vbscript - 如何输出传递给 VBScript 脚本的参数列表？

Question

我有以下 VBScript 代码:

Dim returnVal
returnVal = "You did not pass me 4 arguments"

args = WScript.Arguments.Count

If args = 4 Then
    returnVal = "The arguements you passed me are " & WScript.Arguments.Item(0) & "  "  & WScript.Arguments.Item(1) & "  "  & WScript.Arguments.Item(2) & "  "  & WScript.Arguments.Item(3) 
end if

我想要的只是能够打印“returnVal”，这样如果我输入:

test.vbs 1 2 3 4

它将返回:

The arguments you passed me are 1 2 3 4

我该怎么做？

Answer 1

要输出到命令控制台窗口，您可以使用:

WScript.Echo returnVal 

或

WScript.StdOut.WriteLine returnVal 

但是您必须使用CScript主机才能使其工作，例如:

cscript.exe myscript.vbs

WScript 是 GUI 主机，因此不了解标准输入/输出/错误/辅助流。尝试执行 WScript.StdOut.WriteLine 将导致以下错误对话框:

---------------------------Windows Script Host---------------------------Script: d:\myscript.vbsLine:   12Char:   1Error:  The handle is invalid. Code:   80070006Source:     (null)---------------------------OK   ---------------------------

In a CScript.exe script you can still pop up GUI message dialogues using:

Msgbox "Hello World!" 

在 WScript 主机中使用 WScript.Echo 将在弹出对话框中显示消息，而不是打印到命令行窗口。

The difference between Cscript and Wscript is that Cscript is the command-line version of the script host and Wscript is the graphical version. This difference isn’t really noticeable unless your script uses the Wscript.Echo command.
