[其他] [已解决]批处理单独一行出现的%1和%2是什么含义？

heyoug

%1 %2单独出现在一行中，并没有其他命令和参数，这个代表什么意思？
请看第三行......

代码执行到第5行的时候：
shellexecute("%~s0","goto :start","","runas",1)
会调用这个bat文件自身，并传递位置参数，那个时候 %1 %2 就有值了。

小渣飞

获取传值用的。

给您一个简单的示例，请把以下代码保存为“测试.bat”，放在D盘

@echo off

echo %%1的传值是 %1
echo %%2的传值是 %2
echo %%3的传值是 %3

pause
然后在cmd窗口中执行

D:\测试.bat 参数1 haha OKScript

第三行下面加一行：
echo,%1 %2
观察一下执行过程试试能看明白吗？
