使用播放按钮隐藏图像

Question

播放按钮的图片在我点击的时候隐藏了，我怎么也隐藏绿色的图片？

这就是我想在代码中做的所有事情。

点击播放图片后隐藏绿色图片。

目前只有播放图隐藏，点击播放图后怎么隐藏绿色图？

css绿色图像

.video-wrapper::after {
  content: "";
  position: absolute;
  left: 0;
  right: 0;
  bottom: 0;
  top: 0;
  border: 1px solid #333;
  pointer-events: none;
  background: url(https://i.imgur.com/ShS6nAO.png) no-repeat;
  background-size: contain;
  background-position: center;
}

javascript

const manageCover = (function makeManageCover() {
  const events = {};

  function show(el) {
    el.classList.remove("hide");
  }

  function hide(el) {
    el.classList.add("hide");
  }

  function fadeVideoIn(cover) {
    hide(cover);
    const videoWrapper = document.querySelector(".video-wrapper");
    videoWrapper.classList.add("slide");
    return videoWrapper;
  }

  function showVideo(videoWrapper) {
    const thewrap = videoWrapper.parentElement.querySelector(".wrap");
    show(thewrap);
  }

  function coverClickHandler(evt) {
    const cover = evt.currentTarget;
    const videoWrapper = fadeVideoIn(cover);
    showVideo(videoWrapper);
    cover.dispatchEvent(events.afterClickCover);
  }

  function init(callback) {
    const cover = document.querySelector(".play");
    cover.addEventListener("click", coverClickHandler);
    events.afterClickCover = new Event("afterClickCover");
    cover.addEventListener("afterClickCover", callback);
  }

  return {
    init
  };
}());

Answer 1

也许你可以尝试添加background: unset; to.video-wrapper.slide::在 class 之后

Answer 2

对于您的问题，将带有按钮的绿色背景作为同一组件更容易。

绿色背景跑不掉的原因：在video-wrapper下设置为伪类以我的经验，javascript是达不到伪类的，即使可以，也会让你的代码超级混乱，难以阅读和遵循。

建议：去掉video wrapper class的绿色背景，移到按钮上。 看这里

HTML

<div class="container">
    <div class="video-wrapper">
        <div class="ratio-keeper">
            <div class="wrap hide">
                <div class="video video-frame"></div>
            </div>
        </div>
    </div>
  <div class="play">
    <button type="button" aria-label="Open"></button>  
  </div>
</div>
