批 - 如果，ElseIf，Else [英] Batch - If, ElseIf, Else

问题描述

这段代码有什么问题？

IF "%language%" == "de" (
    goto languageDE
) ELSE (
    IF "%language%" == "en" (
    goto languageEN
) ELSE (
    echo Not found.
)

我在批处理方面不是很好..

I'm not really good in Batch..

推荐答案

@echo off
title Test

echo Select a language. (de/en)
set /p language=

IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN

echo Not found.
goto commonexit

:languageDE
echo German
goto commonexit

:languageEN
echo English
goto commonexit

:commonexit
pause

重点是批量只是继续通过指令，逐行直到达到 goto ，退出或end-of-file。它没有部分的概念来控制流量。

The point is that batch simply continues through instructions, line by line until it reaches a goto, exit or end-of-file. It has no cencept of sections to control flow.

因此，输入 de 会跳转到：languagede 然后只需继续执行指令，直到文件结束，显示 de 然后 en 然后找不到。

Hence, entering de would jump to :languagede then simply continue executing instructions until the file ends, showing de then en then not found.
