布线更改时组件之间的BehaviorSubject

// service.ts
import { BehaviorSubject } from 'rxjs';

export class WiringService {
  private wiringStatusSubject: BehaviorSubject<boolean> = new BehaviorSubject<boolean>(false);

  public getWiringStatus(): Observable<boolean> {
    return this.wiringStatusSubject.asObservable();
  }

  public updateWiringStatus(status: boolean): void {
    this.wiringStatusSubject.next(status);
  }
}

// component1.ts
import { WiringService } from './service';

export class Component1 {
  constructor(private wiringService: WiringService) {}

  public updateWiring(): void {
    // 更新布线
    this.wiringService.updateWiringStatus(true);
  }
}

// component2.ts
import { WiringService } from './service';

export class Component2 {
  public wiringStatus: boolean;

  constructor(private wiringService: WiringService) {
    this.wiringService.getWiringStatus().subscribe((status: boolean) => {
      this.wiringStatus = status;
      // 布线状态发生变化，执行相应操作
    });
  }
}
