Validate验证插件，内置丰富的验证规则，还有灵活的自定义规则接口，HTML、CSS与JS之间的低耦合能让您自由布局和丰富样式，支持input,select,textarea的验证。

Description

浏览器支持：IE7+ 、Chrome、Firefox、Safari、Mobile Browser

jQuery版本：1.7.0+

Usage
载入jQuery、validate

DOM标签验证规则填写

<div class="form_control">
 <input class="required" value="315359131@qq.com" type="text" name="email" data-tip="请输入您的邮箱" data-valid="isNonEmpty||isEmail" data-error="email不能为空||邮箱格式不正确">
</div>
<div class="form_control">
 <select class="required" data-valid="isNonEmpty" data-error="省份必填">
  <option value="">请选择省份</option>
  <option value="001">001</option>
  <option value="002">002</option>
 </select>
</div>

给需要验证的表单元素的class填入required（不建议在这个class上做其他样式）。
建议input用独立div包裹，因为验证的message是从当前input的父元素上append生成。
data-tip：在尚未验证而获取焦点时出现的提示。
data-valid：验证规则，若有组合验证，以||符号分割。
data-error：验证错误提示，对应data-valid，以||符号分割。
单选/复选比较特殊，需要添加元素包裹单选/复选集合，并在包裹元素上加验证规则。

<div class="form_control">
 <span class="required" data-valid="isChecked" data-error="性别必选" data-type="radio">
   <label><input type="radio" name="sex">男</label>
   <label><input type="radio" name="sex">女</label>
   <label><input type="radio" name="sex">未知</label>
 </span>
</div>
<div class="form_control">
 <span class="required" data-valid="isChecked" data-error="标签至少选择一项" data-type="checkbox">
   <label><input type="checkbox" name="label">红</label>
   <label><input type="checkbox" name="label">绿</label>
   <label><input type="checkbox" name="label">蓝</label>
 </span>
</div>

JS调用

//**注意：必须以表单元素调用validate**
 $('form').validate({
  type:{
   isChecked: function(value, errorMsg, el) {
    var i = 0;
    var $collection = $(el).find('input:checked');
    if (!$collection.length) {
     return errorMsg;
    }
   }
  },
  onFocus: function() {
   this.parent().addClass('active');
   return false;
  },
  onBlur: function() {
   var $parent = this.parent();
   var _status = parseInt(this.attr('data-status'));
   $parent.removeClass('active');
   if (!_status) {
    $parent.addClass('error');
   }
   return false;
  }
 });

表单提交前的验证

 $('form').on('submit', function(event) {
  event.preventDefault();
  $(this).validate('submitValidate'); //return true or false;
 });

validate内置验证规则

required:true 必输字段
remote:"check.php" 使用ajax方法调用check.php验证输入值
email:true 必须输入正确格式的电子邮件
url:true 必须输入正确格式的网址
date:true 必须输入正确格式的日期
dateISO:true 必须输入正确格式的日期(ISO)，例如：2009-06-23，1998/01/22 只验证格式，不验证有效性
number:true 必须输入合法的数字(负数，小数)
digits:true 必须输入整数
creditcard: 必须输入合法的信用卡号
equalTo:"#field" 输入值必须和#field相同
accept: 输入拥有合法后缀名的字符串（上传文件的后缀）
maxlength:5 输入长度最多是5的字符串(汉字算一个字符)
minlength:10 输入长度最小是10的字符串(汉字算一个字符)
rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符)
range:[5,10] 输入值必须介于 5 和 10 之间
max:5 输入值不能大于5
min:10 输入值不能小于10

例子：
验证用户名，密码，确认密码，主页，生日，邮箱等
首先引入Jquery、引入jquery.validate.js、引入messages_cn.js并且为表单定义一个id，为需要验证的控件定义name属性，并赋值，此插件使用的是控件的name属性，而非id。

Python vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AM

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AM

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.
