var idCard = new IdCard();
var msg = idCard.Fill("430102190001010883").Check(true);//true 开启检查
console.log(msg);//一下是msg的信息
用于解析15和18位身份证，成功返回
{

Error
null

birthday
"1900-01-01"

city
"长沙市"

county
"芙蓉区"

gender
"女"

idCard
"430102190001010883"

province
"湖南省"

}

如果Error不为null 则为获取失败数据格式如下
{

Error
Object { errMsg="获取区域代码失败"}

errMsg
"获取区域代码失败"

birthday
undefined

city
undefined

county
undefined

gender
undefined

idCard
"430102190001010883"

province
undefined

}

目录结构说明：

areaCode.json　　　　数据源
areaCodeNew.json　　采集来的新数据，数据来源于http://www.shurufa8.cn/shenfenzheng.html
IdCardIndex.htm　　用于解析areaCodeNew.json的页面
my.js　　　　　　　　用于解析areaCodeNew.json的js，配合IdCardIndex.htm使用，定期获取新数据更新areaCodeNew.json重新解析后替换areaCode.json的数据
index.js　　　　　　　解析身份证的js
