项目使用 springmvc4.x spring4.x hibernate4.x easyui
为了便于开发，扩展了easyui 的 datagrid 功能，下面直接贴上扩展代码：
具体的实现项目可见 ： https://git.oschina.net/alexgaoyh/alexgaoyh.git
/**
* context 指定为 项目上下文
* index 如果定义多组dataGrid，index指定为对应的参数：一组dataGrid包含（datagrid;toorbar;dialog;button）
* templateUrl 指定为 此次访问操作对应的controller路径
* crud 指定为 对应的toorbar包含什么操作；crud：增加修改删除; c：增加; u：修改; d：删除;

只需要在页面中 创建一个对象： 并调用init方法即可；
var dg1 = new DataGridEasyui(context_, 1 , templateUrl, 'crud');
dg1.init();列表页对应的元素为 id="dg-1"的datagrid + id="toolbar-1"的toolbar
新增/修改对应的元素为 id="dlg-1"的dialog + id="dlg-buttons-1"的button
效果图如上，具体的代码可见git : https://git.oschina.net/alexgaoyh/alexgaoyh.git
