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); } }
