如果'this‘，RXJS Angular 2可观察到丢失航迹

import { Observable } from 'rxjs';

export class MyComponent {
  myObservable: Observable<any>;

  constructor() {
    this.myObservable = new Observable(observer => {
      // 在这里使用箭头函数确保'this'的正确性
      setInterval(() => {
        observer.next('数据更新');
      }, 1000);
    });
  }

  ngOnInit() {
    this.myObservable.subscribe(data => {
      console.log(data);
    });
  }
}

import { Observable } from 'rxjs';

export class MyComponent {
  myObservable: Observable<any>;

  constructor() {
    this.myObservable = new Observable(observer => {
      setInterval(function() {
        observer.next('数据更新');
      }.bind(this), 1000);
    });
  }

  ngOnInit() {
    this.myObservable.subscribe(data => {
      console.log(data);
