如何使用redux-form处理卸载字段和字段级验证？

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

const MyForm = (props) => {
  const { handleSubmit } = props;

  const onSubmit = (values) => {
    // 处理表单提交逻辑
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <div>
        <label htmlFor="name">Name:</label>
        <Field name="name" component="input" type="text" />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <Field name="email" component="input" type="email" />
      </div>
      {/* 其他表单字段 */}
      <button type="submit">Submit</button>
    </form>
  );
};

// 使用reduxForm连接表单到Redux store
const ConnectedForm = reduxForm({
  form: 'myForm', // 表单的唯一标识
  destroyOnUnmount: false, // 防止卸载时销毁字段值
})(MyForm);

export default ConnectedForm;

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

const validate = (values) => {
  const errors = {};

  if (!values.name) {
    errors.name = 'Required';
  }

  if (!values.email) {
    errors.email = 'Required';
  }

  // 其他字段的验证规则

  return errors;
};

const MyForm = (props) => {
  const { handleSubmit } = props;

  const onSubmit = (values) => {
    // 处理表单提交逻辑
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <div>
        <label htmlFor="name">Name:</label>
        <Field name="name" component="input" type="text" />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <Field name="email" component="input" type="email" />
      </div>
      {/* 其他表单字段 */}
      <button type="submit">Submit</button>
    </form>
  );
};

// 使用reduxForm连接表单到Redux store，并传递validate函数
const ConnectedForm = reduxForm({
  form: 'myForm', // 表单的唯一标识
  destroyOnUnmount: false, // 防止卸载时销毁字段值
  validate, // 字段级验证函数
})(MyForm);

export default ConnectedForm;
