[ExtJS] JsonStore如何读取自定义数据？

Question

JSON数据格式：
         {
             username:"",
             sex:"",
             age:"",
             loginLogs:{
                 [lgoinTime:"2011-2-11 23:19:00",.....],
                 [lgoinTime:"2011-2-15 23:19:00",.....],
                 [lgoinTime:"2011-2-18 23:19:00",.....]
             }
         }JsonStore如下：    var  jsonStore = new Ext.data.JsonStore({
              url:"....."，//我就省略了
              render:new Ext.data.JsonReader({
                   root:'loginLogs',
                   fields:['loginTime','......']
              })
         });    jsonStore.load({
        params:{userid:'111'},
        callback:function(record){
            //请问此处如何获取username,sex,age的值？？？
        }
    });如何在回调函数中获取自己定义的数据项？谢谢！

Answer 1

store.load的callback里拿不到自定义数据。可以人工发ajax请求拿json ，这样才能自己处理返回结果，然后用store.loadData读入数据

Answer 2

jsonStore.load({
    params: { userid: '111' },
    callback: function(record) {
        //请问此处如何获取username,sex,age的值？？？
        for (var i = 0; i < record.length; i++) {
            alert(record[i].get("username") + "," + record[i].get("sex") + "," + record[i].get("age"));
        }
    }
});

Answer 4

大哥，这样只能获取
loginLogs:{
  [lgoinTime:"2011-2-11 23:19:00",.....],
  [lgoinTime:"2011-2-15 23:19:00",.....],
  [lgoinTime:"2011-2-18 23:19:00",.....]
  }
里面的值！
