Ich möchte einen Node.js Server mit socket.io ausführen, derzeit sendet es das Paket an einen anderen Client im Raum socket.broadcast.to(socket.room).emit('AddPlayer'... Es scheint jedoch, dass die socket.emit( nicht funktioniert und antwortet nicht auf den Inhalt des Clients anfordern Veranstaltung. Kann jemand sehen, wo ich vielleicht falsch liege? Ich habe versucht, das Socket-Objekt durch die Abfragefunktion übergeben, hatte aber keine Wirkung. Dachte, dass der Umfang der Socket-Variablen in Ordnung war.socket.emit funktioniert nicht aber socket.broadcast funktioniert gut. Möglicherweise Umfang Fehler?
io.on('connection', function (socket) { // on on client connection
socket.on('login', function (uname, pword, email) { // on event login
if (uname != "" && pword != "" && email != "" && validateEmail(email)) { // check if username password and email are all valid inputs
Query('SELECT ID FROM Users WHERE Active AND Username="'+uname+'" AND Password="'+pword+'" AND Email="'+email+'";', function(rows, fields){
if (rows.length == 1){ // check if there was a result
socket.id = rows[0].ID
