javascript - 单独播放/暂停多个 HTML5 视频

Question

任何人都可以帮我重写以下代码，使其在不使用 ID 的情况下工作，以便我可以将其用于单个页面上的多个视频吗？预先感谢您!!

HTML MARKUP

<div id="video-container">
    <video id="video" width="640" height="365" src="https://d3vv6lp55qjaqc.cloudfront.net/items/3V3g280Q1z441P071g3E/tnt-lidcap-web.mp4" type="video/mp4" autoplay loop muted></video>
    <div id="video-controls">
        <button id="play-pause" type="button" aria-label="toggle pause play">
            <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 120 120" width="120" height="120">
              <circle cx="60" cy="60" r="60" fill="#000" fill-opacity=".5" />
              <path stroke="#fff" stroke-linecap="round" stroke-width="10" d="M74.933 33v54M45.067 33v54" id="pauseIcon" class="video-pause" style="visibility: visible" />
              <path fill="#fff" stroke="#fff" stroke-linejoin="round" stroke-width="8" d="M54 33L54 87 81 60z" id="playIcon" class="video-play" style="visibility: hidden" />
            </svg>
        </button>
    </div>
</div>

JAVASCRIPT (WORKS FOR SINGLE VIDEO)
window.onload = function() {

  var video = document.getElementById("video");
  var playButton = document.getElementById("play-pause");
  var pauseIcon = document.getElementById("pauseIcon");
  var playIcon = document.getElementById("playIcon");

    playButton.addEventListener("click", function() {
        if (video.paused == true) {
            video.play();
            pauseIcon.style.visibility ="visible";
            playIcon.style.visibility ="hidden";
        } else {
            video.pause();
            pauseIcon.style.visibility ="hidden";
            playIcon.style.visibility ="visible";
        }
    });
}

您可以用 class 替换每个 id 并使用 .querySelectorAll() 执行相同的任务。

onload = e => {
  const containers = document.querySelectorAll('.video-container'):
  containers.forEach(container => {
    const video = container.querySelector('video');
    const playButton = container.querySelector('button');
    playButton.addEventListener('click', e => {
    // do stuff
    })
  })
}
