大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。
目前做了一个easyui项目需要显示多级菜单，菜单配置到数据库中，因此每级菜单都需要到数据库中取，用了jQuery EasyUI方便多了。

菜单项的json文件代码：
[ { "id": 1, "text": "Tree菜单", "children": [ { "id": 11, "text": "Photos", "state": "closed", "children": [ { "id": 111, "text": "<a href='http://hovertree.com'>何问起</a>" }, { "id": 112, "text": "<a href='http://hovertree.com/jeasyui/'>EasyUI</a>" }, { "id": 113, "text": "<a href='http://hovertree.com/menu/jquery/'>jQuery</a>" } ] }, { "id": 12, "text": "Program Files", "children": [ { "id": 121, "text": "<a href='http://hovertree.com/h/bjaf/hoverclock.htm'>HoverClock</a>" }, { "id": 122, "text": "<a href='http://hovertree.com/h/bjaf/easysector.htm'>画饼图</a>", "attributes": { "p1": "Custom Attribute1", "p2": "Custom Attribute2" } }, { "id": 123, "text": "<a href='http://hovertree.com/h/bjaf/hovertreebatch.htm'>批量重命名</a>" }, { "id": 124, "text": "<a href='http://tool.hovertree.com/a/base64/'>图像转码</a>", "checked": true } ] }, { "id": 13, "text": "<a href='http://hovertree.com/texiao/game/'>见缝插针</a>" }, { "id": 14, "text": "<a href='http://hovertree.com/shortanswer/bjaf/j43wyyvr.htm'>选择题</a>" }, { "id": 15, "text": "<a href='http://hovertree.com/h/bjaf/css3icon.htm'>图标</a>" }, { "id": 16, "text": "<a href='http://hovertree.com/h/bjaf/treeaction.htm'>原文</a>" } ] } ]
