YouTube API获取当前视频标题

我有一个播放Youtube播放列表的无铬Youtube iframe api播放器。所有的工作都很好，但我想在一个div中显示当前播放视频的标题下面的播放器，但我不知道如何做到这一点，任何帮助将非常感激。

我试过stackoverflow的其他例子，但它们是内联播放列表，是不切实际的对于一个有100多个视频的youtube播放列表，我的剧本知识非常有限，我从来没有让他们工作而谷歌API网站似乎并没有涵盖我所寻找的。我尝试了jwplayer，它可以获得标题，但shuffle功能很差，一遍又一遍地播放相同的视频有时一个视频多次播放。我找到了一个可以解决shuffle问题的脚本，但是我丢失了get标题函数。我决定继续使用youtube，希望有人能帮助我。

所以再一次，我真的很感谢任何帮助与这个谢谢。这是我的

<!DOCTYPE html>
<html>
<body>
  <div id="player"></div>
    <script>
    var tag = document.createElement('script');
    tag.src = "https://www.youtube.com/iframe_api";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    var player;
    function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
    height: '390',
    width: '640',
    playerVars : { 'rel' : 0,  'showinfo' :0, 'autoplay': 1, 'controls': 0 },
    events: {
    'onReady': onPlayerReady 
    }
    });
    }
    var getRandom = function(min, max) {
    return Math.random() * (max - min) + min;
    `enter code here`};

      var playRandomTrack = function() {
      num = getRandom(0, 99);
      player.playVideoAt(num);  
      };
  function onPlayerReady(event) {
  player.loadPlaylist({'listType': 'playlist', 'list': 'PLmc_AnfxCB6t6Lwwgx3x5OxfNOWwHluU-','index': '99','startSeconds': '0','suggestedQuality': 'hd720'});
  player.setShuffle({'shufflePlaylist' : 1});
  }
</script>
</body>
</html>

为第一个视频添加onPlayerReady():

var intId = setInterval( function() {
    // Check if player is initialized and the video is loaded
    if ( player ) {
        // States: 1: playing, 2: paused, 5: stopped
        if ( [ 1, 2, 5 ].indexOf( player.getPlayerState() ) >= 0 ) {
            // Set the innerText of div with id="title" to player title
            document.getElementById( "title" ).innerText = player.getVideoData().title;
            clearInterval( intId );
        }
    }
}, 100 );

并添加到playRandomTrack():

// Delay the loop because otherwise player.getPlayerState() still returns 1 because the previous video is not unloaded yet
setTimeout( function() {
    var intId = setInterval( function() {
        if ( [ 1, 2, 5 ].indexOf( player.getPlayerState() ) >= 0 ) {
            document.getElementById( "title" ).innerText = player.getVideoData().title;
            clearInterval( intId );
        }
    }, 100 );
}, 100 );

所以你的整个代码变成了:

<!DOCTYPE html>
<html>
<body>
    <div id="player"></div>
    <div id="title"></div>
    <script>
        var tag = document.createElement( 'script' );
        tag.src = "https://www.youtube.com/iframe_api";
        var firstScriptTag = document.getElementsByTagName( 'script' )[0];
        firstScriptTag.parentNode.insertBefore( tag, firstScriptTag );
        var player;
        function onYouTubeIframeAPIReady() {
            player = new YT.Player( 'player', {
                height: '390',
                width: '640',
                playerVars: {
                    'rel': 0,
                    'showinfo': 0,
                    'autoplay': 1,
                    'controls': 0
                },
                events: {
                    'onReady': onPlayerReady
                }
            } );
        }
        var getRandom = function( min, max ) {
            return Math.random() * ( max - min ) + min;
        };
        var playRandomTrack = function() {
            num = getRandom( 0, 99 );
            player.playVideoAt( num );
            setTimeout( function() {
                var intId = setInterval( function() {
                    if ( [ 1, 2, 5 ].indexOf( player.getPlayerState() ) >= 0 ) {
                        document.getElementById( "title" ).innerText = player.getVideoData().title;
                        clearInterval( intId );
                    }
                }, 100 );
            }, 100 );
        };
        function onPlayerReady( event ) {
            player.loadPlaylist( {
                'listType': 'playlist',
                'list': 'PLmc_AnfxCB6t6Lwwgx3x5OxfNOWwHluU-',
                'index': '99',
                'startSeconds': '0',
                'suggestedQuality': 'hd720'
            } );
            player.setShuffle( {
                'shufflePlaylist': 1
            } );
            var intId = setInterval( function() {
                if ( player ) {
                    if ( [ 1, 2, 5 ].indexOf( player.getPlayerState() ) >= 0 ) {
                        document.getElementById( "title" ).innerText = player.getVideoData().title;
                        clearInterval( intId );
                    }
                }
            }, 100 );
        }
    </script>
</body>
</html>

我发现上面的实现不适合我，所以我想出了我自己的版本，我认为它更优雅。

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

var player;
function onYouTubeIframeAPIReady() {
    player = new YT.Player( 'player', {
        height: '390',
        width: '640',
        playerVars: {
            'rel': 0,
            'showinfo': 0,
            'autoplay': 1,
            'loop': 1,
            'autohide': 1,
            'color': 'white',
            'theme': 'light',
            'controls': 1
        },
        events: {
            'onReady': onPlayerReady
        }
    } );
}
var num = (1 + Math.floor(Math.random() * 10));
function onPlayerReady( event ) {
    /*player.addEventListener('onStateChange', function(e) {
        console.log('State is:', e.data);
    });*/
    player.addEventListener('onStateChange', 'onPlayerStateChange');
    player.loadPlaylist( {
        'listType': 'playlist',
        'list': 'PLbfrQv4OD4BDMDrxuFv3uxwZeOKzkTkut',
        'index': num,
        'startSeconds': '0',
        'suggestedQuality': 'hd720'
    } );
    player.setShuffle( {
        'shufflePlaylist': 1
    } );
}
function onPlayerStateChange( event ) {
    console.log(player.getPlayerState()) 
    if (player.getPlayerState() == 1) {
    document.getElementById( "title" ).innerText = player.getVideoData().title;
    }
}
