I'm new to using Pusher with my Rails app. Everything is working fine and i'm now able to subscribe to channels and receive JSON message.

But i want to make an button where i can unsubscribe from a specific channel.

I have tried this

<button onclick="unsubscribe_channcel('test_channel')">Unsubscribe</button>

<script>
  function unsubscribe_channcel(channelName) {
  var pusher = new Pusher('APP KEY');
  pusher.unsubscribe(channelName);
};
</script>

But it do not work. If i look in the debug console when i press the button all that happens is that it make a new connection and i keep receiving messages from the "test_channel".

You need to unsubscribe to the channel on the same instance of the Pusher object that you subscribed to the channel on e.g.

<button onclick="subscribe_channel('test_channel')">Subscribe</button>
<button onclick="unsubscribe_channel('test_channel')">Unsubscribe</button>

<script src="http://js.pusher./2.2/pusher.min.js"></script>
<script>
  Pusher.log = function(msg){
    console.log(msg);
  };

  var YOUR_APP_KEY = "1afb3f8f61eb29da86df";
  var pusher = new Pusher(YOUR_APP_KEY);

  function subscribe_channel( channelName ) {
    pusher.subscribe( channelName );
  }

  function unsubscribe_channel(channelName) {
    pusher.unsubscribe(channelName);
  }
</script>
