我如何串连JavaScript文件合并成一个文件？ [英] How do I concatenate JavaScript files into one file?

问题描述

我要创建我的网站编译JavaScript文件。对于开发我想preFER保持的JavaScript在单独的文件，只是作为我的自动化脚本的一部分的文件连接成一个，在它运行的COM pressor。

I want to create a compiled JavaScript file for my website. For development I would prefer to keep the JavaScript in separate files and just as part of my automated scripts concatenate the files into one and run the compressor over it.

我的问题是，如果我使用旧的DOS复制命令它也使在EOF标记该COM pressor抱怨：

My problem is that if I use the old DOS copy command it also puts in the EOF markers which the compressor complains about:

拷贝/ A * .js文件compiled.js / Y

copy /A *.js compiled.js /Y

什么是其他人在做什么？

What are other people doing?

推荐答案

我建议使用Apache Ant和YUI的COM pressor。

I recommend using Apache Ant and YUI Compressor.

把这样的事情在Ant构建XML。
这将创建两个文件的application.js和应用程序min.js。

Put something like this in the Ant build xml. It will create two files, application.js and application-min.js.

<target name="concatenate" description="Concatenate all js files">
    <concat destfile="build/application.js">
        <fileset dir="src/js" includes="*.js" />
    </concat>
</target>

<target name="compress" depends="concatenate" description="Compress application.js to application-min.js">
    <apply executable="java" parallel="false">
        <filelist dir="build" files="application.js" />
        <arg line="-jar" />
        <arg path="path/to/yuicompressor-2.4.2.jar" />
        <srcfile />
        <arg line="-o" />
        <mapper type="glob" from="*.js" to="build/*-min.js" />
        <targetfile />
    </apply>
</target>
