Question

extjs3.2 (Ext.data.JsonStore 加载数据报错)

前台js:

var jobstore = new Ext.data.JsonStore({
autoLoad: true,
baseParams: { start: 1, limit: 15 },
root: 'datas',
totalProperty: 'totalCount',
proxy: new Ext.data.HttpProxy({
url: basePath + '/AjaxDone/UserDone.aspx?type=search',
method: 'POST'
}),
fields: [{ name: 'USER_ID' }, { name: 'PASSWORD' }, { name: 'USER_NAME' }],
listeners: {
exception: function () {
Ext.Msg.alert("错误", "数据加载出错！");
}
}

});

后台:

DataTable dt = new DataTable();
dt.Columns.Add("USER_ID");
dt.Columns.Add("PASSWORD");
dt.Columns.Add("USER_NAME");
DataRow dr = dt.NewRow();
dr["USER_ID"] = "c8217df88a084d03ade960ffc989b9cb";
dr["PASSWORD"] = "PASS";
dr["USER_NAME"] = "NAME";
dt.Rows.Add(dr);
List<Hashtable> list = comm.GetListByDataTable(dt);
string ss = serializer.Serialize(list);
string strJsonSource = @"{""totalCount"":""10";
strJsonSource = strJsonSource + @""",""datas"":" + ss + "}";
return strJsonSource;

返回值：

//{"totalCount":"10","datas":[{"USER_ID":"c8217df88a084d03ade960ffc989b9cb","PASSWORD":"PASS","USER_NAME":"NAME"}]}
