</head>
<body>
<div class="container">

    <div class="form-group">
      <label for="inputEmail">Email address</label>
      <input type="email" class="form-control" id="inputEmail" placeholder="Enter email">
    </div>
    <div class="form-group">
      <label for="inputPassword">Password</label>
      <input type="password" class="form-control" id="inputPassword" placeholder="Password">
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </form>
</div>
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js"></script>

2. jQuery Validation Plugin

jQuery Validation Plugin 是一个轻量级的表单验证插件，它可以与 jQuery 一起使用，为表单提供客户端验证功能。该插件支持多种验证规则，如电子邮件、数字、URL、日期等。

代码示例：

$(document).ready(function(){

    rules: {
      email: {
        required: true,
        email: true
      },
      password: {
        required: true,
        minlength: 5
      },
      confirm_password: {
        required: true,
        minlength: 5,
        equalTo: "#password"
      }
    },
    messages: {
      email: {
        required: "Please enter your email address",
        email: "Please enter a valid email address"
      },
      password: {
        required: "Please provide a password",
        minlength: "Your password must be at least 5 characters long"
      },
      confirm_password: {
        required: "Please provide a password",
        minlength: "Your password must be at least 5 characters long",
        equalTo: "Please enter the same password as above"
      }
    }
  });
});

3. React Formik

React Formik 是一个用于构建复杂表单的 React 库。它提供了一系列的实用工具和组件，使得在 React 应用中处理表单变得更加简单。Formik 内置了验证和提交逻辑，减少了代码量。

代码示例：

import React from 'react';
import { Formik, Field, Form } from 'formik';
import * as Yup from 'yup';

const SignupForm = () => {
  const validationSchema = Yup.object().shape({
    email: Yup.string()
      .email('Email is invalid')
      .required('Email is required'),
    password: Yup.string()
      .min(8, 'Password must be at least 8 characters')
      .required('Password is required'),
  });

  return (
    <Formik
      initialValues={{ email: '', password: '' }}
      validationSchema={validationSchema}
      onSubmit={(values, { setSubmitting }) => {
        setTimeout(() => {
          alert(JSON.stringify(values, null, 2));
          setSubmitting(false);
        }, 400);
      }}
    >
      {({ isSubmitting }) => (
        <Form>
          <Field type="email" name="email" />
          <Field type="password" name="password" />
          <button type="submit" disabled={isSubmitting}>
            Submit
          </button>
        </Form>
      )}
    </Formik>
  );
};

export default SignupForm;

4. Vue.js VeeValidate

VeeValidate 是一个用于 Vue.js 的表单验证库。它支持多种验证规则，并与 Vue.js 的响应式系统无缝集成。VeeValidate 提供了简单的 API 和丰富的文档，使得在 Vue.js 应用中进行表单验证变得非常容易。

代码示例：

<template>
  <div>
    <form @submit.prevent="submitForm">
      <div>
        <label for="email">Email:</label>
        <Field type="email" id="email" name="email" v-model="email" />
        <ErrorMessage name="email" class="text-danger" />
      </div>
      <div>
        <label for="password">Password:</label>
        <Field type="password" id="password" name="password" v-model="password" />
        <ErrorMessage name="password" class="text-danger" />
      </div>
      <button type="submit">Submit</button>
    </form>
  </div>
</template>

<script>
import { required, email } from 'vee-validate/dist/rules';
import { extend, ValidationObserver, ValidationProvider, ErrorMessage } from 'vee-validate';

extend('required', {
  ...required,
  message: 'This field is required',
});

extend('email', {
  ...email,
  message: 'Please enter a valid email',
});

export default {
  components: {
    ValidationObserver,
    ValidationProvider,
    ErrorMessage,
  },
  data() {
    return {
      email: '',
      password: '',
    };
  },
  methods: {
    submitForm() {
      this.$refs.observer.validate().then((success) => {
        if (success) {
          alert('Form submitted!');
        }
      });
    },
  },
