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.
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:
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);
});
});
<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
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
