batch-file - 批量变量

问题描述

我正在尝试创建一个可以根据选择以如下方式处理变量的代码：

set item1=ring
set item2=deadhead
set item3=bloodstainedmap
set item4=strangebox
cls
echo 1) %item1%
echo 2) %item2%
echo 3) %item3%
echo 4) %item4%
echo. 
echo Which Item do you wish to look at?
choice /c 1234 /n >nul
if %errorlevel%==1 goto itemin
if %errorlevel%==2 goto itemin
if %errorlevel%==3 goto itemin
if %errorlevel%==4 goto itemin

:itemin
cls
echo %item%errorlevel%%
::^^^^ this part here should read "ring" if i selected 1. It reads "errorlevel"

显然，我希望项目在加载变量时正确显示....

有什么帮助吗？

解决方案

作为@Mofi答案的补充：

Choice 命令可以在 for /F 循环中执行，允许直接使用选择选项，而不是评估错误级别。必须使用 /N 无提示开关，必须排除使用 /M 自定义提示开关。

获取实际按键而不是错误级别的语法是：

@ECHO Off & Goto :main
