HTML video element control does not display

Question

I created a video element and set the controls attribute to true, but the controls are not showing (even on hover)

if (!this._player) {
    this._player = document.createElement('video');
}

this._player.controls = true;
this._player.src = xxxxx;

Also set the width of the video element to 100% The location of the container is relative

What should I do to display the default video controls

Answer 1

This code will create a video element with default controls. The video element will be positioned absolutely and fill the entire screen. When the video starts playing or is paused, the event listener logs a message to the console.

// 获取视频元素
const video = document.querySelector("video");

// 为视频控件添加事件监听器
video.addEventListener("play", function() {
  console.log("视频开始播放");
});

video.addEventListener("pause", function() {
  console.log("视频暂停");
});

video {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

<video controls> 
    <source id='mp4' src="http://media.w3.org/2010/05/sintel/trailer.mp4" type='video/mp4' />
</video>
