Fancybox with Owl carousel (lazyLoad)

Question

我正在使用 Fancybox v3.5.4 和 Owl 带有 lazyLoad 选项的 carousel v2.3.4

当我们点击一张照片时，Fancybox 会弹出照片。然后，如果我们点击 "Next" 几次以获取 Fancybox 上的下一张照片，然后将其关闭，owl 轮播中的照片就会消失。

由于 lazyLoad 选项，轮播似乎改变了背景位置并显示尚未加载的照片。有谁知道这里发生了什么？我在这上面花了很多时间.. 谢谢

你可以在这里看到一个例子： https://codepen.io/Philippe_12/pen/bOVOrK

$('.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'
  ]
});

.img_container{ width:50%}

Answer 1

看起来这个问题是由 fancybox 的 "place-focus-back" 功能引起的，您可以通过在初始化时添加 backFocus : false 来禁用它。

您可能没有注意到的另一个问题是您仅在 "non-cloned" 项上初始化了 fancybox。这意味着，如果您滑动足够多并单击其中一张克隆的幻灯片，fancybox 将以默认选项启动（因为克隆也将具有 data-fancybox="images" 属性）。有一个为其他滑块解决此问题的示例 - 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（请注意，我删除了 data-fancybox="images" 并添加了 data-index 属性）。
