jquery.ajax調用一個.aspx網頁方法

我有以下代碼工作在POC沒有變量和硬編碼的一切。在引入變量以準備使用此通道後，它停止工作。可能是，我沒有看到語法錯誤，或者（我不敢說）這個POC無法支持這樣的請求？jquery.ajax調用一個.aspx網頁方法

從我的aspx頁面sendEmail.aspx

 [System.Web.Services.WebMethod] 
       public static string SendMyEmail(string EmailFromAddress, string EmailFromName, string EmailSubject, string EmailBody) 
       { 

        return "data from server: " + Environment.NewLine + 
          "EmailFromAddress = " + EmailFromAddress + Environment.NewLine + 
          "from = " + EmailFromName + Environment.NewLine + 
          "from = " + EmailSubject + Environment.NewLine + 
          "from = " + EmailBody; 

       } 

    <script type = "text/javascript"> 
    function ShowCurrentTime() { 
     alert("hi"); 

     $.ajax({ 
      type: "POST", 
      url: "SendEmail.aspx/SendMyEmail", 
      data: '{EmailFromAddress: "mike", EmailFromName="mike", EmailSubject="email subject here", EmailBody="email body here"}', 
      contentType: "application/json; charset=utf-8", 
      dataType: "json", 
      success: OnSuccess, 
      failure: function (response) { 
       alert(response.d); 
      } 
     }); 
    }

從我的HTML網頁：

<script type = "text/javascript"> 
function ShowCurrentTime() { 
    alert("hi"); 

    $.ajax({ 
     type: "POST", 
     url: "SendEmail.aspx/SendMyEmail", 
     data: '{EmailFromAddress: "mike", EmailFromName="mike", EmailSubject="email subject here", EmailBody="email body here"}', 
     contentType: "application/json; charset=utf-8", 
     dataType: "json", 
     success: OnSuccess, 
     failure: function (response) { 
      alert(response.d); 
     } 
    }); 
} 

function OnSuccess(response) { 
    alert("all good"); 

    alert(response.d); 
} 
</script> 
</head> 
<body style = "font-family:Arial; font-size:10pt"> 
<form id="form1" runat="server"> 
<div> 
Your Name : 
<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox> 
<input id="btnGetTime" type="button" value="Show Current Time" 
    onclick = "ShowCurrentTime()" /> 
</div> 
</form> 
</body> 
</html>

它運作良好，當Web方法有一個嬰兒車（如下圖所示），甚至在json數據中有多個數據點：

[System.Web.Services.WebMethod] 
     public static string SendMyEmail(string EmailFromAddress) 
     { 

      return "good data from server: " + EmailFromAddress; 

     }

嘗試傳入webmethod需要的所有變量。你只是發送EmailFromAddress，嘗試添加其餘的。這個系統最有可能只傳遞1個參數，正在尋找只有該參數的方法。 – Paritosh

no-go，我原本是這樣的：data：'{EmailFromAddress：「mike」，EmailFromName =「mike」，EmailSubject =「email subject here」，EmailBody =「email body here」}'， – kacalapy

你的ajax應該看起來像這樣。刪除'='並替換爲'：'以在數據字段中創建正確的json。

$.ajax({ 
    type: "POST", 
    url: "SendEmail.aspx/SendMyEmail", 
    data: '{EmailFromAddress: "mike", EmailFromName: "mike", EmailSubject: "email subject here", EmailBody: "email body here"}', 
    contentType: "application/json; charset=utf-8", 
    dataType: "json", 
    success: OnSuccess, 
    failure: function (response) { 
     alert(response.d); 
    } 
});
