我正在使用 SignalR jQuery 库与群组发送聊天,但在我的情况下我看不到聊天可以发送这里是代码...
我已经为小组上课并从jQuery传递小组但似乎有些不对劲,我看不到可以通过聊天窗口发送聊天任何人帮助我......
班级:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;
using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Hubs;
namespace Chat.Hubs
{
[HubName("myChatHub")]
public class ChatHub : Hub
{
public void Send(MyMessage message)
{
// Call the addMessage method on all clients
//Clients.All.addNewMessageToPage(message.Msg);
Clients.Group(message.GroupName).addNewMessageToPage("Group Message " + message.Msg);
}
//server
public void Join(string groupName)
{
Groups.Add(Context.ConnectionId, groupName);
}
}
public class MyMessage
{
public string Msg { get; set; }
public string GroupName { get; set; }
}
}
看法:
@{
ViewBag.Title = "Chat";
}
<h2>Chat</h2>
<div class="container">
<input type="text" id="message" />
<input type="button" id="sendmessage" value="Send" />
<input type="hidden" id="displayname" />
<ul id="discussion">
</ul>
</div>

// Get the user name and store it to prepend to messages.

});

//chat.server.send($('#displayname').val(), $('#message').val());
// Clear text box and reset focus for next comment.

});
});
});
// This optional function html-encodes messages for display in the page.
function htmlEncode(value) {
