How to get host element reference?

Question

How can I get the host element reference in Angular 2?

In my case, I want to know if my component has a focus or not.

Answer 1

You get the host element reference using

class MyComponent {   constructor(private elRef:ElementRef) {     console.log(this.elRef.nativeElement);   } } 

You can also subscribe to the focus event

class MyComponent {   @HostBinding() tabindex = 0;   @HostListener('focus', ['$event'])   onFocus(event) {     console.log(event);   } } 

Answer 2

Use ViewContainerRef that represents a container where one or more views can be attached to a component.

constructor(private readonly viewRef: ViewContainerRef) {      console.log(this.viewRef.element.nativeElement); }
