UglifyJS压缩js文件和jsp里面的js代码

如果你不知道UglifyJS就out了，jquery的官方压缩工具啦～
本来UglifyJS没有windows的客户端压缩工具，后来自己参照YUI的BAT工具（好像是淘宝一个哥们写的）改写了一个，具体见下面的说明。

自己修改后的：

UglifyJS


安装指南
=========

安装步骤：

0. 安装nodejs运行环境:http://nodejs.org/,设置nodejs的安装目录到PATH中，一句话CMD中输入 node --version：
--->C:\Users\xin>node --version
--->v0.6.15
1. 安装请点击 install.cmd
2. 卸载请点击 uninstall.cmd
3. 如果安装过之前的版本，请先卸载老版本


压缩测试：

选中 test.js, 执行右键菜单“Process with UglifyJS”，会生成 test-min.js.

注意需要nodejs环境，怎么安装？自己谷歌吧,还有jsp里面的script标签要标准哦，只能是:"<script>"和'<script type="text/javascript">'，其他的自己去写吧，text.indexOf('<script type="text/javascript">')

当然我觉得这个工具最好能支持压缩jsp里的js代码啦，所以自己看了下bin下面的uglifyjs文件，无非就是一些js的函数，找到了修改代码的切入点：output(squeeze_it(text))，接下来就好办了，下图为修改前后的对比：





最后看看实际效果图吧：



最后附上maven下面的压缩脚本：

我也自己做了个windows界面版的，没你们功能那么强大，就是批量压缩

<!-- 思路：打包直接把js和jsp压缩后复制到目的地，在war插件的复制里面，排除刚刚复制的js和jsp，这样就不会覆盖了。打包的时候也能打进去了。 -->

悲剧，搞了两天了，压缩后的文件始终不会自动打包到War里去。

可以修改下这个吧。
<phase>install</phase>

试过了。还是不行，目前还在找资料解决。

呵呵，是有这个问题，自己手动打包下就可以了。war就是个zip包。
