get user input from the $event – key-up.component.ts
import { ComponentOnInit } from '@angular/core';

@Component({
  selector: 'app-key-up',
  templateUrl: './key-up.component.html',
  styleUrls: ['./key-up.component.css']
})
export class KeyUpComponent implements OnInit {

  values = '';
  constructor() { }

  ngOnInit() { }

  //KeyUp events.
  onKeyUp(eventany) {
    this.values += event.target.value + ' : ';
  }
}

And key-up.component.html –
<div class="event">
  <button (click)="onKeyUp($event)">KeyUp Event!</button>
  <p>
    {{values}}
  </p>
</div>
