Angular中的多个<input>字段

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

@Component({
  selector: 'app-form',
  template: `
    <form [formGroup]="myForm" (ngSubmit)="onSubmit()">
      <input type="text" formControlName="field1">
      <input type="text" formControlName="field2">
      <button type="submit">Submit</button>
    </form>
  `,
})
export class FormComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      field1: new FormControl(),
      field2: new FormControl(),
    });
  }

  onSubmit() {
    console.log(this.myForm.value);
  }
}
