Angular-da havolalarni almashtirish muammosi
Keling, routingda havolalarni almashtirish muammosining yechimini ko'rib chiqaylik. Bu muammoni Angularga allaqachon kiritilgan RxJS kutubxonasi yordamida hal qilish mumkin.
Boshlanish uchun Subscription klassini import qilamiz:
import { Subscription } from 'rxjs';
Xususiy xususiyat yaratamiz:
export class AaaaComponent {
private subscription: Subscription;
}
id nomli parametrni saqlash uchun xususiyat yaratamiz:
export class AaaaComponent {
id: number | undefined;
private subscription: Subscription;
}
Endi routingdan id parametrining o'zgarishiga obuna bo'lamiz:
export class AaaaComponent {
id: number | undefined;
private subscription: Subscription;
constructor(private activateRoute: ActivatedRoute) {
this.subscription = activateRoute.params.subscribe(params => this.id = params['id']);
}
}
