我现在有这段代码设置了缺口和余地:
io.sockets.on('connection', function(client){ var Room = ""; client.on("setNickAndRoom", function(nick, fn){ client.join(nick.room); Room = nick.room; client.broadcast.to(Room).emit('count', "Connected:" + " " + count); fn({msg :"Connected:" + " " + count}); });
我想知道我如何才能有多少人连接到特定的聊天室…例如Room.length
客户端 :
function Chat(){ this.socket = null; this.Nickname = ""; this.Room = ""; var synched = $('#syncUp'); this.Connect = function(nick, room){ socket = io.connect('http://vybeing.com:8080'); Nickname = nick; Room = room; //conectarse socket.on('connect',function (data) { socket.emit('setNickAndRoom', {nick: nick, room: room}, function(response){ $("#connection").html("<p>" + response.msg + "</p>"); }); }); }
我发现了这一点,但给出了未定义的内容:
count = io.rooms[Room].length;
如果您使用的版本<1,
var clients = io.sockets.clients(nick.room); // all users from room
