Unfortunately, this is a remarkable stupid question. However, I could not figure out how to make a working click counter für the Bootstrap carousel button. The problem is the span element for the previous and next icons.
The button counter does not count clicks on the repective span element.
$('button').click(function(btn) {
btn.target.dataset.click_counter_hidden = (+btn.target.dataset.click_counter_hidden || 0) + 1;
$('#click_search_left').val($('button[data-id="slider_left"]').attr("data-click_counter_hidden") || 0);
$('#click_search_right').val($('button[data-id="slider_right"]').attr("data-click_counter_hidden") || 0);

Add your counter data attribute to the two buttons (this is just to help initialize).
<button data-click_counter_hidden="0">
Check to see if click event was on button. If not it must've been the child span element so get the parent (the button).
$('button').on('click', function(e){
$t = $(e.target);
if (!$t.is('button')){
$t = $t.parent();
}
clicks = parseInt($t.data('click_counter_hidden')) + 1;
$t.data('click_counter_hidden', clicks);
// display counter value elsewhere if needed
});

I read the Bootstrap documentation about carousel, also tried all available "example" in the search engine. Unfortunately, there is no way I can achieve such an effect.
I try get effect and add name every slider as tab. Can anyone little help me on how to add extra tabs like this? I paste example photo here:
You are right, Bootstrap does not support carousel slider tabs out of the box. But because Bootstrap uses the data attributes data-bs-target and data-bs-slide-to for the indicators you can apply them to other elements.
For example, apply them on a list outside of the carousel, which are the slider tabs:
<ul class="custom-indicators">
<li data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" aria-label="Slide 1">
Slide 1
</li>
...
</ul>
The slider tabs in the snippet has more classes to position everything using a row with four columns col. Simply clicking on a <li> element will already set the carousel to that slide index (0).
To style the active slider tab use JavaScript by toggling a class on it, like .active and style it using CSS.
Here are two basic examples, using Jquery or plain Javascript.
Solution with Jquery
Lucky for us, Bootstrap’s carousel class exposes events for hooking into carousel functionality, like slide.bs.carousel:
$('#carouselExampleIndicators').on('slide.bs.carousel', event => { ... });
This function will fire whenever the carousel transitions to another slide. Inside access the event property to, which holds the index of the next slide. Then toggle the active class:
const nextSlide = event.to;
$('.custom-indicators li').removeClass('active');
$('.custom-indicators li[data-bs-slide-to=' + nextSlide + ']').addClass('active');
Now apply some custom CSS to style the tabs, and that's. Here's the complete basic example of custom indicators that can be styled:
$('#carouselExampleIndicators').on('slide.bs.carousel', event => {
const nextSlide = event.to;
$('.custom-indicators li').removeClass('active');
$('.custom-indicators li[data-bs-slide-to=' + nextSlide + ']').addClass('active');
});
.custom-indicators li {
border-top: 3px solid transparent;
}
.custom-indicators li.active {
color: black;
font-weight: bold;
border-top: 3px solid black;
}

Solution with JavaScript
Here's a solution that uses plain Javascript to accomplish the same thing. It loops over all slider tabs removing the class active and applies it on the slider tab that has the index (data-bs-slide-to="?") of the next slide.
var carousel = document.querySelector('#carouselExampleIndicators');
carousel.addEventListener('slide.bs.carousel', event => {
var nextSlide = event.to;
var customIndicators = document.querySelectorAll('.custom-indicators li');
for (var i = 0; i < customIndicators.length; i++) {
customIndicators[i].classList.remove('active');
}
document.querySelector('.custom-indicators li[data-bs-slide-to="' + nextSlide + '"]').classList.add('active');
});
.custom-indicators li {
border-top: 3px solid transparent;
}
.custom-indicators li.active {
color: black;
font-weight: bold;
border-top: 3px solid black;
}

I'm trying to build a bootstrap carousel to show some product images I get from an API.
I create a div for the first image with the class "active"
Then I loop to add the other images without that class (at the beginning I did the for with all the images but they all get the class active so it didn't work).
I'm pretty sure there should be a more elegant way to do this but i haven't found it yet.
Here is the code:
HTML:
<div class="list-group" id="product-container"> </div>
JS:
function showProduct(){
let product = currentProduct
productContainer.innerHTML = `
<div class="list-group-item">
<h1> ${product.name}</h1>
<hr>
<div class="col">
<div class="container">
<div class="justify-content-between">
<h4 class="mb-1"> Precio </h4>
<p> ${product.currency} ${product.cost}
</div>
<div class="justify-content-between">
<h4 class="mb-1"> Descripción </h4>
<p> ${product.description}
</div>
<div class="justify-content-between">
<h4 class="mb-1"> Categoría </h4>
<p> ${product.category}
</div>
<div class="justify-content-between">
<h4 class="mb-1"> Cantidad de Vendidos </h4>
<p> ${product.soldCount}
</div>
<div class="justify-content-between">
<h4>Imágenes Ilustrativas</h4>

