正则表达式如何验证身份证号？

Answer 1

Function IDCheck(e)
IDCheck = true
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
'IDCheck= "身份证号共有 15 码或18位"
IDCheck = False
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
'IDCheck= "身份证除最后一位外，必须为数字！"
IDCheck = False
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
'IDCheck= "身份证输入错误！"
IDCheck = False
Exit Function
End If
If strMonth > 12 Or strDay > 31 Then
IDCheck = False
'IDCheck= "身份证输入错误！"
Exit Function
End If
Else
'IDCheck= "身份证输入错误！"
IDCheck = False
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
IDCheck = Ai
If Len(e) = 18 And e 〈〉 Ai Then
'IDCheck= "身份证号码输入错误！"
IDCheck = False
Exit Function
End If
End Function

var myRegExp=/^\d{17}[\d|x]$|^\d{15}$/i;用myRegExp就可以验证输入的字符串是否符合身份证的编码规则了或者你直接把/^\d{17}[\d|x]$|^\d{15}$/i;放入控件的正则表达式属性里面就OK了
