I would like to create an object with a similar data structure if possible. Must I create a new object for every player? Could somebody tell me how?
players
players.name='John'
players.John.age='12'
players.John.adress='London ..'
players.John.telnumber='09876587655'

Sorry I know this is the basic. I just ask one more question an them i will try learn better javascript. I need to pass data stored in "event" to object."event".id (to be like players.John.id instead players.event.id) Sorry for my bad english.
// in app.js
var fs = require('fs');
var socketio = require('socket.io');
Tail = require('tail').Tail;
var express = require('express');
var http = require('http');
var colors = require('colors');
var app = express()
, server = require('http').createServer(app)
, io = socketio.listen(server); // socket needs to listen on http server
server.listen(9099);
app.use(express.static(__dirname + '/public'));
var port = process.env.PORT || 3000;
app.listen(port, function() {
console.log('\r\n');
console.log("Express listening on port " + port +'.'.green);
});
// Routing
//app.use(express.static(__dirname));
// usernames which are currently connected to the chat
//var players = [];
var players = {};
io.sockets.on('connection', function(socket) {
// do all of your socket work in here
console.log('\r\n');
console.log("Connection".green);
var sessionid = socket.id;
console.log(sessionid);
// Success! Now listen to messages to be received
socket.on('message',function(event){
console.log('Received message:',event);
});
socket.on('add user',function(event){
console.log('New User:',event);
// we store the username in the socket session for this client
socket.username = event;
// add the client's username to the global list
players.event = {};
players.event.id = sessionid;
//players.John.foo = "yeah"
//players.John.name = "John"
console.log(players);
socket.emit('login', {});
// echo globally (all clients) that a person has connected
socket.broadcast.emit('user joined', {
username: socket.username
});
});
//socket.emit('start', 'newround');

Depending on visibility requirements you might want to have the first line as
var players;, otherwise you have a valid JS code that creates a single object and initializes its properties. – PM 77-1 Commented Jun 17, 2014 at 18:48 - Possible duplicate? stackoverflow./questions/1114024/… – bloodyKnuckles Commented Jun 17, 2014 at 18:54

Reset to default 5You're looking for a players object, with individual players referenced by name. So:
var players = {};
players['John'] = {
'age' = 12,
'address' = 'London...',
'telnumber' = '09876587655'
};
You can also access "John" as players.John, but that gets tricky if any of the names contain spaces, etc.
Similarly, the player attributes can be accessed either via:
players.John['age'] = 13;
or
players.John.age = 13;
var name = "John";
var players = {};
players[name] = {};
players[name].age = '12';
players[name].address = "address";
players[name].telnumber = "tel";
