What is the best way to access the Component Reference in Angular 2 using the DOM element ID?

What is the Equivalent of -

angular.element(element).scope()

In Angular 2.0?

I frequently used the above code snippet to retrieve scope variable in my Angular 1.x application. Is there a comparable method in Angular 2?

If Not

If not, how can I eliminate this dependency? My code contains numerous dynamic elements, and if I were to migrate it to Angular 2, a component would need to be initialized for each element. These components could have multiple levels of child components, making it necessary to access nth level child component from the parent.

Answer №1

A recommended approach in Angular2 is to minimize DOM manipulation whenever possible. However, if it becomes necessary, you can achieve this by importing the document module using 

import { DOCUMENT } from '@angular/platform-browser';
. Then, inject it into your constructor with 
@Inject(DOCUMENT) private document
and use methods like this.document.getElementById(); for manipulation.

Alternatively, a more optimal solution can be found here: Discovering the best practices for DOM manipulation in Angular 2
