asp中將相對路徑轉換為絕對路徑的函數代碼

代碼如下:
'================================================
' 函數名：ChkMapPath
' 作 用：相對路徑轉換為絕對路徑
' 參 數：strPath ----原路徑
' 返回值：絕對路徑
'================================================
Function ChkMapPath(ByVal strPath)
Dim fullPath
strPath = Replace(Replace(Trim(strPath), "/", "\"), "\\", "\")

If strPath = "" Then strPath = "."
If InStr(strPath,":\") = 0 Then
fullPath = Server.MapPath(strPath)
Else
strPath = Replace(strPath,"..\","")
fullPath = Trim(strPath)
If Right(fullPath, 1) = "\" Then
fullPath = Left(fullPath, Len(fullPath) - 1)
End If
End If
ChkMapPath = fullPath
End Function
