How to add a textarea to the image preview when uploading - javascript

I've been struggling with this problem 3 entire days. Any help would be appreciated!
I have a button 'ADD MY PHOTO' and when clicked, it comes a popup with the option to upload a picture or more. So, when I click 'Select Files' button or I drag & drop a picture or more, it will preview the pictures on the right side.
What I need help with is: when I upload a picture or 2, I want on the right side of every picture to display a textarea where the user can write something (like a caption). Also, after the pictures and captures are displayed I need the option to remove one or all of them. Here is a picture:
Here is the CodePen code: https://codepen.io/anon/pen/VEQMwm
Thanks in advance for help.
Also, here is the code:
// ---------- THIS IS FOR THE POPUP ---------- //
function CustomAlert() {

dialogoverlay.style.display = "block";
dialogoverlay.style.height = windowHeight + "px";
dialogbox.style.display = "block";
}
this.ok = function () {
document.getElementById('dialogbox').style.display = "none";
document.getElementById('dialogoverlay').style.display = "none";

just replace previewFile function with this.
function previewFile(file) {
let reader = new FileReader()
reader.readAsDataURL(file);
reader.onloadend = function() {
var gallleryDiv=document.getElementById('gallery');
var wrapperDiv = document.createElement("div");
let img = document.createElement('img');
img.src = reader.result;
wrapperDiv.className = "wrapperDiv";
wrapperDiv.appendChild(img)
var textbx = document.createElement("textarea");
wrapperDiv.appendChild(textbx);
var btn = document.createElement("button");
var tx = document.createTextNode("X");
btn.onclick = function() {$(this).closest(".wrapperDiv").remove()}
btn.appendChild(tx);
wrapperDiv.appendChild(btn);
gallleryDiv.appendChild(wrapperDiv);
}
}

Serve text instead of images - Trivia javascript game

I have a working code of a 10 questions' trivia game with a timer (html, javascript, css), that serves images from a folder, and has 4 options for answers.
I want to serve text questions instead of images. Can you assist?
I have manipulated severely the css and html code (and a little the js) to make it cleaner and simpler, using ideas from codepen and the internet. However, my javascript skills are very limited.

Just change the <img> tag for a <p> tag and replace the image filenames inside the variable questions for your question text. Then change these 2 lines:
const imageElement = document.getElementById("question-placement");
imageElement.src = `./assets/images/${questions[questionIndex].image}.png`;
for these 2 lines:
const textElement = document.getElementById("question-placement");
textElement.innerHTML = questions[questionIndex].text;
Everything is pretty straightforward.

</div>

The first issue I found is that you have this code:
<p class="text" id="demo"><img id="demo1" src="img5.png" width=30%; height=400px;> </p>
And here you didn't use part with setting id:
var newsArr = ['<img //here is no id// src="img5.png"width = 30%; height=400px;>',
'<img //here is no id// src="img2.png"width = 30%; height=400px; >',
'<img //here is no id// src="img4.png" width = 30%; height=400px;>'];
And when you are clicking on next and prev button, you are removing your id unconsciously, so your thumbchange() function stop working, because it is based on id.

Get selected value from div dropdown

I have a dropdown from which I want to find the selected value.
The dropdown is basically a big blue button which, when pressed, shows different customers:
When an option is clicked, the value changes to the selected customer.
What I want to do is access this value somewhere else in my HTML script.

You to put the below code to save the selected value inside a variable inside the onclick event.
var selected_Value= $('.dropdownid :selected').val();

You can add pointer-events: none to your h3 elements so that any clicks will fall through to the containing parent div behind it, allowing you to get the correct id to show the correct page:
.myBtn h3 {
background-color: green;
line-height: 2;
cursor: pointer;
pointer-events: none;
}
See example below:
var btn = document.querySelectorAll('.myBtn');
var getModal = document.querySelector('.modal');
var getPages = document.querySelectorAll('.page1');
//console.log(getPages);
for (let i = 0; i < btn.length; i++) {
btn[i].addEventListener('click', () => {
hideModal();
getId();
displayPage()
});
}
function hideModal() {
getModal.style.display = "block";
}
function getId() {
//console.log(event.target.id);
}
function hideall() {
for (let i = 0; i < getPages.length; i++) {
getPages[i].style.display = 'none';
}
}
function displayPage() {
hideall();
var btnId = event.target.id;
//console.log(btnId);
if (btnId == "uno") {
getPages[0].style.display = "block";
} else if (btnId == "dos") {
getPages[1].style.display = "block";
} else if (btnId == "tres") {
getPages[2].style.display = "block";
}
//console.log(getPages[0]);
}
window.addEventListener('click', closeIfOutside);

Javascript Slideshow Functions Not Working

I would please like an explanation to why the slideshow is not working. Below I have used an interval to perpetually change the slideshow, if userClick is false. The white and squared buttons (made of divs) are set to call upon two functions; slideRight() or slideLeft() and clicked(). When the buttons are clicked however, the clicked() function does not seem to change the variable, based on the data on top of the page.
<body>
<div class="page-wrapper">
<header>
<div class="headContent">
<h1 class="titleText">Slideshow</h1>
<h2 class="subTitleText">A slideshow made with JavaScript.</h2>
<p>userClick <span id="uc"></span></p>
</div>
<nav>
<ul>
<li>Home</li>
<li>About</li>
<li>Gallery</li>
</ul>
</nav>
</header>
<div class="body-wrapper">
<h1 class="titleText">Slideshow</h1>
<div id="slideshow">
<div id="leftSlide" onclick="leftSlide(); clicked()"></div>
<div id="rightSlide" onclick="rightSlide(); clicked()"></div>

<p>The image is not invoked by a tag, but invoked by the background property using Javascript.</p>

<script language="javascript">
// Slide function
var slide = ["minivan", "lifeinthecity", "sunsetbodyoflove"];
var slideTo = 1;

slideTo = slideTo - 1;

CSS coding below.

.page-wrapper {

Try changing the checking part to:
window.onload = function() {
setInterval(function () {
document.getElementById("uc").innerHTML = userClick;
}, 100);
}
The first argument of setInterval has to be a function (something that can be called), not a generic piece of code.
