背景视频播放列表

Question

我有本教程中的视频背景设置：https://slicejack.com/video-background-playlist/。 我无法让播放列表正常工作。谁能帮我？ 播放列表中有两个视频可以播放，但只有第一个可以播放。 所有视频都托管在 github 上。 我在 codepen 上有设置：https://codepen.io/SEGACD32XMODEL1/pen/xxbwRdB?editors=1000

<div id="video-player" class="fullscreen-bg">
<video class="fullscreen-bg__video" autoplay muted poster="img/BLUE_DOTS.jpg" preload>
    <source src="https://robocop79.github.io/video/I Got a Boner! - Spongebob.mp4" 
type="video/mp4">
</video>
<div class="fullscreen-bg__playlist">
    <a href="https://robocop79.github.io/video/I Got a Boner! - Spongebob.mp4" class="current- 
video"></a>

Answer 1

在视频标签下添加这些

  <source src="https://robocop79.github.io/video/I Got a Boner! - Spongebob.mp4" 
      type="video/mp4">
      <source src="https://robocop79.github.io/video/I Got a Boner! - Spongebob.ogv" 
      type="video/mp4">
      <source src="https://robocop79.github.io/video/I Got a Boner! - Spongebob.webm" 
      type="video/mp4">

---

或者只在js代码中保留这个

source[0].src = videoDirectory + linkList[index] + '.mp4';
