带有猫头鹰旋转木马的 Fancybox (lazyLoad)

Question

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

当我们点击照片时，Fancybox 会弹出照片。然后如果我们点击“下一步”几次以获取 Fancybox 上的下一张照片然后关闭它，猫头鹰传送带上的照片就消失了。

似乎轮播已经改变了它的背景位置并显示了由于lazyLoad 选项而尚未加载的照片。有谁明白这里发生了什么？我花了很多时间在这上面..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“位置焦点返回”功能引起的，您可以通过backFocus : false在初始化时添加来禁用它。

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，如果你滑动足够多并点击其中一张克隆幻灯片，fancybox 将以默认选项开始（因为克隆也有data-fancybox="images"属性）。有一个针对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有什么索引。

这是一个可能的解决方案 - https://codepen.io/fancyapps/pen/yGYWNy?editors=1010（请注意，我已删除data-fancybox="images"并添加了data-index属性）。
