在Angular中动态创建控件时不呈现formControlName

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

// 创建一个FormControl对象
const dynamicControl = new FormControl();

// 创建一个FormGroup对象
const dynamicGroup = new FormGroup({
  dynamicControl: new FormControl()
});

<input [formControl]="dynamicControl" type="text">

<form [formGroup]="dynamicGroup">
  <input formControlName="dynamicControl" type="text">
</form>
