如何在ReactJS中使用validator.js？

npm install validator

yarn add validator

import validator from 'validator';

import React, { useState } from 'react';

const MyForm = () => {
  const [email, setEmail] = useState('');
  const [emailError, setEmailError] = useState('');

  const handleInputChange = (e) => {
    setEmail(e.target.value);
  };

  const handleSubmit = (e) => {
    e.preventDefault();

    if (validator.isEmail(email)) {
      // 邮箱地址有效，执行提交逻辑
      setEmailError('');
      // 执行提交逻辑...
    } else {
      // 邮箱地址无效，显示错误信息
      setEmailError('请输入有效的邮箱地址');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" value={email} onChange={handleInputChange} />
      {emailError && <div>{emailError}</div>}
      <button type="submit">提交</button>
    </form>
  );
};

export default MyForm;
