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');

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.
I was able to find some workaround: creating one JavaScript file for each HTML page, this is redundant and non-optimal I know, but at least it works.
This also made me realize that the commented-out line was blocking the program because the index.html page doesn't use the previous_page button, that's what led me to make a JS file for each HTML page.
If anybody has any other suggestions I am all ears.
Edit: I reduced the number of JS scripts to only 2. One for the index.html and the other for the identically-structured html pages of the other questions.

I am currently attempting to learn Javascript and starting with a very basic incremental game where you click a button and it increases. I implemented a save button that properly saves to local storage, however upon refresh, it gets reset.
This is the local storage after hitting save, however, it gets reset to 0 when the page is refreshed.
I wanted to implement save functionality in the following way (see loadGame() and saveGame()):
// JavaScript Document
var saveState = {
food: 0
};
var GlobalFood = 0;
window.onunload = saveGame();
window.onload = loadGame();
function loadGame(){
var loadSaveStateString = localStorage.getItem('saveState');
saveState = JSON.parse(loadSaveStateString);
}
function saveGame(){
var saveStateString = JSON.stringify(saveState);
localStorage.setItem('saveState', saveStateString);
}
function tutorialFoodBtnFunc() {
var fVal = document.getElementById("GlobalFood");
GlobalFood++;
fVal.innerHTML = GlobalFood;
saveState['food'] = GlobalFood;
}
function tutorialFoodBtnFunc2() {
var fVal = document.getElementById("GlobalFood");
if(GlobalFood < 1)
{
var foodError = document.getElementById("foodErrorText");
foodError.classList.add("fade-in");
setTimeout(function (){
foodError.classList.remove("fade-in");
}, 2000)
}
else
{
GlobalFood--;
fVal.innerHTML = GlobalFood;
saveState.food = GlobalFood;
}
}
Here's my HTML as well if it's relevant:
<html>
<head>
<meta charset="utf-8">
<title>Wilderness</title>
<link rel="stylesheet" href="styling/tutorial.css">
<script src="js/main.js"></script>
</head>
<div id="page-wrapper">
<body>
<div id="nav">
<p class="GlobalVals">Foodstuffs: </p><span class="GlobalVals" id = "GlobalFood">0</span>
</div>
<div id="tutorialBody">
<button id="tutorialFoodBtn" onclick="tutorialFoodBtnFunc()">Gather Berries</button>
<button id="tutorialFoodBtn2" onclick="tutorialFoodBtnFunc2()">Eat Berries</button>
<p id="foodErrorText">You have no berries!!!</p>
<button id="tutorialFoodBtn2" onclick="saveGame()">Save!!</button>
</div>
</body>
</div>
</html>
First of all, onunload and onload should reference a function. (What you did is execute the function)
window.onunload = saveGame;
window.onload = loadGame;
Then, your code is properly loading the saveState, but you're not assigning it to your GlobalFood variable.
function loadGame(){
var loadSaveStateString = localStorage.getItem('saveState');
saveState = JSON.parse(loadSaveStateString);
GlobalFood = saveState.food;
var fVal = document.getElementById("GlobalFood");
fVal.innerHTML = GlobalFood;
}
