Actions of Event Binding

Actions of Event Binding - Angular 4

In an event binding, Angular sets up an event handler for the target event.

Example looks like -
import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'on-click',
  template: `<div>
        <div><button (click)="onClick($event)"> keyup here.</button> <p>{{message}}</p></div>
        <div><input (keyup)="onKey($event)"> <p>{{values}}</p></div>  </div>`
})
export class clickComponent {
  values = '';

  onClick(event) {
    console.log(event);
  }

  onKey(event: any) {
    //without type info
    this.values += event.target.value + ' | ';
  }
}

Example 2 – dblclick keypress
import { ComponentOnInit } from '@angular/core';

@Component({
  selector: 'on-click',
  template: '<div> <button (keypress)="OnKeypress()"> keypress here.</button>{{message}} </div>'
})
export class KeypressComponent {
  message = "";

  OnKeypress() {
    this.message = 'Hey, How are You?';
  }
}
