easyui高级控件
开发模式
1、
美工（ui工程师：出一个项目模型）
java工程师：将原有的html转成jsp，动态展示数据
缺点：
客户需要调节前端的展示效果
解决：由美工去重新排版，重新选色。
2、
前后端分离
美工、java工程师都是独立工作的，彼此之间在开发过程中是没有任何交际。
在开发前约定数据交互的格式。
java工程师的工作：写方法返回数据如tree_data1.json
美工：只管展示tree_data1.json
JSON文件：

{"uid":"FI-SW-01","uname":"Koi","upwd":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
