Slick.js 和 html5 视频自动播放和暂停

Question

是否可以将 slick.js 与 html5 自托管视频一起使用，无需用户交互即可播放和暂停视频？

我目前有以下代码，它有一个带有垂直光滑幻灯片的双滑块和一个主要部分，其中大图像和视频将出现并自动滚动。这将在电视上进行，因此不会有用户交互。

如何让包含视频的幻灯片在出现后完全播放，并在播放结束后继续播放并无限期重复。视频可能包含各种长度，因此需要动态检测长度。

我尝试在 this question 上实现代码，但是我的示例无法正常工作。

是的，可以使用 JavaScript。
当视频幻灯片变成 currentSlide 您需要：

暂停滑块
播放视频

您可以使用 slick.js 事件 afterChange:

$('.sliderMain').on('afterChange', function(event, slick, currentSlide){
  if (currentSlide == 5) {
    $('.sliderMain').slick('slickPause');
    myVideo.play();
  }
});

您还需要为视频何时结束添加一个事件侦听器，以便让滑块继续播放。您可以这样做：

document.getElementById('myVideo').addEventListener('ended',myHandler,false);
function myHandler(e) {
    $('.sliderMain').slick('slickPlay');
}

如果您在这方面遇到问题，请添加一个 JSFiddle，我会尽力帮助您。

编辑：这是一个有效的 JSFiddle

$(document).ready(function() {
  $('.sliderMain').slick({
    slidesToShow: 1,
    slidesToScroll: 1,
    arrows: false,
    fade: true,
    asNavFor: '.sliderSidebar',
    autoplay: true,
    autoplaySpeed: 3000
  });
  $('.sliderSidebar').slick({
    slidesToShow: 5,
    slidesToScroll: 1,
    asNavFor: '.sliderMain',
    dots: false,
    centerMode: false,
    focusOnSelect: true,
    vertical: true,
    arrows: false
  });
  $('.sliderMain').on('afterChange', function(event, slick, currentSlide) {
    if (currentSlide == 5) {
      $('.sliderMain').slick('slickPause');
      theVideo.play();
    }
  });

  document.getElementById('theVideo').addEventListener('ended', myHandler, false);

  function myHandler(e) {
    $('.sliderMain').slick('slickPlay');
  }
});
