几个比较好用的asp检查函数

因为比较简单，我就不说什么了。一看就明白的！

Function ChkStr(InString)

If InString<>"" Then

InString=Replace(LCase(InString)," ","")

InString=Replace(LCase(InString),";","")

InString=Replace(LCase(InString),"'","")

InString=Replace(LCase(Instring),"--","")

Instring=Replace(LCase(Instring),"%","")

InString=Replace(LCase(InString),"%20","")

InString=Replace(LCase(InString),"admin","")

InString=Replace(LCase(InString),"and","")

InString=Replace(LCase(InString),"or","")

InString=Replace(LCase(InString),"asc","")

InString=Replace(LCase(Instring),"chr","")

InString=Replace(LCase(InString),"mid","")

InString=Replace(LCase(InString),"len","")

InString=Replace(LCase(InString),"select","")

InString=Replace(LCase(InString),"insert","")

InString=Replace(LCase(InString),"delete","")

InString=Replace(LCase(InString),"update","")

ChkStr=InString

End If

End Function

Function CheckFileExt(FileExt)

Dim FileAccessExt,AccessExt

AccessExt="gif,jpg,jpeg,bmp,doc,txt,png"

FileAccessExt=Split(AccessExt,",")

For i=LBound(FileAccessExt) to UBound(FileAccessExt)

If LCase(FileExt)=LCase(FileAccessExt(i)) Then

CheckFileExt=True

Else

CheckFileExt=False

End If

End Function

Function CheckStr(str,IsStr)

CheckStr=str

If IsStr And InStr(str,",")>0 Then

Call errmsg("提交字符中包含非法字符")

ElseIf (Not IsStr) And (Not IsNumeric(str)) Then

Call errmsg("提交不是数字型")

End If

End Function

Sub errmsg(str)

If Not IsNull(str) Then

Response.Write(str)&"&lt br &gt"

Call ASCpy()

Response.End() 'Very Improtan.Stop execute program.

End If

End Sub

Sub ASCpy()

Response.Write "<link href='Css/Maincss.css' rel='stylesheet' type='text/css'>"

Response.Write "<div align='center' class='Maincss'>"

Response.Write("<Center>Error happed!<br>Please Contract ")

Response.Write("Name:<a href='mailto:jdqn@sjzu.edu.cn' style='text-decoration:none'>")

Response.Write("<font Color=red>AloneSword</font>")

Response.Write("</a>.<br>Thank you!!!</Center><br>")

Response.Write "Last Modified：21/08/2004<br>"

Response.Write("Author:<a href='http://blog.csdn.net/alonesword/' style='text-decoration:none' target='_blank'>AloneSword</a>")

Response.Write "</div>"

End Sub

小结：

最值得学习的还是response.End()的合理使用，非常的好。只要出现错误马上终止程序的运行，不给后面的机会，保证数据的安全。
