將值發送給SignalR中的特定用戶

我有4個文本框在用戶按下發送按鈕後同時填充使用SignalR。在一部分，我發送文本框值給所有用戶，這是行得通的。但是，當我嘗試將值發送給特定用戶時，按下按鈕後，所有文本框都會變空。將值發送給SignalR中的特定用戶

這是工作的代碼，發送值給所有用戶：

這是集線器：

public void Send(string loanType, string loanAmount, string interestRates, string payment) 
    { 
     User sender = GetUser(Context.User.Identity.Name); 

     var username = sender.Name; 
     IEnumerable<string> connectionIds = sender.ConnectionIds; 

     //All connected clients. 
     Clients.All.broadcastMessage(loanType, loanAmount, interestRates, payment); 

    }

，這是JS：

$('#sendmessage').click(function (e) { 
      sendPayment(); 
      e.preventDefault(); 
     }); 


     function sendPayment() { 
     var msgValue = $msgTxt.val(); 
     var loanType = $('#txtLoanType').val(); 
     var loanAmount = $('#txtLoanAmount').val(); 
     var interestRates = $('#txtInterestRates').val(); 
     var payment = $('#txtPayment').val(); 

     if (loanType !== null && loanType.length > 0 && loanAmount !== null && loanAmount.length > 0 && interestRates !== null && interestRates.length > 0 
      && payment !== null && payment.length > 0) { 

      if (viewModel.isInPrivateChat()) { 
       $.connection.hub.start(); 
       chatHub.server.send(msgValue, viewModel.privateChatUser(), $('#txtLoanType option:selected').val(), $('#txtLoanAmount').val(), $('#txtInterestRates').val(), $('#txtPayment').val()); 


      } 
      else { 

       // Call the Send method on the hub. 
       chatHub.server.send($('#txtLoanType option:selected').val(), $('#txtLoanAmount').val(), $('#txtInterestRates').val(), $('#txtPayment').val()); 


      } 
     } 



    chatHub.client.broadcastMessage = function (loanType, loanAmount, interestRates, payment) { 
      $('#txtLoanType').val(loanType); 
      $('#txtLoanAmount').val(loanAmount); 
      $('#txtInterestRates').val(interestRates); 
      $('#txtPayment').val(payment); 
    };

但是當我嘗試發送值給特定的用戶它不工作：因爲我debussing C＃代碼工作我的問題是在JS：

這是C＃方法發送的文本框的值到特定的用戶：

public void Send(string message, string to, string loanType, string loanAmount, string interestRates, string payment) 
    { 
     User receiver; 
     if (Users.TryGetValue(to, out receiver)) 
     { 

      User sender = GetUser(Context.User.Identity.Name); 

      IEnumerable<string> allReceivers; 
      lock (receiver.ConnectionIds) 
      { 
       lock (sender.ConnectionIds) 
       { 

        allReceivers = receiver.ConnectionIds.Concat(sender.ConnectionIds); 
       } 
      } 

      foreach (var cid in allReceivers) 
      { 
       Clients.Client(cid).broadcastMessage(new { message = message, isPrivate = true, loanType = loanType, 
        loanAmount = loanAmount, 
        interestRates = interestRates, 
        payment = payment 
       }); 
      } 
     } 
    }

它會調用私有部分JS文件，該文件是：

   if (viewModel.isInPrivateChat()) { 
       $.connection.hub.start(); 
       chatHub.server.send(msgValue, viewModel.privateChatUser(), $('#txtLoanType option:selected').val(), $('#txtLoanAmount').val(), $('#txtInterestRates').val(), $('#txtPayment').val());

函數簽名不匹配。有不同數量的參數，它們必須完全匹配，否則javascript函數將永遠不會被調用，看起來您嘗試在調用broadcastMessage函數時使用send函數的參數。

在JavaScript的用戶，你正在尋找：

function (loanType, loanAmount, interestRates, payment)

但你要發送：

broadcastMessage(new { message = message, isPrivate = true, loanType = loanType, 
       loanAmount = loanAmount, 
       interestRates = interestRates, 
       payment = payment 
      })
