    <ion-select formControlName="selectedData" multiple="true">
      <ion-select-option value="data1">数据1</ion-select-option>
      <ion-select-option value="data2">数据2</ion-select-option>
      <ion-select-option value="data3">数据3</ion-select-option>

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

@Component({
  selector: 'app-my-component',
  templateUrl: 'my-component.html',
})
export class MyComponent {
  myForm: FormGroup;

  constructor(private formBuilder: FormBuilder) {
    this.myForm = this.formBuilder.group({
      selectedData: [[]], // 初始化为空数组
    });
  }
}

submitForm() {
  const selectedData = this.myForm.value.selectedData;
  console.log(selectedData); // 输出选择的数据数组
  // 进行其他操作，如发送到服务器等
}
