Fancybox + Flickity。 iOS方向问题

Question

在 Fancybox 模式中 window 我有 Flickity 轮播。在 iPad 上，当我更改方向时，Flickity 停止正常工作。 flickity-viewport 显示为 0px。桌面 window 调整大小没有问题。不确定 iPad 方向发生变化时如何更新 Flickity。

$(document).ready(function() {
  $('.carousel-container').each( function( i, container ) {

      imagesLoaded: true,

Answer 1

我认为这是因为 fancybox 在设备方向更改事件中暂时隐藏了内容，也许尝试为 fancybox 添加这个，看看是否有帮助：

onUpdate : function( instance, slide ) {
    slide.$slide.find('.carousel-main').flickity('resize');
    slide.$slide.find('.carousel-nav').flickity('resize');
}
