Javascript Node.js Socket.io-如何将消息发送到侦听器中的特定房间？

我试图将消息发送到特定的房间，一旦客户机触发了“joinedRoom”侦听器，如果我将代码放在joinedRoom侦听器之外，代码就可以正常工作，否则它什么也不做

代码：

app.get('/room/:room/user/:user', function(req, res){
    var room = {
        username: req.params.user,
        roomname: req.params.room
    };
    res.render('room', room);
});

var users  = {};

io.sockets.on('connection', function (socket) {
    socket.on('joinedRoom', function(roomData){
        socket.username = roomData.username;
        socket.room = roomData.roomname;

        console.log("Roomname: " + socket.room);
        console.log("Username: " + socket.username);

        socket.join(socket.room);
        socket.broadcast.to(socket.room).emit('newUser', socket.username);

        socket.on('disconnect', function(){
            socket.broadcast.emit('userLeft', socket.username);
            socket.leave(socket.room);

            console.log('Connection id: ' + socket.id);
        });
    });
});

客户端代码：

var socket, roomname, ioRoom;
var socket = io.connect('http://localhost:3000');

socket.on('enterRoom', function(roomname){
    console.log("ENTERED ROOM: " + roomname);
});

socket.on('newUser', function(username){
    pushUserName(username);
    pushUserStatus(username, ' has joined the room <br/>')
});

socket.on('newRoom', function(data){
    alert(data)
});

socket.on('userLeft', function(username){
    pushUserStatus(username, ' has left the room <br/>')
})

function pushUserName(username){
    var el = document.getElementById("username");
    el.innerHTML += username + '<br/>';
}

function pushUserStatus(username, message){
    var el = document.getElementById("joined");
    el.innerHTML += username + message;
}

你在哪里调用客户端上的

joinedRoom

？Hello@MathewJibin我编辑了我的答案，好的是我能够看到joinedRoom是用正确的数据发送和接收的，所以我认为这不是问题=\而且，你的问题是服务器中没有调用处理程序，对吗？或者只是到特定房间的消息没有被调用g从处理程序发送，其他事情包括

console.log

调用是否正常工作？1-问题是，只有当我将发射器置于“joinedRoom”侦听器之外时，消息才会发送2-我能够看到所有console.log正常工作。

doctype html
head
    title Sala #{roomname}

    script(src="https://cdn.socket.io/socket.io-1.4.5.js")
    script(type="text/javascript").
        var socket = io.connect('http://localhost:3000');
        var roomData = {
            roomname: '#{roomname}',
            username: '#{username}'
        }
        socket.emit('joinedRoom', roomData);

    script(src="../../../js/room.js")

  body
      p#joined

      h2 Your nickname: #{username}
