調用Web服務的.asmx使用AJAX

我已經實現在一個asp.net web應用程序，它允許用戶選擇的東西，併產生一個電子郵件模板彈出的JavaScript。完成所有必填字段後，用戶通過單擊按鈕發送電子郵件。調用Web服務的.asmx使用AJAX

此按鈕調用JavaScript函數，我收集所有喜歡從，到，主題，正文用戶輸入數據，並希望將此數據發送到我創建了一個Web服務將發送郵件。

我不想用郵寄地址，所以我與web服務去了。

的問題是，我不能發送數據：

$.ajax({ 
      type: 'POST', 
      url: "Services/MailService.asmx/SendMail", 
      dataType: "json", 
      contentType: 'application/json; charset=utf-8', 
      data: { 'loginName': "'" + loginName + "'", 'fromAddress': "'" + fromAddress + "'", 'toAddress': "'" + toAddress + "'", 'mailSubject': "'" + mailSubject + "'", 'mailBody': "'" + mailBody + "'"}, 
      success: function() 
      { 
       alert("The email was sent successfully!"); 
      }, 
      error: function(data) 
      { 
       alert("An error occurred while trying to send the email. " + data.responseText); 
      } 
     });

我知道，我在插入數據屬性是錯誤的。我曾嘗試以下，（一次一個）：

data: JSON.stringify({ 'loginName': loginName, 'fromAddress': fromAddress, 'toAddress': toAddress, 'mailSubject': mailSubject, 'mailBody': mailBody }), 
data: { 'loginName': loginName, 'fromAddress': fromAddress, 'toAddress': toAddress, 'mailSubject': mailSubject, 'mailBody': mailBody }, 
data: { loginName: loginName, fromAddress: fromAddress, toAddress: toAddress, mailSubject: mailSubject, mailBody: mailBody }, 
data: "{ 'loginName': '" + loginName + "', 'fromAddress': '" + fromAddress + "', 'toAddress': '" + toAddress + "', 'maliSubject': '" + mailSubject + "', 'mailBody': '" + mailBody + "' }",

所有這些選項給我下面的錯誤：

An error occurred while trying to send the email. {"Message":"Invalid web service call, missing value for parameter: \u0027mailBbody\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

或

An error occurred while trying to send the email. {"Message":"Invalid JSON primitive: loginName.","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject()\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"}

我不明白是什麼我做錯了。

Web服務是這樣的：

[System.Web.Script.Services.ScriptService] 
public class WebService1 : System.Web.Services.WebService 
{ 
    [WebMethod] 
    public void SendMail(string loginName, string fromAddress, string toAddress, string mailSubject, string mailBody) 
    { 
     MailMessage mailMsg = new MailMessage(fromAddress, toAddress); 
     mailMsg.Subject = mailSubject; 
     mailMsg.Body = mailBody; 

     string pathToCreate = "~/Upload/" + loginName + "/"; 
     if (Directory.Exists(Server.MapPath(pathToCreate))) 
     { 
      if (Directory.GetFiles(Server.MapPath(pathToCreate)).Length > 0) 
      { 
       string[] attachedFiles = Directory.GetFiles(Server.MapPath(pathToCreate)); 
       foreach (string a in attachedFiles) 
       { 
        Attachment data = new Attachment(a); 
        mailMsg.Attachments.Add(data); 
       } 
      } 
     } 

     SmtpClient smtp = new SmtpClient(); 
     smtp.Send(mailMsg); 
    } 
}

請與我分享我還能有什麼辦法來解決這個問題。

謝謝！

我能夠通過成功地發送數據：

data: '{loginName:' + JSON.stringify(loginName) + ', fromAddress:' + JSON.stringify(fromAddress) + ', toAddress:' + JSON.stringify(toAddress) + ', mailSubject:' + JSON.stringify(mailSubject) + ', mailBody:' + JSON.stringify(mailBody) + '}',

我不知道這是正確的方式，但它的工作。
