I am working on the tablet's display of a Pepper robot; I have a functional HTML index page comprising a list of questions—each question redirects to its respective HTML when clicked on—, 2 volume buttons and 2 other buttons—one that pops up an instruction image and the other one that closes the index page and gets back to the splash screen, which when clicked upon, reveals the index page. So far everything is working. The issue is that when I click a question—I get redirected to its HTML page, but then I get stuck there, as neither the 2 volume buttons nor the 2 other buttons work;
I made sure to include the following in each HTML page:
<script type="text/javascript" src="/libs/qimessaging/2/qimessaging.js"></script>
<script type="text/javascript" src="faq.js"></script>
I also reused the same JavaScript functions that worked for the index page.
I commented out some line:
btnPrevious.addEventListener('click', goToPreviousPage);
because I noticed it prevented the splash screen from disappearing when clicked on—i.e., the visibility attribute stays on visible instead of switching to hidden thus revealing the index page, but still, the 3 remaining buttons don't work anyway.
Here is my faq.js code:
/* global QiSession */
var serviceName = 'ADFAQ';
var volumeUpEvent = serviceName + '/VolumeUp';
var volumeDownEvent = serviceName + '/VolumeDown';
var volumeData = serviceName + '/Volume';
/* Clickable buttons */
var btnReturn = document.getElementById('return');
var btnHelp = document.getElementById('call_help');
var btnPrevious = document.getElementById('previous_page');
var btnVolUp = document.getElementById('volume-up');
var btnVolDown = document.getElementById('volume-down');
/* Help image and splash screen */
var helper = document.getElementById('helper');
var img = document.getElementById('click_on_me');
var memory;
var volume;
var audioDevice;
QiSession(connected, disconnected);
function connected (s) {
console.log('QiSession connected');
var questions = document.getElementById('questions');
/* Associating buttons to their respective functions */
btnHelp.addEventListener('click', showHelper);
btnReturn.addEventListener('click', closeQuestions);
//btnPrevious.addEventListener('click', goToPreviousPage);
btnVolUp.addEventListener('click', raiseVolume);
btnVolDown.addEventListener('click', lowerVolume);
img.addEventListener('click', loadQuestions);
questions.addEventListener('click', clickOnQuestion);
s.service('ALMemory').then(function (m) {
m.subscriber(serviceName + '/DialogEnded').then(function (subscriber) {
subscriber.signal.connect(hideQuestions);
});
m.subscriber(serviceName + '/Pepper').then(function (subscriber) {
subscriber.signal.connect(displayPepperHTML)
});
m.subscriber(serviceName + '/RaiseVolume').then(function (subscriber) {
subscriber.signal.connect(raiseVolume);
});
m.subscriber(serviceName + '/LowerVolume').then(function (subscriber) {
subscriber.signal.connect(lowerVolume);
});
memory = m;
});
s.service('ALAudioDevice').then(function (a) {
a.getOutputVolume().then(assignVolume);
audioDevice = a
});
}
function disconnected () {
console.log('QiSession disconnected');
}
function assignVolume(value){
volume = value;
}
function raiseVolume (event) {
var changed = 0;
if(volume < 100) {
volume = Math.min(volume + 5, 100);
audioDevice.setOutputVolume(volume);
changed = 1;
}
memory.insertData(volumeData, volume);
memory.raiseEvent(volumeUpEvent, changed);
}
function lowerVolume (event) {
var changed = 0;
if(volume > 30) {
volume = Math.max(volume - 5, 0);
audioDevice.setOutputVolume(volume);
changed = 1;
}
memory.insertData(volumeData, volume);
memory.raiseEvent(volumeDownEvent, changed);
}
function showHelper (event) {
if (btnHelp.innerHTML === '?') {
helper.style.opacity = '1';
helper.style.zIndex = '1';
btnHelp.innerHTML = '←';
} else {
helper.style.opacity = '0';
helper.style.zIndex = '-1';
btnHelp.innerHTML = '?';
}
btnHelp.blur();
}
function loadQuestions (event) {
memory.raiseEvent(serviceName + '/LoadQuestions', 1);
img.style.visibility = 'hidden';
}
function goToPreviousPage () {
window.location.href = "index.html";
}
function displayPepperHTML() {
window.location.href = "pepper.html";
}
function closeQuestions (event) {
if(location.href != "index.html")
{window.location.href = "index.html";}
memory.raiseEvent(serviceName + '/CloseQuestions', 1);
btnReturn.blur();
}
function hideQuestions (data) {
if (data !== 0) {
img.style.visibility = 'visible';
helper.style.opacity = '0';
btnHelp.innerHTML = '?';
}
}
function clickOnQuestion (event) {
memory.raiseEvent(serviceName + '/' + event.target.id, 1);
}
Here is my non-functioning pepper.html code:
<!DOCTYPE html>
<html lang="fr">
<head>

</head>
<body>
<header>
<h1>Bla bla bla</h1>
<span class="buttons">
<button id="previous_page" class="button-help"> ← </button>
<button id="return" class="button-return">X</button>

<ul id="questions">

<div class="volume-part">

<img src="img/speaker.png" alt="Bla bla bla" style="vertical-align: middle;">
<div id="volume-down" class="Click-me">-</div>
</div>
</ul>
<script type="text/javascript" src="/libs/qimessaging/2/qimessaging.js"></script>
<script type="text/javascript" src="faq.js"></script>

Thank you for your help.
I am expecting the pepper.html page to respond to both the volume and ← and X buttons, as the index.html should, since they use the exact same Javascript.
