Pass the Message project problem with setTimeout or setInterval

I'm making beginner javascript pass the message project I'm having a problem with this: If no input is submitted, an alert should show (using the ‘show' class in the CSS file) in the “Last Message Delivered” section and then disappear after 2 second. I don't know setTimeout and setInterval methods really good and how to break them but if someone could help.
const adder = document.getElementById('message-form')
const cont = document.querySelector('.boxer')
const feeder = document.querySelector('.feedback')
let counter = 0;
adder.addEventListener('submit', e => {
e.preventDefault();
let texto = adder.oop.value
if (texto.length) {
html = `
<div class="boxerr">
<h5 class="p-2 alert alert-danger my-3 text-capitalize feedback">please enter a value to pass</h5>
<h4 class="text-capitalize my-3">last message delivered</h4>
<h4 class="message-content text-uppercase">${texto}</h4>
</div>
`
cont.innerHTML += html
adder.reset()
} else {
let timer = setTimeout(() => {
counter++
feeder.classList.toggle('show')
if (counter === 2) {
clearTimeout(timer)
}
}, 100);
}
});
:root {
--lightBlue: #95b8d1;
--mainwhite: #f5f5f5;
--mainBlack: #333333;
}
.max-height {
min-height: 100vh;
}
body {
background: var(--lightBlue);
}
.message-container {
background: var(--mainwhite);
}
.message-content {

</div>
</div>
</div>
</div>

You can do something like this in the else block:
feeder.classList.add("show");
setTimeout(() => feeder.classList.remove("show"), 2000);
This code will add the show class to the .feedback element and after 2000 milliseconds (i.e. 2 seconds as 1000ms = 1s) the show class will be removed from the .feedback element.
Complete Code:
const adder = document.getElementById('message-form')
const cont = document.querySelector('.boxer')
const feeder = document.querySelector('.feedback')
let counter = 0;
adder.addEventListener('submit', e => {
e.preventDefault();
let texto = adder.oop.value
if (texto.length) {
html = `
<div class="boxerr">
<h4 class="text-capitalize my-3">last message delivered</h4>
<h4 class="message-content text-uppercase">${texto}</h4>
</div>
`
cont.innerHTML += html
adder.reset()
} else {
feeder.classList.add("show");
setTimeout(() => feeder.classList.remove("show"), 2000);
}
});

Bootstrap depends on jQuery, and you're already including jQuery in your code.
But if you want to create a modal without Bootstrap and jQuery, you can do so with CSS and JavaScript. Use an event listener to listen for whatever JavaScript event you desire, then show the modal when that event occurs.
Here is a simple example:
// Show the modal when you hover over the red box
trigger.onmouseover = () => {
modal.style.display = "block";
}
// Hide the modal when you click the close button
document.getElementsByClassName("close")[0].onclick = () => {
modal.style.display = "none";
}
// Hide the modal if you click outside of the modal area
window.onclick = (event) => {
if (event.target == modal) {
modal.style.display = "none";
}
}
#trigger {
height: 100px;
width: 100px;
background-color: red;
}
.modal {
display: none; /* Hidden Initially */
position: fixed;
z-index: 1; /* Higher Z-Index To Sit On Top */
left: 0;
top: 0;
width: 100%; /* Full Width */
height: 100%; /* Full Height */
}
/* Modal Content */
.modal-content {
background-color: #fefefe;
margin: 15% auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
/* Close Button */
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}
<div id="modal" class="modal">
<!-- Modal Content -->
<div class="modal-content">
<span class="close">x</span>
<p>Modal content here</p>
</div>
</div>
<div id="trigger">
Move mouse into this box to trigger modal.
</div>

You just need to declare a new modal object, like:
const sonucModal= document.getElementById('sonucModal');
const modalEl = new bootstrap.Modal(sonucModal);
and then call it like this whenever you need to open it:
modalEl.show();
Here is a JSFiddle for reference, the modal opens automatically after 2 seconds.

