redux-forms字段级验证函数将触发与其关联的每个字段，而不仅仅是更改的字段

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';
  } else if (!/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i.test(values.email)) {
    errors.email = 'Invalid email address';
  }

  return errors;
};

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

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label>Name</label>
        <div>
          <Field name="name" component="input" type="text" />
        </div>
      </div>
      <div>
        <label>Email</label>
        <div>
          <Field name="email" component="input" type="email" />
        </div>
      </div>
      <button type="submit">Submit</button>
    </form>
  );
};

export default reduxForm({
  form: 'myForm',
  validate,
})(MyForm);
