在我的js上播放和播放视频的奇怪行为

Question

我得到一个丑陋的＆＃34;未捕获（在承诺中）DOMException：play（）请求被对pause（）＆＃34;的调用中断。我试图用视频卡排队。当鼠标进入卡片时，海报图像消失，视频将播放。当鼠标离开时，视频应该停止，或者，如果鼠标进入另一张卡，则当前视频播放停止，并且可以播放悬停的卡片视频。

有时我会得到上面的错误，但我无法检测到什么时候发生。此外，当鼠标悬停时，海报图像四处移动非常笨拙，如何删除视频帧上的边框？以下是我使用

的javascript

＆＃13;

＆＃13;

   var videostrip = (function () {
    var videos = []; 
    var currentVideoIndex = 0;
    var fullscreenAPISupported = false;
    var videoIdsInOrder = [];

     function init() {
       iniVideoButtons();
       if ('ontouchstart' in document) {
         $('body').removeClass('no-touch');
       }
     }

     function iniVideoButtons() {
       var currentHoverIndex = -1;
       var greyedOutClass = 'video-button--inactive';
       var $videoButtons = $('.video-button');
       var didTouchEvent = false;
       var touchOnEnter = false;

       $('body').on('touchstart', function() {
         didTouchEvent = true;
       });

       $videoButtons.on('mouseenter', function() {
         touchOnEnter = didTouchEvent;
         if (didTouchEvent) {
           didTouchEvent = false;
           return;
         }
         var index = $(this).data('index');

         if (index !== currentHoverIndex) {
           currentHoverIndex = index;

           var video = $(this).children('.video-button__video')[0];
           $(video).css('display', 'block');
           if (video.currentTime != 0) video.currentTime = 0;

          $(this).children('.video-button__image').css('opacity', 0);
          video.play();
         }
       });

       $videoButtons.on('mouseleave', function() {
         if (touchOnEnter) {
           touchOnEnter = false;
           return;
         }

         var index = $(this).data('index');
         if (index === currentHoverIndex) {
           currentHoverIndex = -1;
         }

         var video = $(this).children('.video-button__video')[0];
         video.pause();

         $(this).children('.video-button__image').css('opacity', 1);
       });
     }
     return {
       init: init
     };
    })();
    $(document).ready(videostrip.init);