As you might know from my previous posts, I am developing a chrome extension. I have a button that toggles the extension on & off, and this button's state is saved when you click out of the extension. You can see the code for this below:
popup.html
<!DOCTYPE html>
<html>
<head>
<link rel="StyleSheet" type="text/css" href="style_popup.css"/>
<script type="text/javascript" src="popup.js"></script>
</head>
<body>
<div class="navbar">
View My Dashboard
</div>
<h1 class="center">[Title]</h1>
<button id="buttonclick" class="button">Enable Control</button>
<br> <img src="green_circle.PNG" height="140" width="150" id="centerimage"> <br>
<p class="center" id="status"> [Title] is running! </p>
</body>
</html>
popup.js
let changeColor = document.getElementById('changeColor');
chrome.storage.sync.get('color', function(data) {
changeColor.style.backgroundColor = data.color;
changeColor.setAttribute('value', data.color);
});
document.addEventListener('DOMContentLoaded', function() {
var link = document.getElementById('buttonclick');
// onClick's logic below:
link.addEventListener('click', function() {
handler();
});
});
function handler()
{
chrome.storage.local.get({count: 0}, function (result) {
var count = result.count;
var buttonState = document.getElementById('buttonclick');
var imageState = document.getElementById('centerimage');
var status = document.getElementById('status');
if (count == 0) {
buttonState.style.backgroundColor = "#75ad0a";
buttonState.innerHTML = "Enabled";
imageState.src = "green_circle.PNG";
status.innerHTML = "[Title] is running!"
count = 1;
}
else {
buttonState.style.backgroundColor = "#AA2B0E";
buttonState.innerHTML = "Disabled";
imageState.src = "red_circle.png";
status.innerHTML = "[Title] is not running!"
count = 0;
}
chrome.storage.local.set({count: count});
});
}
However, I am running into a bit of a pickle. I want to make it such that if a user were to click the button (thereby disabling the extension), exit the chrome extension, and then click back into it, it would still show as disabled. With my current case, however, it will just display the "Enable Control" and "[Title] is running" every time they open the extension UNTIL the user clicks the button. In other words, it would be reset & and I want the state to be preserved. As you can see from my popup.js, I've already written code that saves the state of a variable, but I am unsure how to actually make the state be preserved in the HTML. I would greatly appreciate any help, thanks!
So this code selects random image whenever a person loads my website, how can I change the code so that images are selected sequentially from first to last everytime a person loads the website and then again resets to first image when the counter reaches the end?
P.s- The code works fine on hosting server, here it gives an error i don't know why.
window.onload = choosePic;
var myPix = new Array("https://i.imgur.com/LHtVLbh.jpg", "https://i.imgur.com/2YHazkp.png", "https://i.imgur.com/Uscmgqx.jpg");
function choosePic() {
var randomNum = Math.floor(Math.random() * myPix.length);
document.getElementById("myPicture").src = myPix[randomNum];
}
<!DOCTYPE html>
<html>
<head>
<title>Random Image</title>
<script src="thumb.js"></script>

