import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable({
  providedIn: 'root'

export class DataService {
  private dataSource = new BehaviorSubject(Object);
  public currentData = this.dataSource.asObservable();

  constructor() {}

  changeData(data) {
    this.dataSource.next(data);
  }
}

new :红色部分是重点

import { Injectable } from '@angular/core';
import { BehaviorSubject, Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class DataService {
  private dataSource = new BehaviorSubject(Object);
  public currentData: Observable<Object> = this.dataSource.asObservable();

  constructor() {}

  changeData(data) {
    this.dataSource.next(data);
  }
}
