入门案例：
<html> <head> <meta charset="UTF-8"> <title>validate入门案例</title> <script type="text/javascript" src="js/jquery-1.8.3.js"></script> <!--validate.js是建立在jquery之上的，所以得先导入jquery的类库--> <script type="text/javascript" src="js/jquery.validate.min.js"></script> <!--引入国际化js文件--> <script type="text/javascript" src="js/messages_zh.js"></script> <script> $(function() { $("#checkForm").validate({ rules: { username: { required: true, minlength: 6 }, password: { required: true, digits: true, minlength: 6 } }, messages: { username: { required: "用户名不能为空!", minlength: "用户名不得少于6位！" }, password: { required: "密码不能为空!", digits: "密码必须是数字!", minlength: "密码不得少于6位!" } } }); }); </script> </head> <body> <form action="#" id="checkForm"> 用户名：<input type="text" name="username" /><br /> 密码：<input type="password" name="password" /><br /> <input type="submit" /> </form> </body> </html>
注意：这里需要导入三个js文件
效果：
