vbscript - vbscript中下标超出范围错误

Question

有人可以看看下面的脚本并告诉我为什么它在 vbscript 中抛出此错误下标超出范围错误。在文本文件中，它有两个条目正确写入文件，但随后在退出时抛出错误循环，因此它永远不会调用其他函数..我认为它尝试运行 3 次，但文本文件中只有 2 个条目

The text file is in this format

    Format.css Shared
    Design.css Shared


Dim strInputPath1
Dim txsInput1,txsOutput
Dim FSO
Dim Filename

Set FSO = CreateObject("Scripting.FileSystemObject")
strOutputPath = "C:\txt3.txt"
Set txsOutput = FSO.CreateTextFile(strOutputPath)

Set re = New RegExp
re.Pattern = "\s+"
re.Global  = True

Set f = FSO.OpenTextFile("C:\Users\spadmin\Desktop\Main\combination.txt")
Do Until f.AtEndOfStream
  tokens = Split(Trim(re.Replace(f.ReadLine, " ")))
  extension = Split(tokens(0),".")
  strInputPath1 =  "C:\inetpub\wwwroot\Test\files\" & tokens(1) & "\" & extension(1) & "\" & tokens(0) 
  Set txsInput1 = FSO.OpenTextFile(strInputPath1, 1)
  WScript.Echo strInputPath1
  txsOutput.Writeline txsInput1.ReadAll

Loop
WScript.Echo "Calling"

txsInput1.Close
txsOutput.Close
f.Close
Call CreateCSSFile()

如果您的文件包含尾随空白行，则应用 Split() 可能会返回元素少于 2 个的数组。在这种情况下，token(1) 应该抛出“下标超出范围”错误。

您应该始终检查 Split() 是否按预期工作:

tokens = Split(Trim(re.Replace(f.ReadLine, " ")))
If 1 = UBound(tokens) Then
   extension = Split(tokens(0),".")
   If 1 = UBound(extension) Then
      strInputPath1 =  "..." & tokens(1) & "..." 
   Else
      ... parse error ...
   End If
Else
   ... parse error or just trailing blank lines? ...
End If
