javascript - 单击主页按钮时，视频应停止

Question

我希望有人能帮助解决这个问题。

我想要做的是在点击主页按钮后让视频停止。

我怎样才能让它在代码中发挥作用？

主页按钮是 X https://jsfiddle.net/bosqhk4f/

点击 X 后，视频应该停止。

CSS

<button class="home" type="button" aria-label="Close">

Answer 1

我在您的代码中发现了一个错误，这就是代码无法按预期工作的原因。你的函数看起来像:

function onPlayerReady(event) {
    const player = event.target;
    player.setVolume(100);

    const stopButton = document.querySelectorAll(".home");
    stopButton.addEventListener("click", function() {
      player.stopVideo();
    });
  }

在 const stopButton = document.querySelectorAll(".home"); 行中，您选择所有选择器类 home 和 stopButton 是结果中的一个数组，但是您尝试为该数组调用 addEventListener 方法，这就是它不起作用的原因。

只需将函数 onPlayerReady 替换为以下代码:

function onPlayerReady(event) {
    const player = event.target;
    player.setVolume(100);

    const stopButtons = document.querySelectorAll(".home");
    stopButtons.forEach(function (button) {
      button.addEventListener("click", function() {
        player.stopVideo();
      });
    });
  }

您应该使用 forEach 方法将事件监听器添加到每个 .home 选择器。

一切如您所愿。我在你的 JSFiddle 中检查过它。
