Holding an element in TypeScript Angular2 proved to be challenging due to an error encountered during the process

I attempted to access a div element in my HTML using ElementRef, document, and $('#ID') but unfortunately, it did not work. I tried implementing this in ngOnInit, ngAfterViewInit, and even in my constructor.

Another method I tried was using @ViewChild.

The issue I am facing is that when I call $('#ID'), it returns undefined until there has been some interaction with the template.

All I need is to simply access a div tag from my HTML page.

(I am currently using Angular 2 rc1 and would appreciate any help in identifying the source of the problem) Thank you!

Answer №1

In a nutshell: The "Angular way" advises against direct DOM access, as it can be slow and make code maintenance difficult.

The method for accessing the div depends on your specific need. For updating text within the div, you can utilize interpolation with {{ }}:

<div> {{ text_value_from_model }} </div>

If you want to handle a click event on the div:

<div (click)="onClick()">Text</div>
