Question

我正在使用jquery通过iframe加载YouTube视频，以减少初始页面加载时间。使用此方法 - 只有视频缩略图与页面一起加载，当用户点击播放按钮时，实际播放器会加载。但是AutoPlay不适用于Android和Iphone，尽管它完全可以在使用Windows的台式机上运行。当我搜索这个问题时，事实证明“iPhone和Android上的Chrome和Safari浏览器只允许在用户交互启动时播放HTML5视频。它们阻止嵌入式媒体自动播放，以防止通过蜂窝网络主动下载。”我想自动播放视频。请帮忙。

这是我的jquery

document.addEventListener("DOMContentLoaded",
    function() {
        var div, n,
            v = document.getElementsByClassName("youtube-player");
        for (n = 0; n < v.length; n++) {
            div = document.createElement("div");
            div.setAttribute("data-id", v[n].dataset.id);
            div.innerHTML = YouTubeThumb(v[n].dataset.id);
            div.onclick = YouTubeIframe;
            v[n].appendChild(div);
        }
    });

function YouTubeThumb(id) {
    var thumb = '<img src="https://i.ytimg.com/vi/ID/mqdefault.jpg">',
        play = '<div class="play"></div>';
    return thumb.replace("ID", id) + play;
}

function YouTubeIframe() {
    var iframe = document.createElement("iframe");
    var embed = "https://www.youtube.com/embed/ID?autoplay=1";
    iframe.setAttribute("src", embed.replace("ID", this.dataset.id));
    iframe.setAttribute("frameborder", "0");
    iframe.setAttribute("allowfullscreen", "1");
    this.parentNode.replaceChild(iframe, this);
}

和HTML

<div class="youtube-player" data-id="YouTube_Video_ID"></div>

Answer 1

试试这个例子： -

  // 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');

  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an  (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '390',
      width: '640',
      videoId: 'M7lc1UVf-VE',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.playVideo();
  }

  // 5. The API calls this function when the player's state changes.
  //    The function indicates that when playing a video (state=1),
  //    the player should play for six seconds and then stop.
  var done = false;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING && !done) {
      setTimeout(stopVideo, 6000);
      done = true;
    }
  }
  function stopVideo() {
    player.stopVideo();
  }
