Question

我是signalR中的新手（和JQuery：D）.....我想设置一些用户名并将其映射到connectionId ...在检查了一些样本后这是我的代码。如果它不起作用.. ...页面正在运行而没有错误，但div id =＆＃34; msg＆＃34;保持不变。

现在我想要的是在客户端页面上编写用户名和连接列表。

Answer 1

The problem is the hub name. If you don't set the hub name it'll be generated with the name xZHUB.

So you could do 2 things:

Use the default name:

var con = $.connection.xZHUB;

Or change the hub name

[HubName("XZHUB")]
public class XZHUB : Hub

There are also another things you need to check:

The hubs are not static, so ulist will be recreated in each call. You should consider making it static or change that logic.

The "SUB" button will make a post so it won't work. I replaced it with a normal button:

<button ID="SUB">Submit</button>
