如何获取react redux-form下拉菜单的selected value onChange

npm install react-redux-form

import React from 'react';
import { Field, reduxForm } from 'redux-form';

class MyForm extends React.Component {
  render() {
    return (
      <form>
        {/* 其他表单字段 */}
        <Field name="myDropdown" component={renderDropdown} onChange={this.handleDropdownChange} />
      </form>
    );
  }

  handleDropdownChange = (event, newValue, previousValue) => {
    // 在这里处理下拉菜单的选定值变化
    console.log(newValue);
  }
}

// 渲染下拉菜单的组件
const renderDropdown = ({ input, meta }) => (
  <select {...input}>
    <option value="option1">Option 1</option>
    <option value="option2">Option 2</option>
    <option value="option3">Option 3</option>
  </select>
);

// 使用reduxForm对组件进行包装
MyForm = reduxForm({
  form: 'myForm'
})(MyForm);

export default MyForm;
