Enter Menu Number: [1,2,3]?1
Folder Name:joje
A subdirectory or file joje already exists.
Successful!

为什么成功！"被呼应吗?因为它只会在进入:create folder 命令时提示..pls帮助我:( ..btw我的操作系统是win7
================================================== =================================
:MyFolder
选择/C 123/M输入菜单编号:"
如果错误级别为1，则转到1
如果错误级别2转到2
如果错误级别3转到3

:1
设置/p folderName =文件夹名称:
如果不存在''％folderName％''转到:createFolder

:createFolder
md％folderName％
回声成功！
暂停> nul
goto myFolder

why "Successful!" is echoed? since it will only prompt if it goes to :create folder command..pls HELP me :( ..btw my OS is win7
====================================================================================
:MyFolder
Choice /C 123 /M "Enter Menu Number:"
If errorlevel 1 Goto 1
If errorlevel 2 Goto 2
If errorlevel 3 Goto 3

:1
set /p folderName=Folder Name:
if not exist ''%folderName%'' goto :createFolder

:createFolder
md %folderName%
echo Successful!
pause > nul
goto myFolder

推荐答案

我看不出它是怎么做到的.如果没有转到:createFolder，它将掉入:createFolder.然后它将回显成功".没有办法不这样做.

I don''t see how it could not do that. If it doesn''t goto :createFolder, it will fall through to :createFolder. Then it will echo ''successful''. There''s no path for it not to do that.

:createFolder
set /p folderName=Folder Name:
if exist %folderName% goto :error else :yes

md %folderName% (I just have to take this command line out in the :Yes command, strange isn't it?)

:yes
echo The folder %folderName% created successfully!
pause > nul
goto :1
exit

:error
echo The folder %folderName% already exist!
Pause > nul
goto :1
exit
