不能够通过 @ngrx/component-store

Question

import { ReservationStore } from 'src/app/Store/AddReservation.store';

@Component({
  selector: 'app-new-booking-modal',
  templateUrl: './new-booking-modal.page.html',
  styleUrls: ['./new-booking-modal.page.scss'],
  providers: [ReservationStore],
})
export class NewBookingModalPage implements OnInit {
  storagetestId$ = this.reservationStore.storagetestId$;
  constructor(private reservationStore: ReservationStore) {}
  ngOnInit() {
    this.bookingFun(' changed value');
  }
  bookingFun(storagetestId) {
    this.reservationStore.patchState({ storagetestId });
  }
}

我试图通过调用商店在此处调用storagetestid的状态“ storagetestid”的价值，但要获得“ Storagetestid”的Intial值，我该如何更改状态值并在全球范围内更改状态值。我已经显示了我的商店文件和组件.ts下方 您的问题是将“提供商：[ReservationStore]”从每个组件移动到模块。

@NgModule({
  imports: [BrowserModule, FormsModule],
  declarations: [
    AppComponent,
    HelloComponent,
    NewBookingModalComponent,
    SecondViewComponent,
  ],
  bootstrap: [AppComponent],
  providers: [ReservationStore],
})
export class AppModule {}