<body>

</body>
</html>
You can use localstorage to achieve this. When the user enters the website, you can do something like:
var pictureIndex = localstorage.getItem("pictureIndex");
But since it may be the user's first visit, it would be better to have:
var pictureIndex = localstorage.getItem("pictureIndex") || 0;
Then, you just increment the pictureIndex and perform a modulo operation (for the case when this is the last image)
pictureIndex = (pictureIndex + 1) % myPix.length;
To save this index, you can use
localStorage.setItem('pictureIndex', pictureIndex);
Next time when the user refreshes the page (or comes back), he will get the next picture in your array.
The final code should look like this:
window.onload = choosePic;
var myPix = new Array("https://i.imgur.com/LHtVLbh.jpg", "https://i.imgur.com/2YHazkp.png", "https://i.imgur.com/Uscmgqx.jpg");
function choosePic() {
var pictureIndex = window.localStorage.getItem("pictureIndex") || 0;
pictureIndex = (pictureIndex + 1) % myPix.length;
window.localStorage.setItem("pictureIndex", pictureIndex);
document.getElementById("imgid").innerHTML = pictureIndex;
document.getElementById("myPicture").src = myPix[pictureIndex];
}
<!DOCTYPE html>
<html>
<head>
<title>Random Image</title>
<script src="thumb.js"></script>
</head>
<body>
Press "Run" multiple times to cycle through the images.
Currently showing: <span id="imgid"></span>
<img src="images/spacer.gif" id="myPicture" alt="some image">
</body>
</html>
Note that the above code might not work here (but you can test it locally) due to some security restrictions from jsfiddle. A working version can be accessed >here<
function choosePic() {
var local_item = 0;
if(localStorage.getItem('pic_key')){
local_item = parseInt(intvlocalStorage.getItem('pic_key'));
}
if(local_item >= myPix.length){
local_item = 0;
}
localStorage.setItem('pic_key', local_item + 1);
document.getElementById("myPicture").src = myPix[local_item];
}
You can use LocalStorage to achieve this. When the user enters the website, you can store the key and increment it.
Use local storage to save the data you need [e.g. visited = 3(3rd time the same person visited your website)]
Your js code can be implemented like this:
window.onload = choosePic;
var myPix = new Array("https://i.imgur.com/LHtVLbh.jpg", "https://i.imgur.com/2YHazkp.png", "https://i.imgur.com/Uscmgqx.jpg");
function choosePic() {
if (localStorage.getItem('visited') == null)
{
document.getElementById("myPicture").src = myPix[0];
localStorage.setItem('visited', 1);
}
else if (localStorage.getItem('visited') >= myPix.length)
{
localStorage.setItem('visited', 0);
document.getElementById("myPicture").src = myPix[localStorage.getItem('visited')];
}
else
{
document.getElementById("myPicture").src = myPix[localStorage.getItem('visited')];
localStorage.setItem('visited', localStorage.getItem('visited') + 1);
}
}
I'm trying to build something that would resemble a slide show, where you have an image and when you click on it, it is replaced by another randomly in my series of images. I first tried with simple html, but of course the images don't switch randomly. So I did my research and found that it could be done with an array in Javascript. I just don't really know a lot about javascript…
This is what I could find but it doesn't work, I'm sure there is a stupid mistake in there that I can't see:
this is my javascript
function pickimg2() {
var imagenumber = 2 ;
var randomnumber = Math.random();
var rand1 = Math.round((imagenumber-1) * randomnumber) + 1;
myImages1 = new Array();
myImages1[1] = "img_01.gif";
myImages1[2] = "img_02.gif";
myImages1[3] = "img_03.gif";
myImages1[4] = "img_04.gif";
myImages1[5] = "img_05.gif";
myImages1[6] = "img_06.gif";
myImages1[7] = "img_07.gif";
myImages1[8] = "img_08.gif";
myImages1[9] = "img_09.gif";
var image = images[rand1];
document.randimg.src = "myImages1";
}
there is my html
<!DOCTYPE html>
<html>
<head>
<title>mur</title>
<link rel="stylesheet" href="style.css">
<link rel="JavaScript" href="script.js">
</head>
<body onLoad="pickimg2">
<div class="fenetre">
<img src="img_01.gif" name="randimg" border=0>
</div>
</body>
</html>
If someone has another solution I'm open to it!
Fix your script link like RamenChef mentioned:
<script type="text/javascript" src="script.js"></script>
Here's the updated code, check console.log to see the different image urls getting requested.
var myImages1 = new Array();
myImages1.push("img_01.gif");
myImages1.push("img_02.gif");
myImages1.push("img_03.gif");
myImages1.push("img_04.gif");
myImages1.push("img_05.gif");
myImages1.push("img_06.gif");
myImages1.push("img_07.gif");
myImages1.push("img_08.gif");
myImages1.push("img_09.gif");
function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
function pickimg2() {
document.randimg.src = myImages1[getRandomInt(0, myImages1.length - 1)];
}
<div class="fenetre">
<a href="#" onClick="pickimg2();return false;">
<img src="img_01.gif" name="randimg" border=0>
</a>
</div>
this code bellow is working. I hope it's what you were asking for

