今天偶然间看到文档服务器有一个动态目录功能，点击目录能跳转到指定的位置；窗口滑动也能自动更新目录的焦点。
效果
框架
原来使用的是一个开源的jquery-ui控件——tocify.js，它可以遍历页面，把指定的DOM元素抽取出来形成目录。
下载地址参考gitub : [gfranko/jquery.tocify.js]
开发者可以直接下载zip包使用，压缩包里面的内容包括：
- demos 演示页面（里面有一个google的链接，访问会超时，去掉即可）
- images 可以忽略
- libs 额外使用的文件，如jquery,jquery-ui,bootstrap等等
- src 源文件（包括js以及css）——重点
- test 忽略
- 其他忽略
举个栗子

效果就像前面flash中一样
