The function that triggers an image slide event in Bootstrap 4 carousel

Currently, I have implemented a bootstrap 4 carousel with 11 slides that are functioning as intended. I now have another div (#div-info) where I would like to display specific text and images based on the active carousel slide. For example, when slide 2 is active, I want to display text as SLIDE 2 and fixed images related to slide 2 in the div (#div-info). As the carousel transitions to the next slide (slide 3), I want different text and images to be displayed in the div (#div-info).

Although I have looked into the "slide.bs.carousel" event, I have not been able to find a suitable solution. Any assistance would be greatly appreciated. I am relatively new to JavaScript and jQuery, but I am committed to trying my best to follow any instructions provided.

Answer №1

Consider using the event slid.bs.carousel.

As outlined in the documentation:

$('#myCarousel').on('slid.bs.carousel', function (ev) {
  // perform actions on slide change
  console.log(ev.from, ev.to)
})

Answer №2

Utilizing the carousel-caption class in Bootstrap 4 allows you to easily add text and images within a carousel. To customize the appearance, CSS can be used to style the images and fonts. Below is an example code snippet from the Bootstrap 4 documentation:

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
        <ol class="carousel-indicators">
            <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
        </ol>
        <div class="carousel-inner">
            <div class="carousel-item active">
                <img class="d-block w-100" src="img01.png" alt="First slide">
                <div class="carousel-caption d-none d-md-block">
                    <h5>First Slide</h5>
                    <img class="d-block w-100" src="img02.png" alt="First slide" >
                </div>
            </div>
            <div class="carousel-item">
                <img class="d-block w-100" src="img02.png" alt="Second slide">
                <div class="carousel-caption d-none d-md-block">
                    <h5>Second Slide</h5>
                    <img class="d-block w-100" src="img03.png" alt="Second slide" >
                </div>
            </div>
            <div class="carousel-item">
                <img class="d-block w-100" src="img03.png" alt="Third slide">
                <div class="carousel-caption d-none d-md-block">
                    <h5>Third Slide</h5>
                    <img class="d-block w-100" src="img01.png" alt="Third slide" >
                </div>
            </div>
        </div>
        <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>
    </div>
