Question

Is there a way to access the element reference of a component directly within the template?

When I mouse over certain elements, I use the following code to set focus:

<div #divTemplateVar (mouseover)="divTemplateVar.focus()"></div>

However, this method does not work for components:

<component #componentTemplateVar (mouseover)="componentTemplateVar.focus()"></component>

I am aware that I can use

viewChild('componentTemplateVar', { read: ElementRef })

to select the component in the template. But I have multiple components that need to automatically focus themselves on mouseover, and I do not want to manually write a view child for each one.

Is there a way to make component children auto-focus themselves on the mouseover event?

Here is a suggested implementation for creating a directive that focuses on an element when hovered over:

export class HoverFocusDirective {

  constructor(
    private el: ElementRef<HTMLElement>
  ) { }

  @HostListener('mouseover')
  onMouseOver() {
    this.el.nativeElement.focus();
  }

  @HostListener('mouseout')
  onMouseOut() {
    this.el.nativeElement.blur();
  }

}
