Question

我有这个windows batch文件，可以简化前端开发人员的工作：

@echo off
echo.

set NEW_COMPONENT=%1
set NEW_COMPONENT=%NEW_COMPONENT:/=\%
set NEW_COMPONENT_TO_SPLIT=%NEW_COMPONENT:/= %

REM get the component name (last item form '/' spearated array)
for %%a in ("%NEW_COMPONENT_TO_SPLIT%") do set "COMPONENT_NAME=%%~nxa"

set HTML=src\%NEW_COMPONENT%\%COMPONENT_NAME%.html
set SCSS=src\%NEW_COMPONENT%\_%COMPONENT_NAME%.scss
set JS=src\%NEW_COMPONENT%\_%COMPONENT_NAME%.js
set IMG=src\%NEW_COMPONENT%\img

mkdir src\%NEW_COMPONENT%
echo | set /p x=created folder: src\%NEW_COMPONENT%\

echo. 2>%HTML%
echo | set /p x=created file: %HTML%

echo. 2>%SCSS%
echo | set /p x=created file: %SCSS%

echo. 2>%JS%
echo created file: %JS%

mkdir %IMG%
echo | set /p x=created folder: %IMG%\

echo.

现在，他们要求我将import %COMPONENT_NAME% from '%PARENT_COMPONENT';字符串放入父组件.js文件的第一行，以自动链接新组件和父组件。

用户可以这样使用：

create-component.bat components/header/nav

在这种情况下，%COMPONENT_NAME%将是nav，但如何才能在上一个项目之前捕获该项目？在这种情况下，它将是header

Answer 1

for可以使用相对路径。因此components\header\nav\..与components\header相同。从该路径中，您需要最后一个元素%%~nxA：

set "NEW_COMPONENT_TO_SPLIT=components\header\nav"
for %%A in ("%NEW_COMPONENT_TO_SPLIT%\..") do set "COMPONENT_NAME=%%~nxA"
echo %COMPONENT_NAME"

Answer 2

将您的for循环部分更改为此（修改后的第一循环和添加的行）：

for %%a in ("%NEW_COMPONENT_TO_SPLIT%") do set "COMPONENT_TMP=%%~pa"
for %%i in ("%COMPONENT_TMP:~0,-1%") do set "COMPONENT_NAME=%%~nxi"

因此，您的修订脚本：

@echo off
echo.

set NEW_COMPONENT=%1
set NEW_COMPONENT=%NEW_COMPONENT:/=\%
set NEW_COMPONENT_TO_SPLIT=%NEW_COMPONENT:/= %

REM get the component name (last item form '/' spearated array)
for %%a in ("%NEW_COMPONENT_TO_SPLIT%") do set "COMPONENT_TMP=%%~pa"
for %%i in ("%COMPONENT_TMP:~0,-1%") do set "COMPONENT_NAME=%%~nxi"

set HTML=src\%NEW_COMPONENT%\%COMPONENT_NAME%.html
set SCSS=src\%NEW_COMPONENT%\_%COMPONENT_NAME%.scss
set JS=src\%NEW_COMPONENT%\_%COMPONENT_NAME%.js
set IMG=src\%NEW_COMPONENT%\img

mkdir src\%NEW_COMPONENT%
echo | set /p x=created folder: src\%NEW_COMPONENT%\

echo. 2>%HTML%
echo | set /p x=created file: %HTML%

echo. 2>%SCSS%
echo | set /p x=created file: %SCSS%

echo. 2>%JS%
echo created file: %JS%

mkdir %IMG%
echo | set /p x=created folder: %IMG%\

echo.

如何在Windows批处理中获取分割字符串的最后一个元素？
