将帮助文本传递给redux-form

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

// 自定义的包含帮助文本的表单字段组件
const CustomInput = ({ input, meta, label, helpText }) => (
  <div>
    <label>{label}</label>
    <input {...input} />
    {meta.touched && meta.error && <span>{meta.error}</span>}
    <span>{helpText}</span>
  </div>
);

// 表单验证规则
const validate = values => {
  const errors = {};
  // 添加表单字段的验证逻辑
  return errors;
};

// 表单组件
const MyForm = props => {
  const { handleSubmit } = props;
  return (
    <form onSubmit={handleSubmit}>
      <Field
        name="myField"
        component={CustomInput}
        label="My Field"
        helpText="This is the help text for My Field."
      />
      <button type="submit">Submit</button>
    </form>
  );
};

// 使用reduxForm高阶函数包装表单组件
const MyFormContainer = reduxForm({
  form: 'myForm',
  validate,
})(MyForm);

export default MyFormContainer;
