最近用项目中用ext的一些东西，其中desktop这个是第一次用做个记录。其中开始菜单动态生成花了一天的时间，现在想想一开始把问题复杂化了，把自己做的东西拿出来，希望能给以后的同学一点建议。代码是在ext2的例子sample.js上改的

下面说一下多级菜单的快捷方式的做法，
<dt id="tab-win-shortcut">
<a href="#"><img src="images/im48x48.png" />
<div>Accordion Window</div></a>
</dt>
这个是例子中定义快捷方式的代码，这个只能支持一级的菜单，现在在这个上面修改
<dt id="multi-menu-shortcut" rmid="rootMenu">
<a href="#"><img src="images/im48x48.png" />
<div>multi-menu Window</div></a>
</dt>
多了一个rmid，这个是多级菜单的根菜单的id。这里就要在Desktop.js做一些修改，
shortcuts.on('click', function(e, t){
if(t = e.getTarget('dt', shortcuts)){
e.stopEvent();
var module = app.getModule(t.id.replace('-shortcut', ''));
if(module){
module.createWindow();
}
//---多级菜单快捷方式--
else
{
var rm = e.getTarget('dt', shortcuts).attributes.rmid.value;//对应的rmid 根菜单module id
var rmmodule = app.getModule(rm);
var str = t.id.replace('-shortcut', '');
var temp=Ext.getCmp(str);//获取本菜单对象
rmmodule.createWindow(temp);
}
//---多级菜单快捷方式--
}
});
附件是全部的代码，需要的可以看一下，放到要自己添加ext支持。
效果如图
