Question

我正在尝试制作一个批处理文件，用于打开python文件，来自竞争，在notepadd ++中。不同的阶段有不同的任务。它允许您选择年份和阶段。它还允许您打开它们才能查看。最后认为它会询问您是否要创建丢失的文件。我正在使用exists来检查文件是否存在，notepad ++会自动询问您是否要创建丢失的文件，我想避免这种情况。

@echo off
echo What stage?
SET /p etap=
echo What year?
SET /p rok=
echo Edit? [y/n] ::Open as read only or not. 
SET /p mode=

if %mode%==y (
    echo Create missing files? [y/n]
    SET /p missing=
    if %missing%==y (

当我运行文件时，它会先询问3个问题并关闭。我认为这是因为括号。

Answer 1

在解析（parnethesis）块之前，在执行代码之前完成百分比扩展时，它会失败。

因此%missing%会扩展到执行行if %mode%==y (之前的值。

为避免这种情况，您可以使用延迟扩展。

setlocal EnableDelayedExpansion

...
if !mode!==y (
    echo Create missing files? [y/n]
    SET /p missing=
    if !missing!==y (
...
