jquery validate自定义checkbox验证规则和样式

　　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>
