Question

希望您能提供帮助。

试图使我的视频全屏显示，但无法。

使用了MDN规范及其代码以对我有所帮助。

JAVASCRIPT

/* Get Our Elements */

const player = document.querySelector('.player');
const video = player.querySelector('.viewer');
const progress = player.querySelector('.progress');
const progressBar = player.querySelector('.progress__filled');
const toggle = player.querySelector('.toggle');
const skipButtons = player.querySelectorAll('[data-skip]');
const ranges = player.querySelectorAll('.player__slider');
const fullScreen = player.querySelector('.fullscreen__button');

/*Build our functions */


// Play and Pause video
function togglePlay(){
  if (video.paused){
    video.play();
  } else {
    video.pause();
  }
}

// Update Buttons when pausing
function updateButton(){
  const icon = this.paused ? '►' : '❚ ❚';
  toggle.textContent = icon;
}

// Update
function skip (){
  video.currentTime += parseFloat(this.dataset.skip);
}

function handleRangeUpdate(){
  video[this.name] = this.value;
}

function handleProgress(){
  const percent = (video.currentTime / video.duration) * 100;
  progressBar. style.flexBasis = `${percent}%`;
}

function scrub(e){
  const scrubTime = (e.offsetX / progress.offsetWidth) * video.duration;
  video.currentTime = scrubTime;
}

function makeItBigger(){
  if (!document.fullscreenElement) {
     document.documentElement.requestFullscreen();
 } else {
   if (document.exitFullscreen) {
     document.exitFullscreen();
   }
 }
}
/* Hook up event listenrs*/

video.addEventListener('click', togglePlay);
video.addEventListener('play', updateButton);
video.addEventListener('pause', updateButton);
video.addEventListener('timeupdate', handleProgress);
toggle.addEventListener('click', togglePlay);
fullScreen.addEventListener('click', makeItBigger);

skipButtons.forEach(button => button.addEventListener('click', skip));
ranges.forEach(range => range.addEventListener('change', handleRangeUpdate));

let mousedown = false;
progress.addEventListener('click', scrub);
progress.addEventListener('mousemove', (e) => mousedown && scrub(e));
progress.addEventListener('mousedown', () => mousedown = true);
progress.addEventListener('mouseup', () => mousedown = false);

全屏模式将应用于整个窗口，而不仅仅是我的视频。我可以看到功能正常工作，可能不是正确的选择。

我希望我的实际视频（黑色背景）改为全屏显示。
