Working with WebSockets to connect to the MQTT server

The following lines declare the onConnectSuccess and connect functions within the APP.HomeAutomation.Manager object. The code file for the sample is included in the mqtt_essentials_gaston_hillar_05 folder, in the home_automation.js file:

onConnectSuccess: function(invocationContext) {
onConnectSuccess: function(invocationContext) {
        // Update the status text
        document.getElementById("status").textContent = "Connected with the MQTT Server";
        // Now, subscribe to home/results/leds/1, home/results/leds/2 and
        // home/results/leds/3
        var client = invocationContext.invocationContext.client;
        for (var i = 1; i < 4; i++) {
            client.subscribe("home/results/leds/" + i);
        }
    },

    connect: function() {
        this.client = new Paho.MQTT.Client(this.host, this.port, this.clientId);
        this.client.onConnectionLost = this.onConnectionLost;
        this.client.onMessageArrived...
