Bootstrap 4 carousel stopped working when running a js script

I am using bootstrap 4 with CDN.

The problem is that I have a boostrap4 carousel (taken from their official site) and it works great, but when I run a js code the carousel images disappear.

this is the carousel code and it works great

But when I click on a button in another div, the carousel images disappear and only the arrows remain on the sides

This is what the other code does:

var jsaccordion = {
  init: function(target) {
    var headers = $("." + target + " .accordion-btn");
    if (headers.length) {
      headers.on('click', jsaccordion.select);
    }
  },

  select: function() {
    var tar = $(this).closest('.accordion-container');
    $('#shared-container').remove();
    if (tar.hasClass('active')) {
      tar.removeClass('active')
    } else {
      $('.active').removeClass('active')
      tar.addClass('active');
      var targText = tar.find('.accordion-text').html();
      var sharedCont = "<div id='shared-container'>" + targText + "</div>";
      if($('body').width() > 768){
        tar = tar.parent();
      }
      tar.after(sharedCont);
    }
  }
}

window.addEventListener('load', function() {
  jsaccordion.init("accordion-container");
});

body {
  max-width: 90%;
  margin: 0 auto;
}

.accordion-container {
  position: relative;
}

.accordion-container button::before {
  content: '+' !important;
}

.accordion-container.active button::before {

}

.accordion-container.active::after {

}

.accordion-container .accordion-text {
  display: none;
  color: #808080;
  padding: 15px;
  border: 1px solid #ffcc4b;
}

#shared-container {
  margin-top: 2rem;

I tried with the js code in the same file and also from another file, but the same thing keeps happening

Answer 1

The problem is that I have a boostrap4 carousel (taken from their official site) and it works great, but when I run a js code the carousel images disappear.

Firstly you need to include boostrap libs, not only the css.

Instantiate the carousel with:

$('.carousel').carousel();

Finally, if you need to toogle active between the accordions this line:

$('.active').removeClass('active')

needs to be changed in:

tar.siblings().removeClass('active');  // toogle active state....

The snippet:

$(function () {

    $('.carousel').carousel();

    var jsaccordion = {
        init: function (target) {
            var headers = $("." + target + " .accordion-btn");
            if (headers.length) {
                headers.on('click', jsaccordion.select);
            }
        },

        select: function () {
            var tar = $(this).closest('.accordion-container');
            $('#shared-container').remove();
            if (tar.hasClass('active')) {
                tar.removeClass('active')
            } else {
                tar.siblings().removeClass('active');
                tar.addClass('active');
                var targText = tar.find('.accordion-text').html();
                var sharedCont = "<div id='shared-container'>" + targText + "</div>";
                if ($('body').width() > 768) {
                    tar = tar.parent();
                }
                tar.after(sharedCont);
            }
        }
    }

    jsaccordion.init("accordion-container");
});

body {
    max-width: 90%;
    margin: 0 auto;
}

.accordion-container {
    position: relative;
}

.accordion-container button::before {
    content: '+' !important;
}

.accordion-container.active button::before {
    content: '-' !important;
}

.accordion-container.active::after {
    content: '';
    width: 0;
    height: 0;
    border-left: 15px solid transparent;
    border-right: 15px solid transparent;
    border-bottom: 15px solid orange;
    position: absolute;
    bottom: -2rem;
    left: 50%;
    transform: translateX(-50%);
    color: orange;
    z-index: 100;
    font-size: 3rem;
    line-height: 1;
}

.accordion-container .accordion-text {
    display: none;
    color: #808080;
    padding: 15px;
    border: 1px solid #ffcc4b;
}

#shared-container {
    margin-top: 2rem;
    display: block;
    width: 100%;
    padding: 2rem;
    border: 1px solid orange;
    text-align: center;
}

#shared-container p {
    margin: 0;
}

@media (max-width: 768px) {
    .col-6 {
        max-width: 100%;
        min-width: 100%;
    }
}
