如何在Angular中从表单中获取数据

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

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

  constructor() {
    this.myForm = new FormGroup({
      firstName: new FormControl(),
      lastName: new FormControl()
    });
  }
}

<form [formGroup]="myForm" (ngSubmit)="onSubmit()">
  <label for="firstName">First Name:</label>
  <input type="text" id="firstName" formControlName="firstName">

  <label for="lastName">Last Name:</label>
  <input type="text" id="lastName" formControlName="lastName">

  <button type="submit">Submit</button>
</form>

onSubmit() {
  const firstName = this.myForm.get('firstName').value;
  const lastName = this.myForm.get('lastName').value;

  // 在这里可以对获取到的数据进行进一步处理
}
