Angular 6-如何提交表单的一个区域(而不是整个表单)

<form [formGroup]="myForm">
  <div>
    <label for="name">姓名：</label>
    <input type="text" id="name" formControlName="name">
  </div>
  
  <div>
    <label for="email">邮箱：</label>
    <input type="email" id="email" formControlName="email">
  </div>
  
  <button (click)="submitPartialForm()">提交</button>
</form>

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

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponentComponent implements OnInit {
  myForm: FormGroup;
  
  constructor(private formBuilder: FormBuilder) { }
  
  ngOnInit() {
    this.myForm = this.formBuilder.group({
      name: [''],
      email: ['']
    });
  }
  
  submitPartialForm() {
    // 处理提交表单的逻辑
    // 可以通过this.myForm.value获取表单中各个控件的值
    // 可以根据需要选择性提交某个区域的数据
  }
}
