Socket.io broadcast.emit 不工作，但它在没有广播的情况下工作

Question

I'm trying to send a message to everyone except the sender.

server.js

  io.on('connection', (socket) => {
   socket.on('typing', (msg) => {
     io.broadcast.emit('typing', msg);
   });
  });

cleint.html

var socket = io();
socket.emit('typing', 'some message');
socket.on('typing', (msg) => {
    $('#myLabel').append(msg);
});

If i remove the broadcast in server to just io.emit then it works, but the sender also sees the message.

Answer 1

instead of

io.broadcast.emit('typing', msg);

try

socket.broadcast.emit('typing', msg);
