批次:如何提示输入,如果超时则继续? [英] Batch: How to prompt for input and continue if timed out?
问题描述
我知道 timeout/t 60
的方式来获得自动继续的延迟,并且 set/p var ="prompt"
来获取用户输入,但是有什么办法吗?改变两者兼而有之;问,如果没有输入任何内容,则有超时时间可以继续吗?我将其用于循环脚本的获取设置"屏幕,以更改脚本设置.
I know the timeout /t 60
way to get a delay with automatic continue and the set /p var="prompt"
for getting user input but is there any change to do both; ask and have a timeout to continue if nothing is entered? I would use it for a sort of get set screen for my looping script to change script settings.
推荐答案
看看 choice/?
以请求密钥并因超时而中止.
Take a look at choice /?
to request a key and abort with a timeout.
例如:
CHOICE /T 10 /C YN /D Y
将等待10秒钟以等待Y(是)或N(否),否则将采用默认值(/D),在本示例中为Y(是).
will wait 10 seconds for Y (Yes) or N (No), otherwise the default (/D) will be taken, which is Y (Yes) in this example.
要检查结果(按键或默认值),必须检查%ERRORLEVEL%
.
To check the result (either keypressed or default value), you have to check %ERRORLEVEL%
.
@echo off
cls
CHOICE /T 5 /C YN /D Y
set _e=%ERRORLEVEL%
if %_e%==1 echo Y&goto :done
if %_e%==2 echo N&goto :done
echo Error
echo %_e%
:done
