import { Component, ElementRef, HostListener, Input } from '@angular/core';

@Component({
  selector: 'selector',
  template: `
    <div style="width: 200px; height: 200px; display: inline-block" [style.backgroundColor]="makeDifferent">
      {{text}}
    </div>
  `
})
export class AnotherComponent {
  public text: String;

  @Input() makeDifferent;

  @HostListener('document:click', ['$event'])
  clickout(event) {
    if(this.eRef.nativeElement.contains(event.target)) {
      this.text = "clicked inside";
    } else {
      this.text = "clicked outside";
    }
  }

  constructor(private eRef: ElementRef) { }
}
