我在框架4.0中使用信号r。当我调用我的集线器类(testhub)它显示未定义。我的jquery代码如下
<head runat="server">
<title></title>
<script src='<%: ResolveClientUrl("Scripts/jquery-1.6.4.js") %>'></script>
<script src='<%: ResolveClientUrl("Scripts/jquery-1.6.4.min.js") %>'></script>
<script src='<%: ResolveClientUrl("Scripts/jquery.signalR-1.0.0-rc1.js") %>'></script>
<script src='<%: ResolveClientUrl("Scripts/jquery.signalR-1.0.0-rc1.min.js") %>'></script>
<script src='<%: ResolveClientUrl("signalr/hubs") %>'></script>
</head>
<body>
<form id="form1" runat="server">
var data = $.connection.tenantHub;
$.connection.hub.logging = true;
console.log(data); //undefine
</script>
</form>
我有global。在
上没有任何错误void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
RouteTable.Routes.MapHubs();
}
我在Hubs文件夹中有hub类,如下所示。
[HubName("tenantHub")]
public class testhub:Hub
{
public void send(string message)
{
Clients.All.addmessage(message);
}
}
我的包如下
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="jQuery" version="1.6.4" targetFramework="net40" />
<package id="Microsoft.AspNet.SignalR" version="1.0.0-rc1" targetFramework="net40" />

最后一个兼容。net Framework 4.0的signalr版本是1.2.2:
你可以尝试通过打开NuGet包管理器控制台并输入:
来更新你的Signalr版本吗?Install-Package Microsoft.AspNet.SignalR.Client -Version 1.2.2
Install-Package Microsoft.AspNet.SignalR -Version 1.2.2
基于jquery 1.6.4 Fwk 4和signalr1的完整聊天示例:http://www.bluelemoncode.com/2013/02/default.aspx
此外,不要解析两次js脚本(根据您的环境只保留最小化或未压缩):
<script src='<%: ResolveClientUrl("Scripts/jquery-1.6.4.min.js") %>'></script>
<script src='<%: ResolveClientUrl("Scripts/jquery.signalR-1.0.0-rc1.min.js") %>'></script>
