有没有谁有15位身份证验证的方法?
18位的可以根据最后一位的校验码的正误来判断,但15位的没有校验码,不知道有没办法来解决?

------解决方案--------------------
身份证校验最好写在前台程序中。如下面js代码
==================================================================
功能：验证身份证号码是否有效
提示信息：未输入或输入身份证号不正确！
使用：isIDno(obj,string)
返回：bool
==================================================================

var show = IfShow(ShowMsg);
