从Angular 11观察值中获取简单的字符串数组

import { of } from 'rxjs';

// 创建一个 Observable 发出字符串数组
const stringArray$ = of(['apple', 'banana', 'orange']);

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
  stringArray: string[];

  ngOnInit() {
    // 订阅 Observable 并获取字符串数组
    stringArray$.subscribe(array => {
      this.stringArray = array;
      console.log(this.stringArray);  // 在控制台打印字符串数组
    });
  }
}

<div *ngFor="let item of stringArray">{{ item }}</div>
