无法通过Ajax到达PageMethod

Question

我正在进行在线测验项目。用户将选择多个问题，在Page_Load方法中从db中随机抽取问题和选择。用户将别致标记。然后当用户点击提交按钮时，用户的选择将通过AJAX发送到静态页面方法。尽管有一天的工作，但我是一名初学者，无法将带有Ajax的数据发送给PageMethod。我需要你的帮助。这里是我的代码：

<div id="selections"> 
         <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
         <asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
          <ContentTemplate> 
           <input type="radio" name="secenekler" value="1" id="input1" /> 
           <label class="row qaelement labelClick" for="input1"> 
            <asp:Label ID="TextSecenekA" CssClass="textsecenek" runat="server"></asp:Label> 
           </label> 

           <input type="radio" name="secenekler" value="2" id="input2" /> 
           <label class="row qaelement labelClick" for="input2"> 
            <asp:Label ID="TextSecenekB" CssClass="textsecenek" runat="server"></asp:Label> 
           </label> 

           <input type="radio" name="secenekler" value="3" id="input3" /> 
           <label class="row qaelement labelClick" for="input3"> 
            <asp:Label ID="TextSecenekC" CssClass="textsecenek" runat="server"></asp:Label> 
           </label> 

           <input type="radio" name="secenekler" value="4" id="input4" /> 
           <label class="row qaelement labelClick" for="input4"> 
            <asp:Label ID="TextSecenekD" CssClass="textsecenek" runat="server"></asp:Label> 
           </label> 

           <div class="row"> 
            <asp:Button ID="SoruGonder" ClientIDMode="Static" class="btn btn-primary btn-lg offset-md-4 col-md-4" runat="server" Text="My Last Decision!" /> 
           </div> 
          </ContentTemplate> 
         </asp:UpdatePanel> 
</div> 

JS：

<script type="text/javascript"> 
    function getRadioValue(theRadioGroup) { 
     var elements = document.getElementsByName(theRadioGroup); 
     for (var i = 0, l = elements.length; i < l; i++) { 
      if (elements[i].checked) { 
       return elements[i].value; 
      } 
     } 
     return null; 
    } 

    $(document).ready(function() { 

     $('#SoruGonder').click(function() { 
      var ChoosenChicValue = getRadioValue('secenekler'); 
      if (ChoosenChicValue == null) { 
       alert("Please Make A Choice"); 
      } 
      else { 
       $.ajax({ 
        type: 'POST', 
        url: '/quiz.aspx/quizpagemethod', 
        data: ChoosenChicValue, 
        contentType: 'application/json; charset=utf-8', 
        datatype: 'json', 
        success: function (data) { 
         document.getElementById('<%= TextSoru.ClientID %>').value = data.question; 
         document.getElementById('<%= TextSecenekA.ClientID %>').value = data.selection1; 
         document.getElementById('<%= TextSecenekB.ClientID %>').value = data.selection2; 
         document.getElementById('<%= TextSecenekC.ClientID %>').value = data.selection3; 
         document.getElementById('<%= TextSecenekD.ClientID %>').value = data.selection4; 
        }, 
        error: function() { 
         alert("Ajax Error"); 
        } 
       }); 
      } 
     }); 
    }); 
</script> 






    public class SoruCevapClass 
    { 
     public string question { get; set; } 
     public string selection1 { get; set; } 
     public string selection2 { get; set; } 
     public string selection3 { get; set; } 
     public string selection4 { get; set; } 
    } 

    [System.Web.Services.WebMethod(EnableSession = true)] 
    protected static string GreetingBtn_Click(string PostedAnswer) 
    { 
     System.Diagnostics.Debug.WriteLine("POSTED ANSWER : "+PostedAnswer); //This is not printing on output. 
//... 
    }

在您的ScriptManager补充一点：=的EnablePageMethods “真”
