Tips for removing a particular slide from bootstrap carousel with JQuery

I'm a beginner when it comes to bootstrap. I have a Carousel with some slides that include a Decline button. When the button is clicked, I want to delete/remove that slide and move on to the next one. Can this be achieved using JQuery? I've been experimenting with something similar in JSFiddle.

var $carousel = $('#myCarousel'),
    $carouselItems = $('.item', $carousel);

$carousel.on('slid.bs.carousel', function (e) {
    $carouselItems.removeClass('prev next');
    var $active = $(e.relatedTarget);
    $active.next().addClass('next');
    $active.prev().addClass('prev');
})

$(document).ready(function(){
    $("button").click(function(){
        $("#div1").remove();
         $("#li1").remove();
        $("#li2").attr("data-slide-to",0);
         $("#li2").attr("data-slide-to",1);
         $("#div2").addClass('active');
    });
});

Any help would be greatly appreciated. Thank you.

When a button is clicked, the script will identify the active slide and remove it from the DOM. It will then set the next .item element as active.

JavaScript:

var $carousel = $('#myCarousel');
$("button").click(function() {
  currentIndex = $('div.active').index();
  var ActiveElement = $carousel.find('.item.active');
  ActiveElement.remove();
  var NextElement = $carousel.find('.item').first();
  NextElement.addClass('active');
});

.content-area {
    position: relative;
    width: 460px;
    margin: 0 auto;
}
.carousel-indicators li {
    border-radius: 50%;
    height: 20px;
    width: 20px;
}
.carousel-indicators .active {
    height: 25px;
    width: 25px;
}

            <li data-target="#myCarousel" id="li3" data-slide-to="2"></li>
        </ol>
        <!-- Wrapper for slides -->

This piece of coding brilliance really saved the day for me. I attempted to manipulate the carousel on my own but ended up freezing it. Your code solved my problem perfectly. One small observation though, there seems to be a redundant line of code present: currentIndex = $('div.active').index(); It looks like the currentIndex variable from this line is not being used anywhere in the code.
