Angular :带有ngFor的FormGroup表单。如何收集数据？

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

@Component({
  selector: 'app-registration',
  templateUrl: './registration.component.html',
  styleUrls: ['./registration.component.css']
})
export class RegistrationComponent {
  registrationForm: FormGroup;

  constructor() {
    this.registrationForm = new FormGroup({
      name: new FormControl(''),
      email: new FormControl(''),
      password: new FormControl('')
    });
  }
}

<form [formGroup]="registrationForm" (ngSubmit)="onSubmit()">
  <div>
    <label for="name">Name:</label>
    <input type="text" id="name" formControlName="name">
  </div>
  <div>
    <label for="email">Email:</label>
    <input type="email" id="email" formControlName="email">
  </div>
  <div>
    <label for="password">Password:</label>
    <input type="password" id="password" formControlName="password">
  </div>
  <button type="submit">Submit</button>
</form>

onSubmit() {
  // 获取表单数据
  const formData = this.registrationForm.value;
  console.log(formData);
  // 可以在这里进行数据处理、验证等操作
}
