myCarousels.each(function( index, element ) {
var myCarousel = $("#"+$(element).attr('id'));
myCarousel.append("<ol class='carousel-indicators'></ol>");
var indicators = $("#"+$(element).attr('id') + " .carousel-indicators");
$("#"+$(element).attr('id') +" .carousel-inner").children(".item").each(function(index) {
(index === 0) ?
indicators.append("<li data-target='#"+$(element).attr('id')+"' data-slide-to='"+index+"' class='active'></li>") :
indicators.append("<li data-target='#"+$(element).attr('id')+"' data-slide-to='"+index+"'></li>");

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'm making a carousel slide with Bootstrap carousel. I want to stop auto-playing of slides and I would like to make a button, which controls to toggle the auto-playing on/off.
I've searched about it already and it recommended me to add an attribute data-interval=false for the carousel div or to add a script: $('.carousel').carousel({ interval: false, }).
It stops auto-playing when the above values are set as default value but when I want to toggle the auto-playing on/off, it doesn't work and keeps auto-playing.
Here's the script I have so far:
var total = $('.carousel-item').length;
var currentIndex = $('div.active').index() + 1;
$('.current_slide').html(currentIndex + ' / ' + total);
$('.carousel').on('slid.bs.carousel', function() {
currentIndex = $('div.active').index() + 1;
var text = currentIndex + ' / ' + total;
$('.current_slide').html(text);
});
function navAutoplay() {
if ($('.if_paused').hasClass('carousel_now')) {
$('*.carousel_now').removeClass('carousel_now');
$('.if_started').addClass('carousel_now');
}
else {
$('*.carousel_now').removeClass('carousel_now');
$('.if_paused').addClass('carousel_now');
}
}
$(document).ready(function() {
if ($('.if_started').hasClass('carousel_now')) {
$('.carousel').carousel({
interval: 7000
});
}
else {
$('.carousel').carousel({
interval: false
});
}
})
The html code:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Hi according to docs you should be able to toggle carusel using those methods:
.carousel('cycle')
// to enable cycling
.carousel('pause')
// to stop cycling thru items
I think if you call .carusel() with options object it initilizes it again and may not work as you expect
You just have to read the docs from bootstrap, it's documented there.
Here's an example on how you would implement it.
function navAutoplay() {
const isAutoPlayEnabled = $('#toggle-auto-play').text() === 'Pause';
if (isAutoPlayEnabled) {
// Pause carousel if autoplay is enabled
$('#carouselExampleIndicators').carousel('pause');
$('#toggle-auto-play').text('Auto Play');
} else {
// Enable Auto Play if it's paused
$('#carouselExampleIndicators').carousel({
interval: 500, // Your choice of interval
});
$('#toggle-auto-play').text('Pause');
}
}

I've already tried .carousel('pause'); and .carousel('cycle'); to toggle the auto-playing, and it didn't work.
function navAutoplay() {
if ($('.if_paused').hasClass('carousel_now')) {
$('*.carousel_now').removeClass('carousel_now');
$('.if_started').addClass('carousel_now');
$('.carousel').carousel('cycle');
}
else {
$('*.carousel_now').removeClass('carousel_now');
$('.if_paused').addClass('carousel_now');
$('.carousel').carousel('pause');
}
}
I did manage to get the previous image in the carousel on click but I'm not able to specify the "data-slide-to" image
This is the code for getting the previous image on click
$("#header").carousel('prev');
but while implementing the second one I'm getting no response
$("#header").carousel($(this).data('slide-to',0));
function gotoSlide(number){
$(".carousel").carousel(number);
}

An example using Bootstrap 4's Carousel methods
carousel.on('slide.bs.carousel', function (event) {
var active = $(event.target).find('.carousel-inner > .item.active');
var from = active.index();
var next = $(event.relatedTarget);
var to = next.index();
var direction = event.direction;
});
I need to create a slide when the image is first the left arrow should be hide and when the last image is active right arrow should be hide. I had added my code here. Is there any other alternative method to replace or any new method. Is there any option to modify the code, Can anyone point me in the right direction?
$("[id^=viewDocs]").on("click", function () {
var docId = $(this).attr("id");
var docIndex = docId.substr(docId.length - 1);
var activeItemId = $(this).data("value");
$("div>div.item").removeClass("active");
$("#"+activeItemId).addClass("active");
var appName = $('#SavepatientResultsDetails_appName').val();
var paramValue = $(this).data("id");
$("#myModal").removeClass("hidden");
$('#downloadDocId').attr('href',appName+'/apps/PatientDetailsDoctor/ViewPatientTestResults/downloadUploadDocs?testResultsDocsId='+paramValue);
var modal = document.getElementById("myModal");
modal.style.display = "block";
});

You can use these JavaScript codes.
First:
$('.left').hide();
$('#carousel-example-generic').on('slid.bs.carousel', function (ev) {
var carouselData = $(this).data('bs.carousel');
var currentIndex = carouselData.getActiveIndex();
if (currentIndex >= 1) {
$('.left').show();
}
else {
$('.left').hide();
}
if (currentIndex === (carouselData.$items.length-1)) {
$('.right').hide();
$('.left').show();
}
else {
$('.right').show();
}
})
Second
$('.carousel .item').each(function(){
var next = $(this).next();
if (!next.length) {
next = $(this).siblings(':first');
}
next.children(':first-child').clone().appendTo($(this));
if (next.next().length>0) {
next.next().children(':first-child').clone().appendTo($(this));
}
else {
$(this).siblings(':first').children(':first-child').clone().appendTo($(this));
}
});
$('#myCarousel').on('slid', '', checkitem);
$(document).ready(function(){
checkitem();
});
function checkitem()
{
var $this = $('#myCarousel');
if($('.carousel-inner .item:first').hasClass('active')) {
$this.children('.left.carousel-control').hide();
} else if($('.carousel-inner .item:last').hasClass('active')) {
$this.children('.right.carousel-control').hide();
} else {
$this.children('.carousel-control').show();
}
}
Here I used the second JavaScript example and made what you want:
$('.left').hide();
$('#carousel-example-generic').on('slid.bs.carousel', function (ev) {
var carouselData = $(this).data('bs.carousel');
var currentIndex = carouselData.getActiveIndex();
if (currentIndex >= 1) {
$('.left').show();
}
else {
$('.left').hide();
}
if (currentIndex === (carouselData.$items.length-1)) {
$('.right').hide();
$('.left').show();
}
else {
$('.right').show();
}
})

I am trying to get the index of several carousels from bootstrap. At this moment I get only the index of one carousel.

Here need a string with the index of all carousel
var params = "Data :"+$scope.currentBaseIndex+":"+$scope.currentAnteIndex+":"+$scope.currentManoIndex;
The problem is that all values are the index of the first carousel (id="Carousel-roboticArmB")
EXAMPLE
1º carousel index: 2
2º carousel index: 4
3º carousel index: 1
Expected output: "Data :4:2:1"
Real output: "Data :2:2:2"
Solved
$scope.currentBaseIndex = $("div.active#base").index() + 1;
$scope.currentAnteIndex = $("div.active#ante").index() +
$scope.currentManoIndex = $("div.active#mano").index() + 1;
The solution was change the position of ID and class.
Hope someone will find this helpful.
