mqtt - websocket and cloudmqtt, code example not working -

-

is possible work websockets , cloudmqtt? have following code nothing working. first use mqttw31.js paho , in host file define connection details.

src="js/mqttws31.js" type="text/javascript">  src="js/host.js" type="text/javascript">                                                                          var mqtt;  var reconnecttimeout = 2000;  function mqttconnect() {  mqtt = new paho.mqtt.client(                              host,                              port,                              "web_" + parseint(math.random() * 100,                              10));  var options = {       timeout: 3,       usessl: usetls,       cleansession: cleansession,       onsuccess: onconnect,       onfailure: function (message) {         $('#status').val("connection failed: " + message.errormessage + "retrying");         settimeout(mqttconnect, reconnecttimeout);       }  };  mqtt.onconnectionlost = onconnectionlost;  mqtt.onmessagearrived = onmessagearrived;  if (username != null) {      options.username = username;      options.password = password;  }  console.log("host="+ host + ", port=" + port + " tls = " + usetls + " username=" + username + " password=" + password);  mqtt.connect(options);  }  function onconnect() {      $('#status').val('connected ' + host + ':' + port);      // connection succeeded; subscribe our topic      mqtt.subscribe(topic, {qos: 0});      $('#topic').val(topic);      mqtt.publish("/arduino/commando/", "test intel");  }  function onconnectionlost(response) {      settimeout(mqttconnect, reconnecttimeout);      $('#status').val("connection lost: " + responseobject.errormessage + ". reconnecting");  };  function onmessagearrived(message) {      var topic = message.destinationname;      var payload = message.payloadstring;      $('#ws').prepend('<li>' + topic + ' = ' + payload + '</li>');  };  $(document).ready(function() {  mqttconnect();  });
<header>  <h2>mqtt test</h2>  </header>  <div>  subscribed <input type='text' id='topic' disabled />  status: <input type='text' id='status' size="80" disabled />  <ul id='ws' style="font-family: 'courier new', courier, monospace;"></ul>  </div>

in host file:

host = 'm20.cloudmqtt.com'; // hostname or ip address port = 13365; topic = '/arduino/status/';     // topic subscribe usetls = false; username = "test"; password = "test"; cleansession = true;

use port 33365 , set usetls true.
