Windows 批处理文件菜单程序意外关闭

我两天前开始编写代码，想制作一个基于菜单的程序，在其中输入提示

不知怎的，在第14行之后，程序关闭了，我不知道为什么

如果有人能解释为什么我的代码不起作用，而不是发布全新的代码，那就太棒了

echo off
:c
color fa
echo ====================================
echo =      WELCOME!I AM LIZA!          =
echo =      HOW ARE YOU TODAY?          =
echo =    1) Im great :D                =
echo =    2) Im okay :I                 =
echo =    3) Im sad :(                  =
echo =                                  =
echo ====================================
echo.
echo.
set /p ans="Enter your number to continue:"

if %ans%==1(
goto a1
)
if %ans%==2(
goto a2
)
if %ans%==3(
goto a3
)

:a1
cls
echo Liza: Nice to hear so! :D What did you do today?
echo.
set /p ans=">> "
cls
echo Liza: Sounds awesome! I was swimming in millions of bits today, it was so fun! xD
pause

:a2
cls
echo Liza: You dont seem like... What happened that makes you feel unconfy? ;(
echo.
set /p ans=">> "
cls
echo Liza: Im sorry for that, I hope talking to me makes it better tho ;)
pause

:a3
cls
echo Liza: Why so?! Tell me what or who makes you sad, im here for you to cheer you up!
echo.
set /p ans=">> "
cls
echo Liza: Oh my god, thats terrible im so sorry for you! I hope you feel better after talking to me, because im a software that is just nice :D
pause
```

您的具体问题是，在右括号之前没有包含空格字符

不正确：

if %ans%==1(

正确：

if %ans%==1 (

更正确的是：

if "%ans%" == "1" (

但是，您应该替换整个带标签的

：c

部分，以使用更合适的命令，如下所示：

Color FA
Echo ====================================
Echo =      WELCOME!I AM LIZA!          =
Echo =      HOW ARE YOU TODAY?          =
Echo =    1) Im great :D                =
Echo =    2) Im okay :I                 =
Echo =    3) Im sad :(                  =
Echo =                                  =
Echo ====================================
Echo(
Echo(
Choice /C 123 /N /M "Enter your number to continue:"
GoTo a%ErrorLevel%

我还建议，由于您似乎有意对所有不必要的内容发出惊叹声，您应该以

@Echo Off&SetLocal EnableExtensions DisableDelayedExpansion开始脚本，而不是
Echo Off
。当前启用了延迟扩展，不管是意外还是其他原因，您的感叹号，
可以被删除，或者更糟糕的是，像这样的东西：
Echo=WELCOME！我是莉莎=，将扩展为
=WELCOME=
。最安全的方法，尤其是当你需要在脚本中的任何地方使用延迟扩展时，当然是完全不要使用感叹号。非常感谢大家！这帮了我很大的忙，我是一个初学者，这对我来说是全新的。谢谢你帮了我的忙！：D
