使用来自angular 10中的另一个组件的数据更新对象

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

@Injectable({
  providedIn: 'root'
})
export class SharedService {
  private sharedData: any;

  constructor() { }

  setData(data: any) {
    this.sharedData = data;
  }

  getData() {
    return this.sharedData;
  }
}

import { Component } from '@angular/core';
import { SharedService } from 'path-to-shared-service';

@Component({
  selector: 'app-provider-component',
  template: `
    <button (click)="updateData()">Update Data</button>
  `
})
export class ProviderComponent {
  constructor(private sharedService: SharedService) { }

  updateData() {
    const newData = { /* 新的数据对象 */ };
    this.sharedService.setData(newData);
  }
}

import { Component } from '@angular/core';
import { SharedService } from 'path-to-shared-service';

@Component({
  selector: 'app-consumer-component',
  template: `
    <div>{{ sharedData }}</div>
  `
})
export class ConsumerComponent {
  sharedData: any;

  constructor(private sharedService: SharedService) { }

  ngOnInit() {
    this.sharedData = this.sharedService.getData();
  }
}
