extjs4 利用AJAX加载的数据封装到store中

1.利用AJAX加载的数据封装到store中
项目开发遇见的问题。
将ajax检索的结果加入到store中去
代码片

1.ajax

var t = Ext.getCmp("title_cn").value;
                	Ext.Ajax.request({
                		url : "./system/flfgzyk/flfg/solrquery.action",  
			    		method : "post",
			    		params:{
			    			t:t
	        			},
	        			success : function(response, opts){
	        				//从后台获取json数据，进行解析
	        				 var data = Ext.decode(response.responseText);
	        				//找到定位加载页面
	        				var grid=Ext.getCmp("gnxh341id");
	        				//数据放入store里面加载 信息
	        				grid.store.loadData(data.jsonarray);
	        			},
	        			failure: function(response, opts) {
	        				Ext.Msg.alert('系统提示',"查询失败！请与管理员联系");
	        			}
			    	});

2.store

var pageSize = 100;
Ext.define("fgql.xxfggl.store.xxfgglStore",{
	extend:"Ext.data.Store",
	model:"fgql.xxfggl.model.xxfgglModel",
	pageSize:pageSize,
	proxy:{
			type:"ajax",
		api:{
			read:"/LFZXXT/system/fgql/xxfggl/getxxfgglcount.action"
		},
		reader:{			
	        type:"json",
			root:"jsonarray",
			totalProperty:"total"
		}
	},
	autoLoad:false
});
	

3.model

Ext.define("fgql.xxfggl.model.xxfgglModel",{
	extend:"Ext.data.Model",
