How to add captions for images in owl carousel

Question

I'm using own carousel, so to add caption I followed this question on stack overflow but it didn't work for me. Then I checked using inspect element and found that their is no 'active' class on my carousel current image. So I added script to do so. In the end my script look like this

$(document).ready(function() {
    $('.owl-carousel').owlCarousel({
        loop: true,
        items: 1,
        afterAction: function(el) {
            //remove class active
            this
                .$owlItems
                .removeClass('active')

            //add class active
            this
                .$owlItems
                .eq(this.currentItem)
                .addClass('active')
        },

        onInitialized: function() {
            var activeImg = $('.owl-carousel').find('.active').find('img');
            var comment = activeImg.attr('alt');
            var title = activeImg.attr('title');
            if (comment) $('.image-caption').html('<h4>' + title + '</h4><p>' + comment + '</p>');
        }
    });

    owl = $('.owl-carousel').owlCarousel();
    $('.prev').click(function() {
        owl.trigger('prev.owl.carousel');
    });
    $('.next').click(function() {
        owl.trigger('next.owl.carousel');
    });

    owl.on('translated.owl.carousel', function(event) {
        var activeImg = $(this).find('.active').find('img');
        var comment = activeImg.attr('alt');
        var title = activeImg.attr('title');
        if (comment) $('.image-caption').html('<h4>' + title + '</h4><p>' + comment + '</p>');
    });
});

The script is not working properly.

Answer 1

In this solution i am using HTML figcaption element that represents a caption or a legend associated with a HTML figure.

Also i have added all the needed logic at OWL Carousel afterMove after move callback:

$('.owl-carousel').owlCarousel({
    loop: true,
    items: 1,
    navigation: true,
    pagination: true,
    lazyLoad: true,
    singleItem: true,
    afterMove: function(elem) {
        var current = this.currentItem;
        var currentImg = elem.find('.owl-item').eq(current).find('img');

        $('figure')
            .find('img')
            .attr({
                'src': currentImg.attr('src'),
                'alt': currentImg.attr('alt'),
                'title': currentImg.attr('title')
            });
        $('#figcaption').text(currentImg.attr('title'));
    }
});

.owl-carousel .owl-item img {
    display: block;
    width:80%;
    height:100px;
}
