如何使用Angular 8+从控制器中选中离子框架中的选择框选项？

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

@Component({
  selector: 'app-example',
  templateUrl: 'example.component.html',
  styleUrls: ['example.component.css']
})
export class ExampleComponent {
  form: FormGroup;

  constructor(private formBuilder: FormBuilder) {
    this.form = this.formBuilder.group({
      option: '' // 初始化选择框的值为空
    });
  }
}

<form [formGroup]="form">
  <ion-item>
    <ion-label>选择框</ion-label>
    <ion-select formControlName="option">
      <ion-select-option value="option1">选项1</ion-select-option>
      <ion-select-option value="option2">选项2</ion-select-option>
      <ion-select-option value="option3">选项3</ion-select-option>
    </ion-select>
  </ion-item>
</form>

const selectedOption = this.form.get('option').value;
console.log(selectedOption);
