批处理：通过一个变量的值访问另一个变量

Question

如果标题令人困惑，我深表歉意。这是我的批处理脚本：

set var=1
set ss=var rem // ss is mean to be string
call :func %ss%
goto :eof

:func
    rem // I want to access to value 1 by using %1, which is ss

有什么办法吗？如果您提供一些帮助，我将不胜感激^v^

Answer 1

您可以使用延迟扩展。

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set var=1
set ss=var rem // ss is mean to be string
call :func %ss%
goto :eof

:func
    REM I want to access to value 1 by using %1, which is ss
    set a=%1
    REM will output '1'
    echo !%a%!

评价：!%a%! => !var! => 1
