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
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.
点击加载按钮后也没有数据显示么?
最好用firebug在firefox上看一下客户端有没有得到数据或有没有解析错误
[code="java"]
ds=new Ext.data.Store({
proxy:new Ext.data.HttpProxy({url:'UserAction!getAllUser.action'}),
reader:new Ext.data.JsonReader({
id:'infoId',
root:'data',
totalProperty:'totalCount',
fields:[
{name:'infoId',type:'int'},
{name:'chePai',type:'string'},
{name:'beiBaoXianRen',type:'string'},
