{{{body}}}
<input type="hidden" id="ObjectID" value="{{user._id}}">
</body>
</html>
When I run the apllication and log in with user, in the console in the browser, I see that it gets ObjectId for current User.
Then I make a little code for this ObjectID in the file, where i connect socket.io. There I use '#ObjectID' to find this ObjectID.
// connect Socket.io
$(document).ready(function(){
var socket = io();
// connect client to server
socket.on('connect', function(socket){
console.log('Connected to server');
});
// emit user id
var ObjectID = $('#ObjectID')
socket.emit('ObjectID', ObjectID);
// disconnect from server
socket.on('disconnect', function(socket){
console.log('Disconnected from server');
});
});
After that, I want to create Object ID event in server file "app.js" and I want to see this ObjectId in the console of Node.js.
// socket connection
const server = http.createServer(app);
const io = socketIO(server);
io.on('connection',(socket)=>{
console.log('Connected to client');
// listen to object ID event
socket.on('ObjectIO',(ObjectID)=>{
console.log('User ID is: ', ObjectID);
});
// listen to disconnection
socket.on('disconnect',(socket)=>{
console.log('Disconnected from Client');
});
});
But after run the application and after log in a user, I don't see in the console to print current ObjectID.
Please help me to fix this problem.

You are listening for ObjectIO and you are emitting ObjectID. Change socket.on('ObjectIO',(ObjectID)=>{ to socket.on('ObjectID',(ObjectID)=>{
