Jinsi ya kumwambaa video juu ya makini

Kamishono - Angalia HTML:

<!-- 视频 -->
<video autoplay muted loop id="myVideo">

</video>
<!-- Chaguo: zawadi za ujumbe za kugawanyika video -->
<div class="content">

  <p>Lorem ipsum...</p>
  <!-- Tumia kifungu kusanya/kusaidia video kwa JavaScript -->
  <button id="myBtn" onclick="myFunction()">Pause</button>
</div>

  position: fixed;
  right: 0;
  bottom: 0;
  min-width: 100%;
  min-height: 100%;
}
/* Ongeza zawadi kwenye chini ya video/kituo cha tovuti */
.content {
  position: fixed;
  bottom: 0;
  background: rgba(0, 0, 0, 0.5);
  color: #f1f1f1;
  width: 100%;
  padding: 20px;
}
/* Kuhariri stili wa kifungu kilichotumiwa kusanya/kusaidia video */

  width: 200px;
  font-size: 18px;
  padding: 10px;
  border: none;
  background: #000;
  color: #fff;

var btn = document.getElementById("myBtn");
// Kusanya na kusaidia video, na kuhariri ujumbe wa kifungu
function myFunction() {
  if (video.paused) {
    video.play();
    btn.innerHTML = "Pause";
  } au kuzunguza {
    video.pause();
    btn.innerHTML = "Play";
  }
}
</script>
