How to show individual ALT tag and URL in responsive popup image gallery

I am pretty new here and also with Javascript but I have tried for quite some time now and can't get my head around how to have individual data in a popup image gallery.
I have tried adding it in multiple ways, and I do not really need a number (1-..) but an individual URL, also an individual description (using the alt tag). So this is the first code that offered it to me and I hope there is some geeks in this community that can give me an easy and quick "fix".
Many thanks in advance!
Here is some code to make you understand better (hopefully):
HTML:
<div class="popup">
<!-- top bar -->
<div class="top-bar">
<p class="image-name">img1.png</p>
<p class="image-description">Just an image</p>
<span class="close-btn"></span>
!-- image -->
<img src="./img/ads/1.png" class="large-image" alt="Just an image">
<!-- image-index -->
<p class="index">01</p>
</div>
<div class="gallery">
<div class="gallery-image">
<img src="./img/ads/1.png" alt="Just an image" class="image">
</div>...
CSS:
.popup {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%) scale(0);
width: 80%;
max-width: 100%;

max-height: 70%;
border-radius: 20px;
background: rgba(0, 0, 0, 0.75);
display: flex;
justify-content: center;
align-items: center;
z-index: 5;
overflow: hidden;
transition: 1s;
opacity: 0;
}
.popup.active {
transform: translate(-50%, -50%) scale(1);
opacity: 1;
}
.popup.active .close-btn,
.popup.active .image-name,
.popup.active .index,
.popup.active .image-description,
.popup.active .large-image,
.popup.active .arrow-btn {
opacity: 1;
transition: opacity .5s;
transition-delay: 1s;
}
.top-bar {
position: absolute;
top: 0;

}
.image-name {

}
.close-btn {

top: 15px;
right: 20px;
width: 20px;
height: 20px;
border-radius: 50%;
background: #f00;

}
JAVASCRIPT:

const rightArrow = document.querySelector('.right-arrow');
let index = 0; // will track our current image;
images.forEach((item, i) => {
item.addEventListener('click', () => {
updateImage(i);
popup.classList.toggle('active');
});
});
const updateImage = i => {
let path = `./img/ads/${i + 1}.png`;
largeImage.src = path;
imageName.innerHTML = path;
imageIndex.innerHTML = `0${i + 1}`;
index = i;
};
closeBtn.addEventListener('click', () => {
popup.classList.toggle('active');
});
leftArrow.addEventListener('click', () => {
if (index > 0) {
updateImage(index - 1);
}
});
rightArrow.addEventListener('click', () => {
if (index < images.length - 1) { updateImage(index + 1); } });```

Trying to apply a script that should enable a floating button to appear after scrolling a certain amount of px, but it is not working

<script>
document.addEventListener
('DOMContentLoaded',
function() {
jQuery(function($){
$(document).scroll(function()
{
var y = $(this).scrollTop();
if (y > 1810 && $(window
).scrollTop() + $(window
).height() < $(document
).height() - 100) {
$('#addcartsection').addClass
('viewaddcart')
} else {
$('#addcartsection'
).removeClass
('viewaddcart')
}
});
$('#addcartbutton').click
(function(){
$('.single_add_to_cart_button'
).click();
$('html, body').animate({
scrollTop: $('.product_title'
).offset().top
}, 'slow');
});
});
});
</script>
<style>
#addcartsection{
position: fixed;
bottom: 0;
width: 100vw;
z-index: 98;
-webkit-transition: transform
0.34s ease;
transition : transform 0.34s
ease;
transform: translateY(0px); /*adjust this value to the height of your addcartsection*/
}
.viewaddcart{
transform: translateY(0px
)!important;
}
</style>
applied this in a page builder html element but the button is appearing always instead of after scrolling a certain amount of px down the page. are there any errors in the script? sorry i am not an expert at coding.

Seems to be working, make sure you are hiding it by default and display only when viewaddcart class exists on the same button:
#addcartsection {
...
display: none;
}
#addcartsection.viewaddcart {
display: block;
}
document.addEventListener('DOMContentLoaded',
function() {
jQuery(function($) {
$(document).scroll(function() {
var y = $(this).scrollTop();
if (y > 1810 && $(window).scrollTop() + $(window).height() < $(document).height() - 100) {
$('#addcartsection').addClass('viewaddcart')
} else {
$('#addcartsection').removeClass('viewaddcart')
}
});
$('#addcartbutton').click(function() {
$('.single_add_to_cart_button').click();
$('html, body').animate({
scrollTop: $('.product_title').offset().top
}, 'slow');
});
});
});
#addcartsection {
position: fixed;
bottom: 0;
width: 100vw;
z-index: 98;
-webkit-transition: transform 0.34s ease;
transition: transform 0.34s ease;
transform: translateY(0px);
/*adjust this value to the height of your addcartsection*/
}
.viewaddcart {
transform: translateY(0px)!important;
}
.veryHugeDocument {
background: grey;
height: 5000px;
}
#addcartsection {
width: 100px;
color: white;
background: blue;
right: 0;
display: none;
}
#addcartsection.viewaddcart {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="veryHugeDocument">
<h1>My document!</h1>
</div>
<button id="addcartsection">Add to cart!</button>

