响应式：调整大小时幻灯片消失

Question

我在幻灯片中使用了响应式断点。在小屏幕上，我一次显示一张幻灯片。在大 2 上（大意味着小于990 像素）

示例：我将断点设置为在小屏幕上一次显示 1 张幻灯片，并在大屏幕上禁用 slider。我有8 幻灯片。在大于990 像素的屏幕中。

如果我在小屏幕上导航到幻灯片并再次使屏幕变大，则此块中的每张幻灯片都会消失。

您可以在codepen查看它

如果我删除这部分代码

responsive: [{
                breakpoint: 568,
                settings: {
                    slidesToShow: 1
                }
            }]

一切都会好起来的

请帮助任何人

这是我的配置Slick slider

$(window).on('load', function(){
    if($(window).width() < 990){
     $('.container-slick').slick({
          centerMode: true,
          infinite: true,
          prevArrow: false,
          nextArrow: false,
          speed: 200,
          slidesToShow: 2,
          slidesToScroll:1,
          autoplay:true,
            responsive: [{
                breakpoint: 568,
                settings: {
                    slidesToShow: 1
                }
            }]
        });
    }
  });
$(window).on('resize', function(){
    if($(window).width() < 990){
     $('.container-slick').not('.slick-initialized').slick({
          centerMode: true,
          infinite: true,
          prevArrow: false,
          nextArrow: false,
          speed: 200,
          slidesToShow: 2,
          slidesToScroll:1,
         // if you remove from here
            responsive: [{
                breakpoint: 568,
                settings: {
                    slidesToShow: 1
                }
            }]
            // to there everything will work but i need 1 slide in small screens and 2 in screens more than 568 pixels
        });
    }
    else{
      $(".container-slick.slick-initialized").slick("unslick");
    }
  });

使用 setTimeout

$(window).on('load', function(){
    if($(window).width() < 990){
     $('.container-slick').slick({
          centerMode: true,
          infinite: true,
          prevArrow: false,
          nextArrow: false,
          speed: 200,
          slidesToShow: 2,
          slidesToScroll:1,
          autoplay:true,
            responsive: [{
                breakpoint: 568,
                settings: {
                    slidesToShow: 1
                }
            }]
        });
    }
  });
$(window).on('resize', function(){
    if($(window).width() < 990){
      setTimeout(function(){
        $('.container-slick').not('.slick-initialized').slick({
          centerMode: true,
          infinite: true,
          prevArrow: false,
          nextArrow: false,
          speed: 200,
          slidesToShow: 2,
          slidesToScroll:1,
            responsive: [{
                breakpoint: 568,
                settings: {
                    slidesToShow: 1
                }
            }]
        });
      },100)

    }
    else{
    setTimeout(function(){  $(".container-slick.slick-initialized").slick("unslick"); },100)  
    }
  });

请参考下面的小提琴

Fiddle

$(document).ready(function(){
  if($(window).width() < 1200){
   initializeSlick()
  }


  $(window).on('resize', function(){
    if($(window).width() < 1200){
      $(".container-slick.slick-initialized").slick("unslick");
    } else if(!$('.container-slick').hasClass('slick-initialized')) {
      initializeSlick()
    }
  });


    function initializeSlick() {
      $('.container-slick').slick({
