用IF+GOTO写的````

@echo off
set a=10
echo %a%
:first
if %a% gtr 0 goto home else goto end
:home
set /a a=%a%-1
echo %a%
if %a% gtr 0 goto first else goto end
:end
pause

@echo off
for /l %%a in (10 -1 1) do (
echo %%a && ping 127.1 -n 2 >nul
)
echo    按任意键退出！
pause>nul
复制代码

我先用ping 1 -n 1 -w 1000 >nul来计时，发现倒计时显示完的用时超过10s，而用ping 127.1 -n 2 >nul在10s左右，想来用这样的倒计时应该都会比10s多一些用时吧。

@echo off
set var=10
:loop
echo %var%
set /a var-=1
ping -n 2 127.1>nul
if %var% neq 0 goto loop
pause>nul

@echo off
for /l %%a in (10,-1,1) do (
  echo %%a
  ping -n 2 127.1 >nul
  cls
)
pause>nul
复制代码

或者：

@echo off
set "a=10"
:Start
echo %a%
ping -n 2 127.1>nul & cls
set/a a-=1
if %a% gtr 0 goto Start
pause>nul
复制代码

第一种最笨的方法：
@echo off
for  %%i in (10,9,8,7,6,5,4,3,2,1,0) do (
       echo %%i
)
pause

pumahxh

@echo off&cls
for /l %%i in (10,-1,1) do (
    echo 倒计10秒：%%i
    ping -n 2 127.1>nul
    cls )
pause>nul
复制代码

看了下，早已有人用此法了。

ghostwar

@echo off
set "war=198989"
set/p "aaa=请输入密码"
if  "%aaa%" equ " war" echo (登陆成功！）else (登陆失败！）
pause

@echo off
setlocal enabledelayedexpansion
set a=10
for /l %%i in (1,1,10) do (
    set a=11    
    set /a a-=%%i
    echo !a!
)
pause

这样也可以，呵呵

想问楼主如果我想让他只循环出现3次该怎么做
