Fancybox + Flickity。iOS方向问题

Question

在Fancybox模式窗口中，我有Flickity carousel。在iPad上，当我更改方向时，Flickity停止正常工作。flickity-视口显示为0px。调整桌面窗口大小没有问题。不确定当iPad上的方向更改时如何更新Flickity。

$(document).ready(function() {
  $('.carousel-container').each( function( i, container ) {
    var $container = $( container );
    // main Flickity
    var $carouselMain = $container.find('.carousel-main').flickity({
      imagesLoaded: true,
      percentPosition: false,
      pageDots: false,
      adaptiveHeight: true
    });
    // nav Flickity
    $container.find('.carousel-nav').flickity({
      asNavFor: $carouselMain[0],
      contain: true,
      pageDots: false,
      groupCells: true,
      adaptiveHeight: true,
      prevNextButtons: false
    });
  });

  $("[data-fancybox]").fancybox({
    idleTime : false,
    smallBtn: false, 
    buttons : [
      'close'
    ],
    touch : {
       vertical : false,
       momentum : false
    },
    wheel : false,
    afterShow: function( instance, slide ){
      slide.$slide.find('.carousel-main').flickity('resize');
      slide.$slide.find('.carousel-nav').flickity('resize');
    }

Answer 1

我认为这是因为fancybox在设备方向改变事件中暂时隐藏了内容，也许可以尝试为fancybox添加以下内容，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');
}
