解析jsonstore内容

Question

jsonstore加载的数据如下：

"[{"Year":"2014","Total":"5.6","Rank":"6","Share":"6"},
{"Year":"2013","Total":"5.6","Rank":"6","Share":"6"},
{"Year":"2014","Total":"5.6","Rank":"6","Share":"6"},
{"Year":"2013","Total":"5.6","Rank":"6","Share":"6"}]"

我们需要迭代响应：

FeesByProduct_store = new Ext.data.JsonStore({
        root: 'list',
        url: '...............', 
      fields: FeeByProduct,
        listeners: {load: function(store) {
            //create a json object from the response string
            var res = Ext.encode(Ext.pluck(store.data.items, 'data'));
            // if we have a valid json object, then process it
            if(res !== null &&  typeof (res) !==  'undefined'){
                // loop through the data
                Ext.each(res, function(obj){
                    //add the records to the array
                    if (obj != null) {
                    ...
                    }   

                });
             }

        }
    }
    }); 

但是，在迭代时- 'obj‘包含响应的整个值，而不是一次包含每一行。

这里到底做错了什么？

如果您已经成功地加载了存储，那么原来的json就不再有意义了。在商店上有很多方法可以用来检查或操作商店记录。

您的加载侦听器可能如下所示：

load:function() {
    this.each(function(record) {
        // do something with record here, for example
        console.log(record.getData();
    }
}

检查store documentation，查找您可以用来实现所需内容的其他方法。
