當用戶輸入標籤時如何轉到另一個批處理文件中的標籤

Question

當用戶輸入文章ID爲「512」或「515」時，轉到article.bat中的標籤，然後顯示消息。

main.bat

@echo off 
set /p a="Enter Article ID: " 
call article.bat :%a% 

article.bat

:512 
echo You see the 512 
:515 
echo You see the 515 

Answer 1

嘗試增加GOTO％1 Article.bat的開始。

GOTO %1 

:512 
echo You see the 512 
:515 
echo You see the 515 

請注意，如果輸入「512」，它將顯示這兩個消息，因爲它不會在下一個標籤之前退出。

Answer 2

這種方法有一定的優勢：

main.bat

@echo off 
set /p a="Enter Article ID: " 
call :%a% 2>NUL 
if errorlevel 1 (
    echo No such article 
) else (
    echo Returned from article.bat 
) 
goto :EOF 

:512 
:515 
article.bat 

article.bat

:512 
echo You see the 512 
exit /B 0 

:515 
echo You see the 515 
exit /B 0
