Question

当我在下面的代码中键入变量并按下输入代码时，我的问题就出现了问题，但是如果我再次按Enter键，即使屏幕已被清除，它也会读取相同的代码。

:type
set /p menu=type:

    if /i "%menu%" == "go north" goto north
    if /i "%menu%" == "go south" goto south
    if /i "%menu%" == "go east" goto east
    if /i "%menu%" == "go west" goto west
    echo %name%, that command does not exist.
    pause
    cls
    goto play

您必须重置变量menu，否则它将保持定义：

:type
set menu=
set /p menu=type:

if /i "%menu%" == "go north" goto north
if /i "%menu%" == "go south" goto south
if /i "%menu%" == "go east" goto east
if /i "%menu%" == "go west" goto west
echo %name%, that command does not exist.
pause
cls
goto play

set / p menu = type：ghost变量
