如何爲貓頭鷹傳送帶中的圖像添加標題

Question

我正在使用自己的傳送帶，因此要添加標題我遵循堆棧溢出this question但它不適用於我。然後我檢查了使用檢查元素，發現他們在我的輪播當前圖像上沒有「主動」類。所以我添加了腳本來這樣做。最後我的腳本看起來像這樣

$(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>'); 
    }); 
}); 

該腳本無法正常工作。

在此解決方案中，我使用HTML figcaption元素表示與HTML figure關聯的標題或圖例。

我也有招回調後添加所有需要的邏輯在OWL CarouselafterMove：

$('.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; 
 
}
