　　参考：http://blog.csdn.net/xh16319/article/details/9987847

　　自定义checkbox验证，“检查checkbox是否选中”

jQuery.validator.addMethod("isAgreeRule", function(value, element) {
    return element.checked;
}, "请阅读并同意用户协议后提交!");

　　添加到验证规则

$(function() {
    $("#registerFrom").validate({
        rules : {
            login_name : {
                required : true
            },
            password : {
                required : true,
                rangelength : [ 8, 20 ]
            },
            confirm_password : {
                required : true,
                equalTo : "#password"
            },
            captcha : {
                required : true
            },
            agree_rule : {
                isAgreeRule : true
            }
        },
        errorPlacement : function(error, element) {
            if (element.is(':radio') || element.is(':checkbox')) { // 如果是radio或checkbox
                var eid = element.attr('name'); // 获取元素的name属性
                error.appendTo(element.parent()); // 将错误信息添加当前元素的父结点后面
            } else {
                error.insertAfter(element);
            }
        },
        submitHandler : function(form) {
            submitFrom();
        }
    });
});

　　添加自定义样式：

<style type="text/css">
input.control-label-error {
    border: 1px solid red;
}

.control-label-error {
    padding-left: 16px;
    padding-bottom: 2px;
    font-weight: bold;
    color: #EA5200;
}
</style>

　　完整代码如下：

　　html

<%@ page language="java" pageEncoding="UTF-8"%>
<style type="text/css">
input.control-label-error {
    border: 1px solid red;
}

.control-label-error {
    padding-left: 16px;
    padding-bottom: 2px;
    font-weight: bold;
    color: #EA5200;
}
</style>
