easyui datagrid plunges 扩展 插件

    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
