哪能通過JSON對象列表

Json Object List. 
------------------------- 
     var params = new Object(); 
     params.Id = personId; 
     params.cls = Class; 

$.ajax({ 
       type: "POST", 
       dataType: "json", 
       data: $.toJSON(params), 
       contentType: "application/json", 
       url: "../OtpWebService.asmx/GetStudentDetails", 

         alert(response.d); 

       } 
      }); 
The out-put, when i do alert(response.d); is given below. 
actually this is an json object returned by a above code from c#. 

      [ 
       {"Name":"Nthal","Class":3,"SubjectName":"English "}, 
       {"Name":"Mishal","Class":4,"SubjectName":"Grammer"}, 
       {"Name":"Sanjeev","Class":3,"SubjectName":"Social"}, 
       {"Name":"Michal","Class":5,"SubjectName":"Gk"}, 
      ]

迭代，如果我嘗試警報（反應）;結果將會是 - > [object] [object]。我如何遍歷這個對象列表中的每個元素，並通過document.write打印..？哪能通過JSON對象列表

這是一個數組。你如何迭代數組？ –

[在JavaScript中循環數組]可能的副本（http://stackoverflow.com/questions/3010840/loop-through-array-in-javascript） –

請在您的問題中查找*並考慮是否易於閱讀。你在那裏使用了很多不正確的標記。只需閱讀格式化提示（「提問」頁面就可以在**編輯區旁邊顯示**）。 –

下面的代碼片段可以幫助：

var dataItem = [ 
    {"Name":"Nthal","Class":3,"SubjectName":"English "}, 
    {"Name":"Mishal","Class":4,"SubjectName":"Grammer"}, 
    {"Name":"Sanjeev","Class":3,"SubjectName":"Social"}, 
    {"Name":"Michal","Class":5,"SubjectName":"Gk"}, 
] 

for(x in dataItem) 
{ 
alert(dataItem[x].Name); 
alert(dataItem[x].Class); 
alert(dataItem[x].SubjectName); 
}
