Ionic 3-如何将对象数组与valueChanges Observable合并

import { Component } from '@angular/core';
import { FormBuilder, FormControl, FormGroup } from '@angular/forms';
import { combineLatest } from 'rxjs';

@Component({
  selector: 'app-my-form',
  template: `
    <form [formGroup]="myForm">
      <div formArrayName="items">
        <div *ngFor="let item of myForm.controls.items.controls; let i = index">
          <input type="text" [formControlName]="i">
        </div>
      </div>
    </form>
  `,
})
export class MyFormComponent {
  myForm: FormGroup;

  constructor(private formBuilder: FormBuilder) {
    this.myForm = this.formBuilder.group({
      items: this.formBuilder.array([
        new FormControl('Item 1'),
        new FormControl('Item 2'),
        new FormControl('Item 3')
      ])
    });

    const itemsArray = this.myForm.get('items').valueChanges;
    const combined = combineLatest([itemsArray]);

    combined.subscribe(([items]) => {
      console.log(items);
      // 这里可以做一些逻辑处理或者调用其他相关方法
    });
  }
}
