如何在angular 7中将()表单重置为特定值

<form #myForm="ngForm">
  <!-- 表单元素 -->
</form>

import { Component, ViewChild } from '@angular/core';
import { NgForm } from '@angular/forms';

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

  resetForm() {
    this.myForm.resetForm({
      // 设置表单元素的特定值
      fieldName: '特定值',
      // 其他表单元素的特定值
    });
  }
}

<button (click)="resetForm()">重置表单</button>
