Angular 8-如何在添加动态表单组时防止响应式表单验证？

import { FormBuilder, FormGroup, Validators } from '@angular/forms';

constructor(private formBuilder: FormBuilder) {
  this.myForm = this.formBuilder.group({
    // 添加表单控件和验证规则
    // ...
  });
}

<form [formGroup]="myForm">
  <!-- 添加表单控件 -->
  <!-- ... -->
</form>

import { FormArray } from '@angular/forms';

// 在表单组中创建一个名为dynamicFormArray的FormArray
this.myForm.addControl('dynamicFormArray', new FormArray([]));

<div formArrayName="dynamicFormArray">
  <div *ngFor="let control of myForm.get('dynamicFormArray').controls; let i = index">
    <!-- 添加动态表单组的表单控件 -->
    <!-- ... -->
  </div>
</div>

import { FormControl, Validators } from '@angular/forms';

// 创建一个新的表单组
const newFormGroup = new FormGroup({
  // 添加表单控件和验证规则
  // ...
});

// 将新的表单组添加到动态表单组中
(this.myForm.get('dynamicFormArray') as FormArray).push(newFormGroup);
