Lingi lülitumise probleem Angularis

Lahendame lingi lülitumise probleemi marsruutimises. Selle probleemi saab lahendada teeki RxJS abil, mis on juba Angularisse kaasatud.

Alustuseks impordime klassi Subscription:

app/aaaa/aaaa.component.tsimport { Subscription } from 'rxjs';

Loome privaatse omaduse:

app/aaaa/aaaa.component.tsexport class AaaaComponent { 
  private subscription: Subscription;
}

Loome omaduse parameetri id salvestamiseks:

app/aaaa/aaaa.component.tsexport class AaaaComponent { 
  id: number | undefined;
  private subscription: Subscription;
}

Ja nüüd tellime parameetri id muutuse marsruudist:

app/aaaa/aaaa.component.tsexport class AaaaComponent { 
  id: number | undefined;
  private subscription: Subscription;
  
  constructor(private activateRoute: ActivatedRoute) {
    this.subscription = activateRoute.params.subscribe(params => this.id = params['id']);
  }
}
