What is the best way to obtain a reference to an instance of my Angular 2 directive?

Angular 2 rc 5 was written using typescript 1.9

I am trying to access the instance of my attribute directive. Although I am using ViewChild, which typically works with components, it is giving me a handle to the element containing the directive.

template

<span myHighlight #directive> Highlight me! </span>

component

/** Trying to get a handle to the directive but receiving the span element instead */
@ViewChild('directive') directive:HighlightDirective;

ngAfterViewInit(){
   console.log(this.directive);
}

directive

@Directive({ selector: '[myHighlight]' })
export class HighlightDirective {
    constructor(el: ElementRef, renderer: Renderer) {
       renderer.setElementStyle(el.nativeElement, 'backgroundColor', 'yellow');
    }
}

Check out the live example here

The <span> element is being displayed in the console, indicating that ViewChild is not returning what I expected. How can I obtain a reference to the actual directive instance?

Answer №1

@ViewChildren('directive', {read: HighlightDirective}) directive:HighlightDirective;

alternatively

@ViewChildren(HighlightDirective) directive:HighlightDirective;

however, this second method will retrieve the first instance of HighlightDirective, not a specific one.