</button>
<button class="carousel-control-next" type="button" data-bs-target="#carouselExampleControls" data-bs-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="visually-hidden">Next</span>
</button>
</div>
</div>
</div>
</div>
</div>`;
appendImages()
};
function appendImages(){
let imagesDiv = document.getElementById("carousel-images");
product = currentProduct;
let HTMLContentToAppend = `
<div class="carousel-item active">
<img src="${product.images[0]}" class="d-block w-100" alt="${product.name}">
</div>`;
for (let i = 1; i<=product.images.length; i++){
HTMLContentToAppend +=`
<div class="carousel-item">
<img src="${product.images[i]}" class="d-block w-100" alt="${product.name}">
</div>
`
}
imagesDiv.innerHTML = HTMLContentToAppend;
} ```
I dont really understand what happens when i press the buttons of the caroussel so i think this problem is related to the unelegant way in which i added the images. Thanks and any comment to optimize my code is wellcome! :)
What JavaScript dependencies needs to be included when I want to use just the Carousel functionality? That means I don't want to use bootstrap.js, just JS necessary for Carousel (carousel.js, ...).
The setup code (with regards to the docs) is:
var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel)
But obviously the Bootstrap 5 part is missing, as I get the error:
(index):511 Uncaught ReferenceError: bootstrap is not defined
I can't seem to find this info in Bootstrap's official docs and anywhere else.
I does not give the error if you include bootstrap bundle for instance.
So you must not have included popper or jquery or bootstrap(.min).js

As I said in the title, I am trying to use JavaScript to update the favicon (shortcut icon) depending on Bootstrap Carousels.
For example, As the carousel changes to the second slide, 2.ico should be the favicon, as the carousel changes to the third slide, 3.ico should be the favicon. Here's what I have done.

You need to add an event listener to your carousel. You have more detail explanation in the docs page. But a simple javascript example for your HTML would be
<script>
$(document).ready(function() {
const myCarousel = document.getElementById('carouselExampleControls')
myCarousel.addEventListener('slid.bs.carousel', function() {
let currentIndex = $('.carousel-item.active').index() + 1;
// do something...
})
});
</script>
I use radio buttons like a pagination for my carousel, which works fine. If I change the slide using the carousel buttons instead of the radio buttons, the state of the radio buttons doesn't change, so the selected button doesn't match the selected slide. How can I fix this?
Here is my template
HTML:
<div class="container">
<div id="carousel" class="carousel slide" data-interval="false" data-ride="carousel">
<div class="carousel-inner" role="listbox">
<div class="item active">
<img class="img-responsive center-block" src="http://www.w3schools.com/bootstrap/img_chania.jpg">
</div>
<div class="item">
<img class="img-responsive center-block" src="http://www.w3schools.com/bootstrap/img_chania2.jpg">
</div>
<div class="item">
<img class="img-responsive center-block" src="http://www.w3schools.com/bootstrap/img_flower.jpg">
</div>
<div class="item">
<img class="img-responsive center-block" src="http://www.w3schools.com/bootstrap/img_flower2.jpg">
</div>
</div>
<a class="left carousel-control" href="#carousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
</div>
<br>
<center>
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary active s1"><input type="radio" name="options" autocomplete="off" checked>1</label>
<label class="btn btn-primary s2"><input type="radio" name="options" autocomplete="off">2</label>
<label class="btn btn-primary s3"><input type="radio" name="options" autocomplete="off">3</label>
<label class="btn btn-primary s4"><input type="radio" name="options" autocomplete="off">4</label>
</div>
</center>
JS:
$(function () {
$(".s1").click(function () {$("#carousel").carousel(0);});
$(".s2").click(function () {$("#carousel").carousel(1);});
$(".s3").click(function () {$("#carousel").carousel(2);});
$(".s4").click(function () {$("#carousel").carousel(3);});
});
If you want to keep it as it is you can add
$('#carousel').on('slide.bs.carousel', function (e) {
var idx = $(e.relatedTarget).index() + 1;
$('.s'+idx).button('toggle');
});
but
$(function () {
$(".s1").click(function () {$("#carousel").carousel(0);});
$(".s2").click(function () {$("#carousel").carousel(1);});
$(".s3").click(function () {$("#carousel").carousel(2);});
$(".s4").click(function () {$("#carousel").carousel(3);});
});
is not that good idea. I would suggest to change it and make it like this
I've solved this problem)
Here is a fixed JS :
$(document).ready(function() {
$('#carousel').on('slide.bs.carousel', function(e) {
var idx = $(e.relatedTarget).index();
$('[data-slide-to=' + idx + ']').button('toggle');
});
});
Here is the working Template
