使用Window对象调用函数时正确获取angular服务对象引用

import { Component, OnInit, Inject } from '@angular/core';
import { WINDOW } from '@ng-toolkit/universal';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponentComponent implements OnInit {
  constructor(@Inject(WINDOW) private window: Window) { }

  ngOnInit() {
    // 在这里可以使用this.window对象调用函数
    this.window.myFunction();
  }
}

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

@Injectable({
  providedIn: 'root'
})
export class MyService {
  myFunction() {
    // 这里是函数的具体实现
    console.log('调用了myFunction');
  }
}

import { Component, OnInit } from '@angular/core';
import { MyService } from '../my.service';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponentComponent implements OnInit {
  constructor(private myService: MyService) { }

  ngOnInit() {
    // 在这里可以使用this.myService对象调用myFunction函数
    this.myService.myFunction();
  }
}
