How do I add a socket.io socket to a room via their socketid?

Question

I'm running a function with this line I pilfered from the internet somewhere:

io.sockets[socketID].join(roomName);

It isn't working properly. Is there any way I can accomplish adding a socket to a room without having reference to the socket object? Or is there any way to get a reference to the socket object from an ID?

Thanks!

在socket.io 1+中，您将使用服务器上的套接字ID，如下所示：

io.sockets.connected[socketID].join(roomName);
