javascript - 无法解析 json 响应，它实际上不为空但返回未定义

Question

我有这个 json 代码，我用它来发送 post 请求并检索数据，然后解析它(请参阅下文)。

$.ajax({
       url: '/test',
       type: 'post',
       data: { id : "1"},
       dataType: 'json',
       success: function(response){
           if(response.success){
               console.log(JSON.stringify(response.disputeRecord));
                $.each(response.disputeRecord, function(index, value){
                   alert(value.creation_date);

                });
           }
       }
    });

这是“response.disputeRecord”的 json 内容(来自控制台的 View )

{"no":7,"employee_id":"MMMFLB003","creation_date":"2015-07-09","log_date":"2015-06-25","log_type":"LOGGED","dispute_time":"07:00","reason":"No Logout data","effect":"Update Logout Data","status":"HR APPROVED","authorized_person":"MMMFLB003","authorized_reason":"You have it","mngmt_updated_at":"2015-07-09 03:12:12","hr_approver":"MMMFLB003","hr_approver_reason":"Approve Dispute Request","hr_updated_at":"2015-07-09 03:13:01"}

如您所见，我试图提醒 json 响应中实际存在的“creation_date”，但它给了我“未定义”，有什么想法、线索吗？

上面的示例显示您没有得到一组 disputeRecord - 只有一个。在这种情况下，each() 会使问题变得困惑，因为没有什么可解析的。试试这个...

$.ajax({
   url: '/test',
   type: 'post',
   data: { id : "1"},
   dataType: 'json',
   success: function(response){
       if(response.success){
           console.log(JSON.stringify(response.disputeRecord));
           console.log(response.disputeRecord.creation_date);
       }
   }
});
