How do you stop listening to a socket.io channel?

Question

In socket.io, you can bind to a socket event/channel like this:

<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost');
   socket.on('news', function (data) {
   console.log(data);
   socket.emit('my other event', { my: 'data' });
 });
</script>

But how do you stop listening to the "news" event?

Answer 1

The off function can also be used.

• socket.off('news'); // stops listening to the "news" event
• socket.off('news', myFunction); // useful if you have multiple listeners for the same event
• socket.off(); // stops listening to all events

According to the Socket.io Client Documentation "the socket actually inherits every method of the Emitter class, like hasListeners, once or off (to remove an event listener)."

Emitter documentation:

• Pass event and fn to remove a listener.
• Pass event to remove all listeners on that event.
• Pass nothing to remove all listeners on all events.
