下面代码进行对jQuery Validation的简单演示包含必填项、字符长度，格式验证

一、引入文件

<script src="js/jquery-1.8.0.min.js" type="text/javascript"></script>
<script src="js/jquery.validate.js" type="text/javascript"></script>

二、声明HTML片段

<form action="" id="jvForm">
	  用 户 名:<input type="text" name="username"/></br>
	  密    码:<input type="password" name="password" id="password"/></br>
	  确认密码:<input type="password" name="confirm_password"/></br>
	  出 生 地:<select name="address"><option value="">--</option><option value="1">北京</option>
	<option value="1">上海</option><option value="1">深圳</option></select></br>
	  手    机:<input type="text" name="mobile" /></br>
	  邮    箱:<input type="text" name="email" /></br>
	  <input type="submit" value="提交" />
</form>

三、错误提示样式

<style type="text/css">
	label.error{font-size:12px;font-weight: normal;color:#ff0511;margin-left:10px;}
</style>

四、验证代码

<script type = "text/javascript">
$(function() {
    $("#jvForm").validate({
        rules: {
            username: { //用户名必填 至少3位 
                required: true,
                minlength: 3
            },
            password: { //密码必填 至少6位 
                required: true,
                minlength: 6
            },
            confirm_password: { //密码确认 
                required: true,
                equalTo: "#password"
            },
            address: { //出生地必填  
                required: true
            },
            mobile: { //手机必填  验证格式 
                required: true,
                mobile: true
            },
            email: { //email必填 验证格式  
                required: true,
                email: true
            },

        },
        messages: {
            username: {
                required: "用户名不能为空!",
                minlength: "用户名至少三位!"
            },
            password: {
                required: "密码不能为空!",
                minlength: "密码至少六位!"
            },
            confirm_password: {
                required: "密码确认不能为空!",
                equalTo: "两次输入密码不一致 !"
            },
            address: {
                required: "请选择出生地!",
            },
            mobile: {
                required: "手机不能为空!",
                mobile: "手机格式不对",
            },
            email: {
                required: "邮箱不能为空!",
                email: "邮箱格式不对",
            },
        }
    });
}) 
</script>

由于jquery.validate.js中没有mobile验证。所以须要自己添加一个

首先找到messages 在里面加入mobile 例如以下：

messages: {
	required: "This field is required.",
	remote: "Please fix this field.",
	email: "Please enter a valid email address.",
	url: "Please enter a valid URL.",
	date: "Please enter a valid date.",
	dateISO: "Please enter a valid date (ISO).",
	number: "Please enter a valid number.",
	mobile: "请填写正确的手机号码.",
	digits: "Please enter only digits.",
	creditcard: "Please enter a valid credit card number.",
	equalTo: "Please enter the same value again.",
	maxlength: $.validator.format("Please enter no more than {0} characters."),
	minlength: $.validator.format("Please enter at least {0} characters."),
	rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."),
	range: $.validator.format("Please enter a value between {0} and {1}."),
	max: $.validator.format("Please enter a value less than or equal to {0}."),
	min: $.validator.format("Please enter a value greater than or equal to {0}.")
}

然后在methods中加入 mobile的正则校验

mobile: function( value, element ) {
	return this.optional(element) || /^1[3|4|5|8][0-9]\d{8}$/.test(value);
}

执行效果
