<script>
  (function iife() {
    "use strict";

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

</script>

Answer 1

只需将hide类添加到play按钮并将document.querySelector(".playButton").classList.remove("hide");添加到hideClickedElement函数即可。
