なぜ私のJS SignalRコールバックをラップするのですか？

Question

$(document).readyハンドラまたはその略語$(function()でSignalRコールバックを.NET C＃サーバ側ハブからJavaScriptクライアント側にラッピングする理由トリガされていないこの特定のコールバック（startdoneの取り扱いや切断作業に関係なく、彼らのラップやないさ...）：

サーバー側 - C＃のハブ：

public class AppointmentHub : Hub 
{ 
    public void RefreshSchedulers(string ownerConnectionId, string userId) 
    { 
     Clients.User(userId).refreshScheduler(ownerConnectionId); 
    } 
} 

クライアント側 - JavaScriptのハブプロキシ+コールバック：

[...] 

function getSchedulerInstance() { 
    return $('#scheduler').scheduler('instance'); 
} 

$(function() { 

     // If I move this handler below out of the jQuery document ready ($(function()) ... it works... why? 
     $.connection.appointmentHub.client.refreshScheduler = function(ownerConnectionId) { 
      if (getAppointmentHubConnectionId() !== ownerConnectionId) { 
       getSchedulerInstance().repaint(); 
      } 
     }; 

     $.connection.appointmentHub.connection.disconnected(function() { 
      setTimeout(function() { 
       $.connection.appointmentHub.connection.start(); 
       }, 
       500); 
     }); 

     $.connection.appointmentHub.connection.logging = true; 

     $.connection.appointmentHub.connection.start().done(function() { 
     }); 

}); 

function getAppointmentHubConnectionId() { 
    return $.connection.appointmentHub.connection.id; 
} 

function refreshScheduler() { 
    $.connection.appointmentHub.server.refreshSchedulers(getAppointmentHubConnectionId(), '@User.Identity.GetUserId()'); 
} 

[...] 

// Stuff below works 
function onAppointmentDeleted(e) { 
    ui.notify("Appointment deleted.", "success", 600); 
    refreshScheduler(); 
} 

function onAppointmentUpdated(e) { 
    refreshScheduler(); 
} 

function onAppointmentAdded(e) { 
    refreshScheduler(); 
} 

ハブがrefreshSchedulerを呼び出すデバッグモードでチェックしたので、すべてが問題なくなるはずです。

[EDIT]
は、いくつかのログを追加しました：それは動作しますいくつかの理由から$.connection.appointmentHub.connection.logging = true;

をクロムからIE11へ、しかしそれ以外の方法ではない... ブラウズには関係ないと思う私はIEの別のタブを開いてOperaに接続しようとしましたが、Chromeから最初のインスタンスIE11まではまだ最初のインスタンスです...ハンドラを準備中の修正から外して、本当に何が起こっているのか分かりません。

Answer 1

接続を開始する前にハンドラを登録する必要があります。 documentationに詳細が含まれています。
