UglifyJS壓縮jsp裏面的js代碼和js文件

若是你不知道UglifyJS就out了，jquery的官方壓縮工具啦～ 

原本UglifyJS沒有windows的客戶端壓縮工具，後來本身參照YUI的BAT工具（好像是淘寶一個哥們寫的）改寫了一個，具體見下面的說明。

UglifyJS
安裝指南
=========
安裝步驟：
0. 安裝nodejs運行環境:http://nodejs.org/,設置nodejs的安裝目錄到PATH中，一句話CMD中輸入 node --version：
--->C:\Users\xin>node --version
--->v0.6.15
1. 安裝請點擊 install.cmd
2. 卸載請點擊 uninstall.cmd
3. 若是安裝過以前的版本，請先卸載老版本
壓縮測試：
選中 test.js, 執行右鍵菜單「Process with UglifyJS」，會生成 test-min.js.

jsp裏面的script標籤只能是:"<script>"和'<script type="text/javascript">'，其餘的本身加入吧，查找代碼：text.indexOf('<script type="text/javascript">') 

固然我以爲這個工具最好能支持壓縮jsp裏的js代碼啦，因此本身看了下bin下面的uglifyjs文件，無非就是一些js的函數，找到了修改代碼的切入點：output(squeeze_it(text))，接下來就好辦了，下圖爲修改先後的對比：

最後附上maven下面的壓縮腳本：
