我举了一个例子:

我想添加一个视频背景,比如图像背景 例如,类似以下内容的mp4视频:

步骤1)添加HTML:

<!-- The video -->
<video autoplay muted loop id="myVideo">
  <source src="rain.mp4" type="video/mp4">
</video>

<!-- Optional: some overlay text to describe the video -->
<div class="content">
  <h1>Heading</h1>
  <p>Lorem ipsum...</p>
  <!-- Use a button to pause/play the video with JavaScript -->
  <button id="myBtn" onclick="myFunction()">Pause</button>
</div>
/* Style the video: 100% width and height to cover the entire window */
#myVideo {
  position: fixed;
  right: 0;
  bottom: 0;
  min-width: 100%;
  min-height: 100%;
}

/* Add some content at the bottom of the video/page */
.content {
  position: fixed;
  bottom: 0;
  background: rgba(0, 0, 0, 0.5);
  color: #f1f1f1;
  width: 100%;
  padding: 20px;
}

/* Style the button used to pause/play the video */
#myBtn {
  width: 200px;
  font-size: 18px;
  padding: 10px;
  border: none;
  background: #000;
  color: #fff;
  cursor: pointer;
}

#myBtn:hover {
  background: #ddd;
  color: black;
}
步骤3)添加JavaScript:

<!-- The video -->
<video autoplay muted loop id="myVideo">
  <source src="rain.mp4" type="video/mp4">
</video>

<!-- Optional: some overlay text to describe the video -->
<div class="content">
  <h1>Heading</h1>
  <p>Lorem ipsum...</p>
  <!-- Use a button to pause/play the video with JavaScript -->
  <button id="myBtn" onclick="myFunction()">Pause</button>
</div>
/* Style the video: 100% width and height to cover the entire window */
#myVideo {
  position: fixed;
  right: 0;
  bottom: 0;
  min-width: 100%;
  min-height: 100%;
}

/* Add some content at the bottom of the video/page */
.content {
  position: fixed;
  bottom: 0;
  background: rgba(0, 0, 0, 0.5);
  color: #f1f1f1;
  width: 100%;
  padding: 20px;
}

/* Style the button used to pause/play the video */
#myBtn {
  width: 200px;
  font-size: 18px;
  padding: 10px;
  border: none;
  background: #000;
  color: #fff;
  cursor: pointer;
}

#myBtn:hover {
  background: #ddd;
  color: black;
}
或者,您可以通过单击按钮添加JavaScript来暂停/播放视频:

<script>
// Get the video
var video = document.getElementById("myVideo");

// Get the button
var btn = document.getElementById("myBtn");

// Pause and play the video, and change the button text
function myFunction() {
  if (video.paused) {
    video.play();
    btn.innerHTML = "Pause";
  } else {
    video.pause();
    btn.innerHTML = "Play";
  }
}
</script>

//获取视频
var video=document.getElementById(“myVideo”);
//扣上按钮
var btn=document.getElementById(“myBtn”);
//暂停并播放视频,然后更改按钮文本
函数myFunction(){
如果(视频暂停){
video.play();
btn.innerHTML=“暂停”;
}否则{
video.pause();
btn.innerHTML=“播放”;
}
}

因此,这不是一项免费的代码编写服务,请您自己尝试实现这一点,如果在此过程中出现任何问题,请尝试。我们很乐意提供帮助。您也可以在保存视频标签的div上使用
z-index
,将其设置在较低的层上。
