用Ext3.0的API主页框架做的项目

最近一段时间公司里没有项目，有空就专研ext，顺便用它完成了一个小项目。Ext API的主页就是一个典型的tab框架，通过它可以创建如同FireFox浏览器一样，打开一个页面就往上面添加一个tab，方便用户的使用，可以在同一个浏览器中浏览多个页面。
左边是一个树形结构的菜单，右边是一个tab的页面，左边菜单的代码为

]};

        Docs.icons = {
       
"book":"icon-cls"
,
"company":"icon-cmp"
,
"department":"icon-cls"
,
"user":"icon-cmp"
,
"business":"icon-cls"
,
"subject":"icon-cls"
,
"class":"icon-cmp"
};
    这是菜单的结构，我没有全部改源码，只改成了连接到我的jsp页面，iconCls属性还是和原来的一样。

这个添加tab也只修改了一些地方，还没有简化到最优。由于项目大于10M没法上传，如有需要请留言。
