easy ui tree

action JSON的值是這樣的：
[color=red]{"systemMenuTreeList[/color]":[{"attributes":null,"children":[],"iconCls":null,"id":"282","state":"open","text":"test"},{"attributes":null,"children":[{"attributes":null,"children":[{"attributes":null,"children":[{"attributes":{"menuUrl":"dd"},"children":[],"iconCls":"ico-sub_menu","id":"1","state":"open","text":"系統管理"},{"attributes":{"menuUrl":"ee"},"children":[],"iconCls":"ico-sub_menu","id":"2","state":"open","text":"模組管理"},{"attributes":{"menuUrl":"ff"},"children":[],"iconCls":"ico-sub_menu","id":"3","state":"open","text":"父菜單管理"},{"attributes":{"menuUrl":null},"children":[],"iconCls":"ico-sub_menu","id":"4","state":"open","text":"子菜單管理"},{"attributes":{"menuUrl":null},"children":[],"iconCls":"ico-sub_menu","id":"5","state":"open","text":"用戶管理"},{"attributes":{"menuUrl":null},"children":[],"iconCls":"ico-sub_menu","id":"6","state":"open","text":"用戶權限管理"}],"iconCls":"icon-save","id":"1","state":"open","text":"系統管理"}],"iconCls":"icon-save","id":"1","state":"open","text":"系統管理"}],"iconCls":"ico-systems","id":"1","state":"open","text":"系統管理"},{"attributes":null,"children":[{"attributes":null,"children":[{"attributes":null,"children":[{"attributes":{"menuUrl":"www.baidu.com"},"children":[],"iconCls":"ico-sub_menu","id":"7","state":"open","text":"測試1"},{"attributes":{"menuUrl":"www.126.com"},"children":[],"iconCls":"ico-sub_menu","id":"8","state":"open","text":"測試2"},{"attributes":{"menuUrl":"cc"},"children":[],"iconCls":"ico-sub_menu","id":"9","state":"open","text":"測試3"}],"iconCls":"icon-save","id":"2","state":"open","text":"測試程序"}],"iconCls":"icon-save","id":"2","state":"open","text":"測試"}],"iconCls":"ico-systems","id":"2","state":"open","text":"測試"}]}

然後easy ui需要的JSON數據格式是：
[{
"id":1,
"text":"Folder1",
"iconCls":"icon-save",
"children":[{
"text":"File1",
"checked":true
},{
"text":"Books",
"state":"open",
"attributes":{
"url":"/demo/book/abc",
"price":100
},
"children":[{
"text":"PhotoShop",
"checked":true
},{
"id": 8,
"text":"Sub Bookds",
"state":"closed"
}]
}]
},{
"text":"Languages",
"state":"closed",
"children":[{
"text":"Java"
},{
"text":"C#"
}]
}]
