Utilizing Angular: Leveraging the template reference within ng-content

I am looking for a way to incorporate dynamic content around an input in my Angular application.

My approach involves creating a custom component and utilizing ng-content to connect the behavior with the input. Here is an example:

<my-wrapper>
    <input type="text" otherAttributes...>
</my-wrapper>

The structure of my wrapper would look something like this:

HTML:

<span>
    <ng-content #myRef></ng-content>
    <button (click)="perform(myRef)">Click me!</button>
</span>

And the corresponding TypeScript function:

perform(myRef: HTMLIntpuElement) {
    myRef.value = 'something else';
}

I am aware that ng-content does not technically exist, and it is not possible to directly reference it since the content may consist of multiple elements. Is there a more elegant "Angular way" to access this content instead of resorting to native element manipulation?

Answer №1

Your issue can be resolved using @ContentChildren/@ContentChild in Angular. These decorators are similar to @ViewChildren/@ViewChild, with the main difference being that @ContentChild looks inside ng-content while @ViewChild does not.

 <textarea id="myId">Sample text</textarea>

In your TypeScript file:

 @ContentChild('myId') element: ElementRef;
