    <script type="text/javascript" src="Scripts/jquery.signalR-0.5.3.min.js"> </script>

<body>
    <form id="form1" runat="server">
    <div>
    <h2>SignalR</h2>
<input type="text" id="msg"/>
<input type="button" id="broadcast" value="Send" />
        <br />
        <br />
<ul id="messages"></ul>
    </div>
    </form>
</body>
</html>

C#

chat.cs
-------
<pre lang="cs">using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Routing;
using Microsoft.AspNet.SignalR.Hubs;
using Microsoft.AspNet.SignalR;
using Microsoft.SqlServer.Server;
using System.Data.SqlClient;

/// &lt;summary&gt;
/// Summary description for chat
/// &lt;/summary&gt;

public class chat:Hub

{

    public void send (string message)
    {

        Clients.All.addMessgae(message);

    }</pre>

i corrected it answer 1 as val('') to val() again i getting same errors as follows

"JavaScript runtime error: Unable to get property 'client' of undefined or null reference"

"JavaScript runtime error: SignalR: Error loading hubs. Ensure your hubs reference is correct, e.g. <script src='/signalr/js'></script>."

"{throw new Error("SignalR: Error loading hubs. Ensure your hubs reference is correct, e.g. <script src='/signalr/js'></script>.");"

suggest me the solution or example

Solution 1

Hi,

You are sending a blank message so your are getting a blank message.

// Your Code
$('#msg').val('')

Should be

$('#msg').val()
