当输入的值错误时，我的批处理会通知用户并提供两个选项：重新输入值或退出程序。
@echo off
cls
setlocal enabledelayedexpansion
set /p _Value=Enter the value:
for /f skip^=4 %%e in ('echo;prompt $E^|cmd')do set "_$E=%%e"
if "!_Value!" gtr "10" (
echo %_$E%[31mInvalid value! Do you want to re-enter the value? (y=yes/n=exit) %_$E%[0m
IF /i "!r!"=="y" goto RELOADSAMESCREEN
goto :eof
)
当选择重新输入选项时，我设法使消息消失的唯一方法是重新加载相同的屏幕，因为当重新加载屏幕时，CLS 命令会清除屏幕上的消息，然后再次加载屏幕，因此消息会从屏幕上消失，用户可以重新输入值而不会出现错误消息。
如何才能清除 echo 命令发送的消息而不必重新加载同一屏幕？
已编辑：
根据@iTwasnTme 的回答，脚本进行了更改，现在好多了，但是输入字段在屏幕上不断重复，并且颜色不会恢复为白色。
更改的脚本：
@echo off
setlocal enabledelayedexpansion
for /f skip^=4 %%e in ('echo;prompt $E^|cmd')do set "_$E=%%e"
:RELOADSAMESCREEN
color & echo\& set /p "_Value=Enter the value: "
if !_Value! gtr 10 =;(
set /p "r=!_$E![31mInvalid value^!! Do you want to re-enter the value? [y=yes |or| n=exit] "
if /i "!r!"=="y" (set /p "'=!_$E
