爲什麼我的變量不能正確擴展

Question

我正在使用bat文件來處理數據庫，我的變量沒有正確擴展。

編輯：

我已經嘗試了上述暫時還沒有這樣的運氣。

這是必需的所有節目的代碼：

set n=0 

:1 
echo. 
set /p fname=Enter First Name: 
set /p lname=Enter Last Name: 
set /p val%n%=Enter E-mail: 
set /p num%n%=Enter Phone Number: 
set /p var%n%=Enter Service Number: 
set /p dvice%n%=Enter Device: 
set /p dserv%n%=Enter Date Serviced: 
set /p summ%n%=Enter Summary of Service: 
@echo set var%n%=!var%n%! > "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set val%n%=!val%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set fname=%fname% >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set lname=%lname% >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set dvice%n%=!dvice%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set dserv%n%=!dserv%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set summ%n%=!summ%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set num%n%=!num%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set n=%n% >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
echo. 
echo The data has been stored! 
echo. 
pause > nul 
goto start 

:2 
echo. 
echo LAST NAME IS CASE SENSITIVE! 
set /p lname=Please enter last name: 
echo. 
if /i not exist "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" (goto Error) 
call "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
echo First Name: %fname%  
echo Last Name: %lname% 
echo Device: !%dvice%%n%! 
echo Date of Service: !dserv%n%! 
echo. 
echo E-Mail: !val%n%! 
echo Phone: !num%n%! 
echo. 
echo Summary: 
echo. 
echo !summ%n%! 
echo. 
pause > nul 
goto start 

這是我所有的工作。 ％lname％.bat將變量存儲爲var0 =「變量值」問題在於它不讀取var0。它讀取！var 0 !.

Answer 1

調用腳本時，cmd的新實例正在運行。變量集僅適用於該實例。

set filepath=C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat 
for /f "delims=" %%a in (%filepath%) do %%a 

通過%lname%.bat每一行這將循環和運行線作爲命令 - 如果所有在%lname%.bat行的是那些組命令，這應該工作。

Answer 2

@ECHO OFF 
SETLOCAL ENABLEDELAYEDEXPANSION 
SET /a n=0 
:: call "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
:start 
call :plname 
echo First Name: %fname%  
echo Last Name: %lname% 
echo Device: !%dvice%%n%! 
echo Date of Service: !dserv%n%! 
echo. 
echo E-Mail: !val%n%! 
echo Phone: !num%n%! 
echo. 
echo Summary: 
echo. 
echo !summ%n%! 
echo. 
SET /a n+=1 
IF %n% lss 2 goto START 

GOTO :EOF 

:plname 
SET "fname=First name read" 
SET "lname=Last name read" 
SET "dvice0=Device zero" 
SET "dvice1=Device one" 
SET "dserv0=Date zero" 
SET "dserv1=Date one" 
SET "val0=Email zero" 
SET "val1=Email one" 
SET "num0=Phone zero" 
SET "num1=Phone one" 
SET "summ0=Summary zero" 
SET "summ1=Summary one" 
GOTO :EOF 

這批證明你的代碼確實有效。問題出在您的%lname%.bat，您尚未發佈。當然，您不會爲每個客戶設置不同的%lname%.bat？

發佈一些實際樣本數據沒有任何傷害 - 只需更改名稱以保護有罪。將實名修改爲「Brown」或「Green」或「Robinson」。似乎沒有人再使用這些名字 - 他們顯然是假的。
