无法关闭音频播放器按钮

Question

我这里有一个可以正常工作的切换播放器。

我无法使用相同的代码让这个工作。

在代码片段中，当您点击它时，音频播放，按钮改变，但只有一次，不会返回。

如何让按钮向后翻转并关闭音频？

Answer 1

错误出在您的 getPause 和 getPlay 函数中。您尝试查找带有 .play class 的按钮，但您的容器包含活动状态，而不是 .play 按钮。如果编辑这两个函数：

   function getPlay(button) {
      return button;
   }

   function getPause(button) {
      return button;
   }

我认为它应该按预期工作。

编辑：第二个解决方案（练习）。您也可以尝试将活动状态添加到 .play 按钮而不是容器。然后你要修改showPauseButton和showPlayButton.

示例：

   function showPauseButton(button) {
     const pause = getPause(button);
      pauseAllButtons();
      hideAllButtons(button);
      show(pause);
      // button.classList.add("active");
      pause.classList.add("active");
   }

(function iife() {
   "use strict";

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

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

   function getButtonContainer(el) {
      while (el.classList.contains("playButton") === false) {
         el = el.parentNode;
      }
      return el;
   }

   function hideAllButtons(button) {
     const buttons = button.querySelectorAll(".play, .pause");
     for (let i = 0; i < buttons.length; i++) {
       hide(buttons[i]);
     }
   }

   function getPlay(button) {
      return button;
   }

   function getPause(button) {
      return button;
   }

   function showPlayButton(button) {
       const play = getPlay(button);
       hideAllButtons(button);
       show(play);
       button.classList.remove("active");
    }
   function isPlaying(button) {
      const play = getPlay(button);
      return play.classList.contains("active");

   }

   function pauseAllButtons() {
     let buttons = document.querySelectorAll(".playButton");
     for (let i = 0; i < buttons.length; i++) {
       if (isPlaying(buttons[i])) {
             showPlayButton(buttons[i]);
       }
     }
   }

   function showPauseButton(button) {
     const pause = getPause(button);
      pauseAllButtons();
      hideAllButtons(button);
      show(pause);
      button.classList.add("active");
   }

      return document.querySelector("audio");
   }

   function playAudio(player, src) {
      player.volume = 1.0;

     }
   }

   function pauseAudio(player) {
      player.pause();
   }

   function manageAudio(player, opts) {
