import React, { Component } from 'react';
import { IonSelect, IonSelectOption, IonLabel } from '@ionic/react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      selectedValue: 'default' // 设置默认值
    };
  }

  handleSelectChange = (event) => {
    this.setState({ selectedValue: event.target.value });
  }

  render() {
    return (
      <IonSelect value={this.state.selectedValue} onIonChange={this.handleSelectChange}>
        <IonSelectOption value="option1">Option 1</IonSelectOption>
        <IonSelectOption value="option2">Option 2</IonSelectOption>
        <IonSelectOption value="option3">Option 3</IonSelectOption>
      </IonSelect>
    );
  }
}

export default MyComponent;
