MVC 4 java脚本错误，无法获取属性'Taskhub‘

Question

我尝试在我的索引页面上显示信号r消息。以下是集线器详细信息

 public class TasksHub : Hub
{
    public void NewTaskDetails(int taskid,string taskname,string created,string role)
    {
        Clients.All.addMessage(taskid, taskname, created, role);

    }

}

 my error is : Unhandled exception at line 60, column 9 in http://localhost:45845/
 0x800a138f-JavaScript runtime error:

无法获取未定义或空引用的属性TasksHub

<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery.signalR-1.1.0.js"></script>
<script src="~/signalr/hubs"></script>
<script type="text/javascript">
$(function ()
{

    var THub = $.connection.TasksHub;
    $messages = $("#messages");
    THub.client.send = function (taskid, taskname, created, role) {
        $messages.append("<br /><b>" + taskid + ":</b>" + taskname);
    }

    $.connection.THub.start();
});

Answer 1

使用驼峰外壳

例如，如果类名为MyChatHub

然后，您应该调用

var chat = $.connection.myChatHub;

希望它有助于并确保所有脚本文件都已加载并签入已添加的Global.asax文件

  RouteTable.Routes.MapHubs();
