参数及说明：
------------------- 配置参数:----------------------
-------- 表单 --------
valid(fileds,isBindSubmit,isAlert)
参数一为表单项数组（Json方式），必需
参数二为表单是否为手动调用验证结果，默认为true，即为自动验证submit事件，可选；
参数三为验证信息采用Alert提示方式，默认为否，可选。
-------- 表单项数组 --------
name: 表单域的name，必需
type: 验证类型，可选
simple: 简单提示消息，只输入域的中文名 [推荐]
message: 完整的提示消息，替代简单提示消息
require:是否必填，默认为true，即必填，false为非必填，可选
to: 匹配值对比，对象的name，可选
value: 直接匹配值对比，有to则该值被忽略，可选
min:最小长度，可选
max:最大长度，可选
ajax: 为取得异步验证的结果的地址，可选
****** type验证类型如下： ******
eng: 英文
chn: 汉字
mail: 邮箱
url: 网址
currency: 货币
number: 数字
int: 整数
double: 浮点数
username:数字和英文及下划线和.的组合，开头为字母，4-20个字符
password: 数字和英文及下划线的组合，6-20个字符
safe:不含特殊字符
dbc: 含全角字符(汉字除外)
qq: 5-9位数字
date: 时间
year: 年
month:月
day: 日
hour: 小时
minute:分
second 秒

**** 以下类型，需要有匹配对象或值 ****
eq: =
gt: >
gte:>=
lt: <
lte:<=
----------------------------------------------------
怎么个简单容易法？？？
看代码：
$(function(){
$("form").valid([
//验证选择
{ name:"checkbox",simple:"多选" },
//验证必填,只要不为空
{ name:"username",simple:"用户名" },
//非必填，邮箱类型
{ name:"email",type:"mail",simple:"邮箱",require:false }
]);
})
