Hello everyone, I'm trying to make a 'chat room' for my course project and, above is my code. So when I submit my form nothing happens, I don't get any output. It Seems my entered text didn't go to the server. Please help me solve this issue. Thank you.
Solution
You don't currently have a handler for the form submit in your javascript. Just add this inside document.addEventListener:
$('form#chat').submit(function(event) {
const selection = document.getElementById('text').value;
socket.emit('submit value', {'selection':selection});
return false;
});