I have function that opens up a window, and the values from the newly opened window are listed in the opener window.
The 2nd window - has this function:
function AddOtherRefDoc(name, number) {
var remove = "<a href='javascript:void(0);' onclick='removeRefDoctor(this)'>Remove</a>";
var html = "<li><b> Referral Doctor: </b>"+name+"<b>, Referral No: </b>"+number+ " " +remove+" <input type='text' name='ref_docs' value='"+name+"'></input><input type='text' name='ref_nos' value='"+number+"'></input></li>";
opener.jQuery("#r_docs").append(jQuery(html));
}
The function that calls the one above is:
function addRefDoc(){
var count = 0;
var ref_docarray ;
var ref_noarray ;
<%for(int i1=0; i1<vec.size(); i1++) {
prop = (Properties) vec.get(i1);
String ref_no = prop.getProperty("referral_no","");
String ref_name = (prop.getProperty("last_name", "")+ ","+ prop.getProperty("first_name", ""));
%>
if(document.getElementById("refcheckbox_<%=ref_no%>").checked) {
count++;
if ((ref_doctor!=null)&&(ref_doctor!="")&&(ref_docno!=null)&&(ref_docno!="")) {
ref_docarray = ref_doctor.split(";");
ref_noarray = ref_docno.split(";");
if ((containsElem(ref_docarray,"<%=ref_name%>"))||(containsElem(ref_noarray,<%=ref_no%>))) {
alert("Referral doctor " + "<%=ref_name%>" + " already exists");
} else {
AddOtherRefDoc("<%=ref_name%>", <%=ref_no%>);
}
} else {
AddOtherRefDoc("<%=ref_name%>", <%=ref_no%>);
}
}
<%} %>
self.close();
}
function containsElem(array1,elem) {
for (var i=0;i<array1.length;i++) {
if(array1[i]==elem){
return true;
} else{
return false;
}
}
}
When this function is called, it is supposed to carry the 2 input elements "ref_docs" and "ref_nos" into the page that opened this window. But it is not doing so. It lists the elements alright but when I try to use "ref_docs" and "ref_nos" in another Javascript function in the 1st window, I see that "ref_nos" and "ref_docs" are empty.
What am I doing wrong?
function updateRd(){
var ref_docs = jQuery("#updatedelete").find('input[name="ref_docs"]');
var ref_nos = jQuery("#updatedelete").find('input[name="ref_nos"]'); alert(ref_docs.val() + ref_nos.val());
var rdocs = new Array();
var rnos = new Array();
ref_docs.each(function() { rdocs.push($(this).val()); } );
ref_nos.each(function() { rnos.push($(this).val()); } );
$('#r_doctor').val(rdocs.join(";"));
$('#r_doctor_ohip').val(rnos.join(";")); }
–
This function returns an error saying "ref_docs" and "ref_nos" are undefined.
I think it is trying to use the jQuery on the other page to find "#r_docs" on the current page.
Try:
jQuery(opener.document).find("#r_docs").append(html);
UPDATE:
I created index.html:
<!DOCTYPE html>
<html><head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">

<script type="text/javascript" src="http://code.jquery.com/jquery-1.5.2.js"></script>

and child.html:

var remove = "<a href='javascript:void(0);' onclick='removeRefDoctor(this)'>Remove</a>";

}
</script>
</head>
<body>
<input type="button" value="click" onclick="AddOtherRefDoc('name', 42);"/>
</body>
</html>
UPDATE2:
in your update function document.updatedelete has no attributes ref_docs and ref_nos.
try:
jQuery("#updatedelete")
.find('input[name="ref_docs"], input[name="ref_nos"]')
Where your form is
<form id="updatedelete" ... >
Your function that accesses the DOM elements is incorrect. updatedelete is not a property of document, nor will accessing a ref_docs or ref_nos property automatically build a collection of input elements. Since you're using jQuery already, try this:
var ref_docs = $('input[name="ref_docs"]');
var ref_nos = $('input[name="ref_nos"]');
That will give you Array (or at least array-like) objects that will let you access your inputs:
var rdocs = new Array();
var rnos = new Array();
ref_docs.each(function() { rdocs.push($(this).val()); } );
ref_nos.each(function() { rnos.push($(this).val()); } );
$('#r_doctor').val(rdocs.join(";"));
$('#r_doctor_ohip').val(rnos.join(";"));
