I’m using the following scripts below to store a list of users who are logged in to the chat I’m doing in socket.io and nodejs, but I wanted to store more than one object, in case I’m only able to store the id,Someone could give me a help on how to solve this problem. Thank you!
- Below js file.
var users = [];
io.on("connection", function(socket){
console.log("User connected: ", socket.id);
socket.on("user_connected", function(username){
socket.username = username;
users[username] = socket.id;
io.sockets.emit("user_connected", Object.keys(users));
});
});- Below index.
function enterName(){
io.emit("user_connected", idUser);
return false;
}
io.on("user_connected", function(users){
$("#lista_usuarios").empty();
$.each(users, function(indice){
opcao_usuario = ""+users[indice]+"<br />";
$("#lista_usuarios").append(opcao_usuario);
});
});
Very confusing your code, in the key username of the array is inserting the id, tbm did not understand why did not use a
objetoinstead of aarraypq will have key and value, in fact if it were I would not create variable any pass the data directly onemit, thus:{id: socket.id, username: socket.username}– LeAndrade
In the case "users = [];" -> are the users who log into the chat with a certain key, then I get the id in the case that is the username and compare with the user to show the list of users. Could you give me a hand tweaking that code?
