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：
接下来就是表单验证：
这里是用js实现的：http://www.cnblogs.com/xuyiqing/p/8372726.html
现在用jQuery实现：
效果：
代码：

errorElement: "label", //用来创建错误提示信息标签,validate插件默认的就是label
success: function(label) { //验证成功后的执行的回调函数
//label指向上面那个错误提示信息标签label
label.text(" ") //清空错误提示消息
.addClass("success"); //加上自定义的success类
}
});
