以下是从Ajax响应中收到的Json Data。

{
    "error": {
        "errorCode": "0001",
        "errorText": "SUCCESS"
    },

                }
            ]
        }
    ]
}

使用以下代码提取事件对象中的信息。但我无法做到。需要指导。

$.ajax({ url:"<%=request.getContextPath()%>/service/showInvitedEvents/21",

         dataType:"json", 
         success: function(jsonData) 
         {
           alert("Inside response success");

           $.each(jsonData.responselist.event,function(i,item)
          $.each(Employees,function(i,item)
           {
             alert('Iteration is' + i);
            var teventName = item.eventName;

            var teventVenue = item.eventVenue;
            var tstartDate = item.startDate;
            var tendDate = item.endDate;
            var tstarend = tstartDate +" - "+ tendDate ;            

            $("#eventTable tbody").append("<tr><td><a id="+teventName+i+" href=<%=request.getContextPath()%>/service/session/1234>"+teventName+"</a></td><td>"+teventVenue+"</td><td>"+tstarend+"</td></tr>");

           });

Answer 1

首先，你不能遍历jsonData.responselist.event。 jsonData.responselist是一个数组，所以要么需要进行双循环，要么你总是知道响应列表中只有一个项目你可以遍历jsonData.responselist [0] .event

对于其余部分，我不确定你为什么要这一行：

$.each(Employees,function(i,item)

看起来像是一个错误，因为它在那里是无效的（语法是错误的，它隐藏了i和来自真实的项目）。

Answer 2

代码中以下行的目的是什么：？

$.each(Employees,function(i,item)

尝试删除它，看看会发生什么。

使用Jquery遍历Json
