                        handler:function(){
                            dlg.hide();
                        }
                    }]
            });
        }
        dlg.show(eDom);

        if(cfg.type=='m'){
            clearFormData();
            loadFormData(cfg.record);
        }
        //dlg.center();
    }

}

}();
Ext.onReady(Ext.kehu.Layout.Main.initPage.init,Ext.kehu.Layout.Main.initPage,true);
[/code]

这是action中部分代码
[code="java"]
System.out.println("有记录");
jsonResult = "{\"totalCount\":" + list.size() + ",\"success\":true,\"data\":" + jsonArray.toString() + "}";
response.setCharacterEncoding("UTF-8");
response.getWriter().write(jsonResult);
System.out.println(jsonResult);
response.getWriter().flush();
[/code]
现在问题是在action中可以得到数据，但就是不显示，请问如何修改，请同仁帮帮我，这是别人做好的东西我改成我要用的，查询他就没做
[b]问题补充：[/b]
ds的autoload加在什么位置呢？最好给个具体的例子

Answer 1

如果没有其他代码错误的话,ds加上autoLoad:true 配置项,页面打开后数据就显示了.你的代码里没有调用过ds的load.
