python递归实现Easyui combotree树

自动化发布系统在选择文件时，使用jQuery EasyUI 创建页面树形菜单(Tree) 及后端python 递归实现Easyui combotree 树。这里主要分享2点：

1、linux 中 python 递归实现Easyui combotree 树

2、jQuery EasyUI就不用介绍了，一款轻量级UI框架，集成了各种用户界面插件。

关于jQuery EasyUI 可以参考： http://www.w3cschool.cc/jeasyui/jqueryeasyui-tutorial.html

关于自动化发布系统，可以查看：http://www.huangdc.com/13

本文环境基础：http://www.huangdc.com/21

目的：用户在页面选择对应项目，前端展示对应项目svn目录列表

废话不多说，先上图看看UI

选择项目时，展示项目目录的 tree

jQuery EasyUI tree 代码 html

##需要调用easyui.css 和 jquery.easyui.min.js
