(function iife() {
  "use strict";

  function hideClickedElement(evt) {
    var target = evt.target;
    target.classList.add("hide");
    document.querySelector(".test").classList.remove("hide");
    document.querySelector(".playButton").classList.remove("hide");
  }
  document.querySelector(".playButton").classList.add("hide");
  var cover = document.querySelector(".cover");
  cover.addEventListener("click", hideClickedElement, false);
}());

使用班级hide隐藏播放按钮div onload。然后点击封面元素将其删除。

添加

的z-index：999;

到你的.cover课程

而不是添加

的z-index：1;

到您的.playButton课程。

Answer 3

只需将hide课程添加到播放按钮，然后将document.querySelector(".playButton").classList.remove("hide");添加到hideClickedElement功能。
