見JSON通過AJAX

Question

返回

請參閱下面的代碼：

<script type="text/javascript" src="Javascript/json2.js"></script> 
    <script type="text/javascript" src="Javascript/jquery-1.11.1.min.js"></script> 
    <script type = "text/javascript"> 
     function GetData() { 
      $.ajax({ 
       type: "POST", 
       url: "JSONExample.aspx/GetPerson", 
      contentType: "application/json; charset=utf-8", 
      dataType: "json", 
      success: OnSuccess(), 
      //async: false, 
      failure: function (response) { 
       alert('there was an error counting possibles') 
      } 
     }); 

     function OnSuccess() { 
      return function (response) { 
       alert(response.d); 
      } 
     } 
     } 
     GetData() 
    </script> 

我相信response.d返回desterilized JSON。我如何看到JSON，以便我可以將它自己殺滅爲.NET對象？

試試這個：

<script type="text/javascript" src="Javascript/json2.js"></script> 
    <script type="text/javascript" src="Javascript/jquery-1.11.1.min.js"></script> 
    <script type = "text/javascript"> 
     function GetData() { 
      $.ajax({ 
       type: "POST", 
       url: "JSONExample.aspx/GetPerson", 
      contentType: "application/json; charset=utf-8", 
      dataType: "json", 
      success: OnSuccess, 
      //async: false, 
      failure: function (response) { 
       alert('there was an error counting possibles') 
      } 
     }); 

     function OnSuccess(data) { 
      alert(data); 
     } 
     GetData() 
    </script> 

此外，您還可以調試與您的Internet瀏覽器（默認爲F12）的developper工具的信息。

嘗試用你替換這個代碼，如果你已經印刷JSON格式的陣列上這個網址JSONExample.aspx/GetPerson

如果您還沒有印在JSON數組，然後下面的代碼將無法正常工作。

<script type = "text/javascript"> 
     function GetData() { 
      $.ajax({ 
       type: "POST", 
       url: "JSONExample.aspx/GetPerson", 
      contentType: "application/json; charset=utf-8", 
      dataType: "json", 
      success: OnSuccess(response), 
      //async: false, 
      failure: function (response) { 
       alert('there was an error counting possibles') 
      } 
     }); 

     function OnSuccess(response) { 
      return function (response) { 
      var data = JSON.parse(response); 
       console.log(data); 
      } 
     } 
     } 
     GetData() 
    </script> 

您將能夠在開發人員工具的控制檯中看到響應。