Delay random position jQuery

I have some code that displays 4 divs at a random hight at specified distances from the viewport sides, each div appears with a different delay speed and then moves around the page at random.
I want to add a delay to the movement of each div so they don't all start and stop moving at the same time but every time I add ad .delay() it breaks. Any help?
Thanks

Pure JS + CSS Slideshow with z-Index: Glitch on last Slide

I try to build a Slideshow in JS + CSS and it works pretty well except one visual glitch. The Transition to the last slides seems somehow broken.
But I couldn't figure out what the problem is. If I comment out the "offset" transition on the last slide, the error doesn't occure.
This is the codeine I am talking about: https://codepen.io/marianbreitmeyer/pen/paeYgZ
The Block of code I mentioned is this one:
const showNext = function() {
clicked = true;
for (i = 0; i <= slides.length-1; i++) {
if( parseInt(slides[i].style.zIndex) === slides.length) {
console.log(slides[i].innerHTML);
triggerAnimation(slides[i], 'offcanvas');
} else if (parseInt(slides[i].style.zIndex) === slides.length-1) {
//the line below triggers the problem
triggerAnimation(slides[i], 'offset');
}
}
};
Maybe someone with more experience could help me :)

Your code might be more simple:
const btn = document.getElementsByClassName('arrow')[0];
const slides = document.getElementsByClassName('slide');
slides[slides.length - 1].classList.add('offset', 'next');
btn.addEventListener("click", function(e) {
var o, n;
for (var i = 0; i < slides.length; i++) {
if (slides[i].classList.contains('offset')) {
slides[i].classList.remove('offset', 'next')
slides[i].classList.add('offcanvas');
o = (slides[i - 1] || slides[slides.length - 1]);
n = (slides[i - 2] || slides[slides.length + i - 2]);
}
if (slides[i].offsetLeft < -slides[i].offsetWidth) {
slides[i].classList.remove('offcanvas', 'next');
}
}
o.classList.add('offset');
n.classList.add('next');
}, false);

animate to right on scroll down and animate back to the left on scroll up

I'm trying to do an animation on page scroll where selected element will animate from left to right on scroll down and if back to top then animate the selected element from right to left (default position), here's what I tried
$(document).ready(function() {
$(window).scroll(function() {
var wS = $(this).scrollTop();
if (wS <= 10) {
$("#test-box").animate({
'left': 100
}, 500);
}
if (wS > 11) {
$("#test-box").animate({
'left': $('#main-container').width() - 100
}, 500);
}
});
});
#main-container {
width: 100%;
overflow: auto;
height: 500px;
}
#test-box {
background: red;
color: #ffffff;
padding: 15px;
font-size: 18px;
position: fixed;
left: 100;
top: 10;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main-container">
<div id="test-box">test</div>
</div>
As you can see, on scroll down, the test box moves as I instruct but when scroll up, it does not go to the left as default, any ideas, help please?

You can add a global variable to control the animation. See the working snippet below please, where I've commented parts of the code that I added:
$(document).ready(function() {
var animated = false; //added variable to control the animation
$(window).scroll(function() {
var wS = $(this).scrollTop();
if (animated && wS <= 10) {
$("#test-box").animate({
'left': 100
}, 500);
animated = false; //animation ended
}
if (!animated && wS > 11) {
$("#test-box").animate({
'left': $('#main-container').width() - 100
}, 500);
animated = true; //it was animated
}
});
});
#main-container {
width: 100%;
overflow: auto;
height: 500px;
}
#test-box {
background: red;
color: #ffffff;
padding: 15px;
font-size: 18px;
position: fixed;
left: 100px;
top: 10;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main-container">
<div id="test-box">test</div>
</div>

This should work, it also uses css for the animation.
$(document).ready(function() {
var box = document.querySelector('#test-box');
var stateClass = '-right';
window.addEventListener('scroll', function(event) {
box.classList.toggle(stateClass, document.body.scrollTop > 10);
});
});
#main-container {
width: 100%;
overflow: auto;
height: 2000px;
}
#test-box {
background: red;
color: #ffffff;
padding: 15px;
font-size: 18px;
position: fixed;
left: 100px;
top: 10;
transition: .5s linear;
}
#test-box.-right {
left: 100%;
transform: translateX(-100%) translateX(-100px)
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main-container">
<div id="test-box">test</div>
</div>
