我怎样才能得到 socket.username ？ (socket.io)

Question

想写个简单的聊天记录一下实战经验

好的，但我无法从房间中获得 socket.nickname 通知 join/leave。（当我试过它的时候，他总是伤心一个'undefined'）。

现在好了，尝试创建房间列表

更新代码：

client.js:

$('#roomForm').submit(function() {
    socket.emit('createRoom', $('#roomName').val());
    $('#roomForm').hide();
    $('#chatForm').show();
    return false;
});

socket.on('message', function(data) {
    newMessage(data);
});

socket.on('showRooms', function(rooms) {
    console.log(rooms);
    for(var i = 0; i < rooms.length; i++) {
        $('#rooms').append($('<li>')
                        .append($('<form id="freeRoom">')
                            .append($('<span id="room">').text(rooms[i] + ' ///'))
                            .append($('<button>').text('connect'))));
    };
});

$('#freeRoom').submit(function() {
    socket.emit('connectToRoom', $('#room').text());
    return false;
});

server.js:

io.on('connection', function(socket) {
    socket.on('sendNickname', function(username) {
        socket.username = username;
        users.push(socket.username);
        socket.emit('showRooms', rooms);
    });

    socket.on('disconnect', function() {
        socket.broadcast.to(socket.room).emit('notice', socket.username + ' has left the room');
        users.splice(users.indexOf(socket.username), 1);
        socket.emit('showRooms', rooms);
    });

    socket.on('message', function(data) {
        socket.broadcast.to(socket.room).emit('message', data);
    });

    socket.on('createRoom', function(room) {
        socket.leave(socket.room);
        socket.room = room;
        rooms.push(socket.room);
        socket.join(socket.room);
        socket.emit('showRooms', rooms);
        console.log('Rooms: ' + rooms);
        socket.broadcast.to(socket.room).emit('notice', socket.username + ' has joined to room');
    });

    socket.on('connectToRoom', function(room) {
        console.log('Will connect to that room: ' + room);
        socket.join(room);
    });
});

**更新 2：** 尝试连接免费创建的房间：

$('#freeRoom').submit(function() {
    socket.emit('connectToRoom', $('#room').text());
    return false;
});

P.S。还有...对不起我的英语 >.<

您发出的事件名称，即 'connect' 与 Socket.io 一起保留在 Socket.io 中=25=]'message' 和 'disconnect':

http://socket.io/docs/#sending-and-receiving-events

Socket.IO allows you to emit and receive custom events. Besides connect, message and disconnect, you can emit custom events:
...

将其更改为其他内容，例如：

Server.js:

io.on('connection', function(socket) {
socket.on('send-nickname', function(nickname) {
    socket.nickname = nickname;
    users.push(socket.nickname);
    console.log(users);
});
...

Client.js

socket.emit('send-nickname', nickname);