How to use Cropper.js with images that are already uploaded to my server instead of cropping and then uploading image to correct folder

Hi I'm new to Js so not really sure how to figure this one out. I have a user pictures gallery on my website and I use simple php file upload script to upload pictures for my users. I have a button under each picture to set given image as a profile pic but I'm in need of getting this picture cropped to correct aspect ratio so I tried using Cropper.js. The problem is I can't find a way to pass an image to cropper.js. else than creating an upload form. I've spent days trying to google the way I could use cropperjs without this upload form but can't seem to find a way. It's my first question on stackoverflow any help would be appreciated.

Ajax post request to .NET Core action and getting result not working

I need to implement email sending modal popup and I'm almost done except ajax send request not hit to success or failure
When I click the send button (id:end-email) It successfully hit the .NET Core action and action return status correctly.
But the problem is my ajax call not waiting for the result and automatically closing popup which is not required. I need to show the message instead of closing popup.

This is my action and it's working fine it returns string message
public virtual IActionResult SendInStockRequestEmail(string SelectedPOIds, string Message, string Subject)
{
var inStockIds = new List<int>(Array.ConvertAll(SelectedPOIds.Split(','), Convert.ToInt32));
string message = _inStockPendingShipmentService.SendInStockShipmentRequestEmail(inStockIds, Message, Subject);
return Json(new DataSourceResult { Data = message });
}

The default type of <button> is submit which submits the form data to the server . You can use input button instead :
<input type="button" class="btn btn-primary" id="send-email" value="Send Email" />

Javascript state change reverting

I have a simple jQuery app to display images from Giphy based on an ajax call, and toggle animate/stop them on mouseclick by toggling the src URL and data-state attributes.
I'm also displaying a different set of images based on user input.
I have a bug where it only animates gifs displayed after the first ajax call. It doesn't animate gifs displayed by subsequent calls. console-logging for each condition makes me think that for the latter it changes the state and changes it back, but I can't wrap my head around why.
Screencap: https://screencast.com/t/uZCzH6E6hZ8n

As it stands, ('#gifs-appear-here').on('click', '.topicImage', ...) is executed inside the buttons' onclick handler, causing that delegated click handler to accumulate every time one of the buttons is clicked.
To fix, simply move ('#gifs-appear-here').on('click', '.topicImage', ...) out of the buttons' onclick handler.
Here it is (significantly tidied) :
$('document').ready(function () {
var topics = [
"Ronaldinho",
"Zidan",
"Messi",
"Maradona",
"Pele"
];
function displayTopics() {
for (var i = 0; i < topics.length; i++) {
$('#buttons').append('<div class="btn btn-info get-giphy" data-attribute=' + topics[i] + '>' + topics[i] + '</div>');
}
}
displayTopics();
$('#buttons').on('click', '.get-giphy', function () {
$('#gifs-appear-here').empty();
var queryURL = "https://api.giphy.com/v1/gifs/search?q=" + $(this).data('attribute') + "&api_key=O2X0wRMnWEjylyUypx1F5UVxCz5Jp8kr&limit=10";
$.ajax({
'url': queryURL,
'method': 'GET'
}).then(function (response) {
var results = response.data;
for (var i = 0; i < results.length; i++) {
if (results[i].rating !== "r") {
var gifDiv = $("<div class='item'/>").prependTo("#gifs-appear-here");
$("<img class='topicImage'/>").attr({
'src': results[i].images.fixed_height_still.url
}).data({
'state': 'still',
'images': results[i].images
}).appendTo(gifDiv);
$('<p/>').text("Rating: " + results[i].rating).appendTo(gifDiv);
}
}
});
});
$('#gifs-appear-here').on('click', '.topicImage', function () {
var data = $(this).data();
if (data.state === 'still') {
$(this).attr('src', data.images.fixed_height.url);
data.state = 'animate';
} else {
$(this).attr('src', data.images.fixed_height_still.url);
data.state = 'still';
}
});
