刚才在网上看到一个居民身份证验证asp函数,感觉到在做用户注册的时候可以用到,于是就转过来,以便大家到时候用到,方便使用。并且经过我的测试,完全没有问题,测试结果是:
1、输入错误的身份证号,程序会输出相应的错误提示。
2、输入正确的身份证号,程序会将这个身份证号直接输出。
函数具体代码如下:
<% Function CheckCardId(e) arrVerifyCode = Split("1,0,x,9,8,7,6,5,4,3,2", ",") Wi = Split("7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2", ",") Checker = Split("1,9,8,7,6,5,4,3,2,1,1", ",") If Len(e) < 15 Or Len(e) = 16 Or Len(e) = 17 Or Len(e) > 18 Then CheckCardId= "身份证号共有 15 码或18位" Exit Function End If Dim Ai If Len(e) = 18 Then Ai = Mid(e, 1, 17) ElseIf Len(e) = 15 Then Ai = e Ai = Left(Ai, 6) & "19" & Mid(Ai, 7, 9) End If If Not IsNumeric(Ai) Then CheckCardId= "身份证除最后一位外,必须为数字!" Exit Function End If Dim strYear, strMonth, strDay strYear = CInt(Mid(Ai, 7, 4)) strMonth = CInt(Mid(Ai, 11, 2)) strDay = CInt(Mid(Ai, 13, 2)) BirthDay = Trim(strYear) + "-" + Trim(strMonth) + "-" + Trim(strDay) If IsDate(BirthDay) Then If DateDiff("yyyy",Now,BirthDay) <-140 or cdate(BirthDay)> date() Then CheckCardId= "身份证输入错误!" Exit Function End If If strMonth > 12 Or strDay > 31 Then CheckCardId= "身份证输入错误!" Exit Function End If Else CheckCardId= "身份证输入错误!" Exit Function End If Dim i, TotalmulAiWi For i = 0 To 16 TotalmulAiWi = TotalmulAiWi + CInt(Mid(Ai, i + 1, 1)) * Wi(i) Next Dim modValue modValue = TotalmulAiWi Mod 11 Dim strVerifyCode strVerifyCode = arrVerifyCode(modValue) Ai = Ai & strVerifyCode CheckCardId = Ai If Len(e) = 18 And e <> Ai Then CheckCardId= "身份证号码输入错误!" Exit Function End If End Function response.write CheckCardId("528337194801020025") %>(鼠标移到代码上去,在代码的顶部会出现四个图标,第一个是查看源代码,第二个是复制代码,第三个是打印代码,第四个是帮助)
