How can I get children elements from QueryList in Angular 2?

Question

I am newbie at Angular2. In my view I have few identical children that are generated in *ngFor.

Answer 1

If clients is set from an async call (for example to the server) then the elements don't exist in ngAfterViewInit() yet.

You can use

ngAfterViewInit() {
  this.processingItems.changes.subscribe(() => {
    this.processingItems.toArray().forEach(el => {
        console.log(el);
    });
  });
}
