Display the carousel title when hovering over the image

I am having an issue with my Bootstrap 4 carousel. I am attempting to make the carousel caption only display when hovered over, but nothing is showing up when I hover over the image.

There are no error messages in the console, so it's unclear what I may have overlooked. One potential cause I considered was the carousel sliding automatically, but even after removing that feature, the caption still does not appear on hover.

The Carousel:

<div id="NewsCarousel" class="carousel slide default-div-top-padding" data-ride="carousel">

                    <!-- Indicators -->
                    <ul class="carousel-indicators">
                        <li data-target="#NewsCarousel" data-slide-to="0" class="active"></li>
                        <li data-target="#NewsCarousel" data-slide-to="1"></li>
                        <li data-target="#NewsCarousel" data-slide-to="2"></li>
                    </ul>

                    <!-- The slideshow -->
                    <div class="carousel-inner">

                        <div class="carousel-item active">
                            <img src="~/images/Resources/HomePage/knowledgeLatestNews.jpg" alt="imgAlt" style="width:650px;height:350px">
                            <div class="carousel-caption">
                                <a href="#"><h3>Los Angeles</h3></a>
                                <p>We had such a great time in LA!</p>
                            </div>
                        </div>

                        <div class="carousel-item">
                            <img src="~/images/Resources/HomePage/knowledgeLatestNews.jpg" alt="imgAlt" style="width:650px;height:350px">
                            <div class="carousel-caption">
                                <a href="#"><h3>Los rtr</h3></a>
                                <p>We had such a great time in LA!</p>
                            </div>
                        </div>

                        <div class="carousel-item">
                            <img src="~/images/Resources/HomePage/knowledgeLatestNews.jpg" alt="imgAlt" style="width:650px;height:350px">
                            <div class="carousel-caption">
                                <a href="#"><h3>Los Angeasdales</h3></a>
                                <p>We had such a great time in LA!</p>
                            </div>
                        </div>

                    </div>

                    <!-- Left and right controls -->
                    <a class="carousel-control-prev" href="#NewsCarousel" data-slide="prev">
                        <span class="carousel-control-prev-icon"></span>
                    </a>
                    <a class="carousel-control-next" href="#NewsCarousel" data-slide="next">
                        <span class="carousel-control-next-icon"></span>
                    </a>

 </div>

Javascript:

<script type="text/javascript">

    $(document).ready(function () {

        $('.carousel-caption').hide();
        $('img[alt = imgAlt').on('hover', function () {
            $('.carousel-caption').fadeIn();
        });
    });

</script>

I'm unsure of what I may have missed in my JavaScript code. Additionally, if there is a cleaner or better way to achieve this effect using only CSS, any suggestions would be greatly appreciated.

Thank you in advance.

Answer №1

To achieve a pure CSS solution, you can create a fading effect for the caption by hovering over the .carousel-inner element. Here's how you can do it:

.carousel-caption{
  opacity:0;
  transition:500ms ease-in-out;
}
.carousel-item:hover .carousel-caption{
  opacity:1;
}

Answer №2

Kindly refer to these instructions in order to find your solution. Additionally, explore the Bootstrap 4 Carousel page for further assistance. https://getbootstrap.com/docs/4.1/components/carousel/

.carousel-caption {
  opacity: 0;
  -webkit-transition: all 0.4s;
  transition: all 0.4s;
  color: #fff;
}

.carousel-item:hover .carousel-caption {
  opacity: 1;
}

Answer №3

To achieve the same effect, you can utilize the mouseenter and mouseout events.

$(document).ready(function () {

    $('.carousel-caption').hide();
    $('img[alt = imgAlt]').mouseenter(function () {
        $('.carousel-caption').show();
    }).mouseout(function(){
        $('.carousel-caption').hide();
    });
});

Answer №4

It is possible that the selector being used to access the image is returning nothing due to incorrect syntax. For proper guidance on attribute selectors in jQuery, you can refer to this link.

To troubleshoot this issue, you can easily print it out in the console:

console.log($('img[alt = imgAlt'));

Try accessing the image this way instead:

$('img[alt="imgAlt"').on('hover', function () {
    $('.carousel-caption').fadeIn();
});
