javascript - Socket.io broadcast to room not working in socket.io v.0.9.13 - Stack Overflow

socket.broadcast.to(newroom).emit('updatechat', 'SERVER', socket.username+' has joined this room');

is not hitting the client side. I can only see message from:

socket.emit('updateActivity', 'SERVER', 'you have CONNECTED to '+ socketEntity.roomName);

Did I do something wrong with socket.join()?

I also tried to give the broadcast event a different name instead of updateActivity, but it won't work either.

There is no mention in the log output about the broadcast emit at all.

Question Update:

I found a solution that if I replace broadcast.to() to the following snippet, it would work:

socket.get(socketEntity.roomId, function (error, room) {
   io.sockets.in(room).emit('updateActivity', 'SERVER', 'you -joined- this group '+ socketEntity.roomName);
});

But I don't know why that is the case at the moment...so somehow the room parameter for io.sockets.in() above isn't the same as the string socketEntity.roomId?

Original Code:

Server:

io.sockets.on ('connection', function (socket){
    socket.on('joinRoom', function(socketEntity){
        socket.join(socketEntity.roomId);
        socket.emit('updateActivity', 'SERVER', 'you have CONNECTED to '+ socketEntity.roomName);
        socket.broadcast.to(socketEntity.roomId).emit('updateActivity', 'SERVER', 'you -joined- this room'+ socketEntity.roomName);
    });
});

Client:

HTML:

<ul id="activityList" class="dropdown-menu"></ul>

JavaScript:

$(document).ready(function(){
    var socketEntity = {roomId:sampleRmId, roomName: "sample room"}
    socket.emit('joinRoom', socketEntity);


    socket.on('updateActivity', function (username, data){
        $('#activityList').prepend('<li><a href="#"><div>'+ data +'</div></a></li>');
    });
})

socket.broadcast.to(newroom).emit('updatechat', 'SERVER', socket.username+' has joined this room');

socket.emit('updateActivity', 'SERVER', 'you have CONNECTED to '+ socketEntity.roomName);

socket.broadcast will send the message to all the other clients except the client it is being called on.

socket.emit sends to that particular client only

io.sockets.emit sends to all clients

socket.broadcast.to(newroom).emit('updatechat', 'SERVER', socket.username+' has joined this room');
