Warum umschließt mein JS SignalR Callback mein $ (function() macht es nicht ausgelöst?

Question

Warum wickeln meine SignalR Callback (von .NET C# serverseitigen Hub zu JavaScript Client-Seite) in einem $(document).ready Handler oder über seine Kurzschrift $(function() macht C# Hub -

Server-Seite:

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

Client-seitiges - JavaScript-Hub dieser spezielle Callback (die Handhabung von startdone und getrennt arbeiten, unabhängig davon gewickelt wird oder nicht ...) nicht ausgelöst Proxy + Rückruf:

[...] 

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(); 
} 

Kann nicht wirklich herausfinden, ich im debug-Modus überprüft der Hub ruft die refreshScheduler so alles sollte in Ordnung sein.

[EDIT]
Hinzugefügt einige Protokolle: $.connection.appointmentHub.connection.logging = true;

Aus irgendwelchen Gründen funktioniert es von Chrome zu IE11, aber nicht umgekehrt ... Ich glaube nicht, dass es mit dem Durchsuchen zu tun hat Ich habe versucht, eine andere Registerkarte in IE zu öffnen und auch mit Opera zu verbinden, aber es ist immer noch die erste Instanz von Chrome zu der ersten Instanz IE11, die funktioniert ... die Handler aus dem Ready-Fix ​​dieses Verhalten zu bekommen ... immer noch nicht Ich verstehe wirklich, was vor sich geht.

Answer 1

Sie müssen den Handler registrieren, bevor Sie die Verbindung starten. Die documentation enthält weitere Details.
