easyui的datagrid和treegrid的使用

 $('#listTree').treegrid({
              idField: 'id',
              treeField: 'menuName',
              columns: [[
                
                  { title: 'Task Name', field: 'menuName',  180 },
                  { field: 'menuUrl', title: 'progress',  60, align: 'right' }

              ]]
             
          });
          var data = { "total": 3, "rows": [{ "id": 0, "menuName": "管理员首页", "menuUrl": "/main/admin/index.action", "menuPCode": -1, "isLeaf": "0", "status": "1", "icon": "", "createUser": "system", "createDate": "2014-01-24 17:10:25", "modifyUser": "system", "modifyDate": "2014-01-24 17:10:25" }, { "id": 1, "menuName": "修改密码", "menuUrl": "/main/admin/modifyPwd.action", "menuPCode": 0, "isLeaf": "1", "status": "1", "icon": "", "createUser": "system", "createDate": "2014-01-24 17:10:25", "modifyUser": "system", "modifyDate": "2014-01-24 17:10:25", "_parentId": 0 }, { "id": 2, "menuName": "图片上传", "menuUrl": "/image/admin/uploadImage.action", "menuPCode": 1, "isLeaf": "1", "status": "1", "icon": "", "createUser": "system", "createDate": "2014-01-24 17:10:25", "modifyUser": "system", "modifyDate": "2014-01-24 17:10:25", "_parentId": 1 }], "footer": [{ "name": "Total Persons:", "persons": 7, "iconCls": "icon-sum" }] };
          $("#listTree").treegrid('loadData', data);


          $('#list').datagrid({
               1000,
              height: 500,
              columns: [[

                  { title: 'Task Name', field: 'menuName',  180 },
                  { field: 'menuUrl', title: 'menuUrl',  60, align: 'right' }

              ]]
          
          });
          var data = { "total": 3, "rows": [{ "id": 0, "menuName": "管理员首页", "menuUrl": "/main/admin/index.action", "menuPCode": -1, "isLeaf": "0", "status": "1", "icon": "", "createUser": "system", "createDate": "2014-01-24 17:10:25", "modifyUser": "system", "modifyDate": "2014-01-24 17:10:25" }, { "id": 1, "menuName": "修改密码", "menuUrl": "/main/admin/modifyPwd.action", "menuPCode": 0, "isLeaf": "1", "status": "1", "icon": "", "createUser": "system", "createDate": "2014-01-24 17:10:25", "modifyUser": "system", "modifyDate": "2014-01-24 17:10:25", "_parentId": 0 }, { "id": 2, "menuName": "图片上传", "menuUrl": "/image/admin/uploadImage.action", "menuPCode": 1, "isLeaf": "1", "status": "1", "icon": "", "createUser": "system", "createDate": "2014-01-24 17:10:25", "modifyUser": "system", "modifyDate": "2014-01-24 17:10:25", "_parentId": 1 }], "footer": [{ "name": "Total Persons:", "persons": 7, "iconCls": "icon-sum" }] };
          $("#list").datagrid('loadData', data);

需要注意的是：data的数据，不是json字符串，是json对象
