如何解决 Swiper 和 Video.Js 之间的事件冲突

Question

我正在使用 Swiper 制作包含图像和视频的简单幻灯片。这就像一个魅力。但是，因为设计要求是要有一个一致且好看的播放器UI，所以我需要使用Video.js作为视频播放器。所以我有 Swiper 作为幻灯片插件和 Video.js 作为视频插件。除了这两个插件 .

之间存在事件冲突外，这是有效的
Swiper 在其根上有一个 mousedown 事件，而 Video.js 在视频及其（由 Video.js 动态创建的）父容器上也有一个 mousedown 事件。当拖动幻灯片（视频）时，不仅 Swiper 检测到它必须滑动，而且 Video.js 也会将其处理为点击视频。 因此，如果您滑动到下一张幻灯片，这始终意味着视频是 played/paused。

此外，当您在时间轴上拖动圆圈时，Swiper 也会检测到滑动。

是否有机会修补两个事件侦听器以协同工作？我正在寻找一种无需修补库本身的方法。此外，补丁不应影响插件的原始行为。

这是我要引用的代码。你也可以玩 this jsfiddle.

var swiper = new Swiper('.swiper-container', { pagination: '.swiper-pagination', paginationClickable: true, nextButton: '.swiper-button-next', prevButton: '.swiper-button-prev', spaceBetween: 30 }); [...document.querySelectorAll('video')].forEach(video => { video.classList.add('video-js'); video.classList.add('vjs-default-skin'); video.classList.add('vjs-big-play-centered'); videojs(video, { fluid: true, autoplay: true }); });

html, body { position: relative; height: 100%; } body { background: #eee; font-family: Helvetica Neue, Helvetica, Arial, sans-serif; font-size: 14px; color: #000; margin: 0; padding: 0; } .swiper-container { width: 100%; height: 100%; } .swiper-slide { text-align: center; font-size: 18px; background: #fff; /* Center slide text vertically */ display: -webkit-box; display: -ms-flexbox; display: -webkit-flex; display: flex; -webkit-box-pack: center; -ms-flex-pack: center; -webkit-justify-content: center; justify-content: center; -webkit-box-align: center; -ms-flex-align: center; -webkit-align-items: center; align-items: center; }

Answer 1

您可以将 class 添加到选项 noSwipingClass 以防止 Swiper 处理带有 class 的幻灯片上的事件。现在只有 next/prev 滑动按钮可以在视频幻灯片上使用。也许是一个合理的妥协。

例如。

var swiper = new Swiper('.swiper-container', {
  nextButton: '.swiper-button-next',
  prevButton: '.swiper-button-prev',
  spaceBetween: 30,
  noSwipingClass: 'swiper-no-swiping'
});

与：

<!-- Swiper -->
<div class="swiper-container">
  <div class="swiper-wrapper">
    <div class="swiper-slide swiper-no-swiping" oncouseo>
      <video preload="auto" muted loop controls>
        <source src="https://dwknz3zfy9iu1.cloudfront.net/uscenes_h-264_hd_test.mp4" type="video/mp4">
      </video>
    </div>
    <div class="swiper-slide">Slide 2</div>
    <div class="swiper-slide swiper-no-swiping">
      <video preload="auto" muted loop controls>
        <source src="https://dwknz3zfy9iu1.cloudfront.net/uscenes_h-264_hd_test.mp4" type="video/mp4">
      </video>
    </div>
    <div class="swiper-slide">Slide 4</div>
    <div class="swiper-slide">Slide 5</div>
  </div>
  <!-- Add Arrows -->
  <div class="swiper-button-next"></div>
  <div class="swiper-button-prev"></div>
</div>

另一种方法，但更符合您的要求，是在视频上添加叠加层，并且只将点击事件传递给视频。

它将叠加层拉伸到视频区域的大小，同时排除底部的视频控制栏。

在 div 控制栏中添加 class 'swiper-no-swiping' 以阻止视频手势被 Swiper 识别。

现在，在叠加层上滑动不会导致视频播放或暂停，但点击它会，并且视频控制栏的手势将被 Swiper 忽略。

当然，可见的 CSS 和文字只是为了帮助说明叠加层，将被删除。

var swiper = new Swiper('.swiper-container', {
  pagination: '.swiper-pagination',
  paginationClickable: true,
  nextButton: '.swiper-button-next',
  prevButton: '.swiper-button-prev',
  spaceBetween: 30,
  noSwipingClass: 'swiper-no-swiping'
});

[...document.querySelectorAll('video')].forEach(video => {
  video.classList.add('video-js');
  video.classList.add('vjs-default-skin');
  video.classList.add('vjs-big-play-centered');
  videojs(video, {
    fluid: true,
    autoplay: true
  });
});

$(function() {

  var $overlay = $("#video-overlay1");
  var myPlayer = videojs('vid1');
  var $overlayArea = $("#vid1 > .vjs-text-track-display");

  // apply overlay on video to prevent swipes playing/pausing the video
  positionVideoOverlay();

  // prevent swiping action on video control bar
  $(".vjs-control-bar").addClass("swiper-no-swiping");

  $overlay.click(function() {
    if (myPlayer.paused())
      myPlayer.play();
    else
      myPlayer.pause();
  });

  $(window).resize(function() {
    positionVideoOverlay();
  });

  function positionVideoOverlay() {
    $overlay.css("width", $overlayArea.width() + "px");
    $overlay.css("height", $overlayArea.height() + "px");
    $overlay.css("top", $overlayArea.offset().top + "px")
  }
});

.video-overlay {
  position: absolute;
  left: 0;
  top: 0;
  font-size: 20px;
  font-family: Helvetica;
  color: #FFF;
  background-color: rgba(50, 50, 50, 0.8);
}

<div class="swiper-container">
  <div class="swiper-wrapper">
    <div class="swiper-slide">
      <video id="vid1" preload="auto" muted loop controls>
            <source src="https://dwknz3zfy9iu1.cloudfront.net/uscenes_h-264_hd_test.mp4" type="video/mp4">
          </video>
      <div id="video-overlay1" class="video-overlay">Overlay that will pass clicks to video layer
        <br>But will not pass swipe gestures</div>
    </div>
    <div class="swiper-slide">Slide 2</div>
    <div class="swiper-slide">Slide 3</div>
  </div>
  <!-- Add Pagination -->
  <div class="swiper-pagination"></div>
  <!-- Add Arrows -->
  <div class="swiper-button-next"></div>
  <div class="swiper-button-prev"></div>
</div>

Answer 3

这样只会为视频js的控制栏设置无滑动

$( ".vjs-control-bar" ).addClass('swiper-no-swiping');

滑动仍然适用于视频 div。

Answer 4

与 Manev 的回答类似，带有选项 noSwipingClass: 'vjs-control-bar' 的 init Swiper 也可以。

var swiper = new Swiper('.swiper-container', {
  noSwipingClass: 'vjs-control-bar'
});
