使用如果批处理语句文件

Question

我有一批脚本（约书亚仿照在“战争游戏”）

@echo off 
color 0b 
echo Greetings, Professor Falken 
set /p interface = 
echo Would You Like to Play a Game? 
set /p ifGame = 
if /i "%ifGame%" =="yes" goto yesgame 
if /i "%ifGame%" =="no" goto nogame 
:yesgame 
echo List of Games 
echo chess 
echo Poker 
echo Fighter Combat 
echo Guerilla Warfare 
echo Desert Warfare 
echo Air-to-Ground Actions 
echo Theaterwide Tactical Warfare 
echo Theaterwide Biotoxic and Chemical Warfare 
echo Global Thermonuclear War 
pause 
echo Which game would you like to play? 
set /p WhichGame = 
pause 
exit 
:nogame 
set /p areYouSure=Are You Sure? 
pause 
exit 

但是，当我进入“否”它仍然显示的游戏列表...

Answer 1

使用set /p时，需要删除变量名称和=符号之间的空格。来源：

set /p ifGame = 

要：

set /p ifGame= 

否则你设置的变量在名字的后面加上一个空格。因此%ifGame%扩展为空，而%ifGame %将扩展为正确的值。
