我正在使用带有lazyLoad选项的Fancybox v3.5.4和Owl carousel v2.3.4
当我们点击照片时，Fancybox 就会弹出照片。然后，如果我们点击几次“下一步”以获取 Fancybox 上的下一张照片，然后关闭它，猫头鹰轮播上的照片就消失了。
由于lazyLoad选项，轮播似乎已经改变了背景位置并显示尚未加载的照片。有人明白这是怎么回事吗？我花了很多时间在这上面..谢谢

$('.owl-carousel').owlCarousel({
items: 4,
loop:true,
pagination: false,
slideSpeed: 700,
paginationSpeed: 700,
rewindSpeed: 700,
lazyLoad: true
});
$().fancybox({
selector : '.owl-item:not(.cloned) a',
hash : false,
thumbs : {
autoStart : true
},
buttons : [
'zoom',
'download',
'close'
]
});

看起来这个问题是由 fancybox 的“放置焦点返回”功能引起的，您可以通过添加来禁用它backFocus : false初始化时。
您可能没有注意到的另一个问题是您仅在“非克隆”项目上初始化了 fancybox。这意味着，如果您滑动足够多并单击克隆幻灯片之一，fancybox 将以默认选项启动（因为克隆将具有data-fancybox="images"属性，也）。有一个为其他滑块解决此问题的示例 -https://fancyapps.com/fancybox/3/docs/#faq-6 https://fancyapps.com/fancybox/3/docs/#faq-6- 但是，您需要对 owlCarousel 进行一些调整，因为它没有添加任何指示每张幻灯片具有什么索引的属性。
这是一个可能的解决方案 -https://codepen.io/fancyapps/pen/yGYWNy?editors=1010 https://codepen.io/fancyapps/pen/yGYWNy?editors=1010（请注意，我已经删除了data-fancybox="images"并添加了data-index属性）。
