Question

我正试图通过Youtube API找到一种方法，在另一个视频播放时暂停一个视频，我在同一页面上有多个Youtube嵌入。是否有一个简单的代码，我完全错过了？

      <div id="video_youtube" style="min-height:600px; margin-top:1%;">
        <iframe id='player1' style="margin-right:2%; padding-bottom:1%;" width="500px" height="281px" src="http://www.youtube.com/embed/rZye11nxOOQ" frameborder="0" allowfullscreen>
          </iframe>
        <iframe id='player2' style="padding-bottom:1%;" width="500px" height="281px" src="http://www.youtube.com/embed/8Q89hEnkYH4" frameborder="0" allowfullscreen>
          </iframe>
     </div>

我找到了一个显示代码的代码，可以让你对两个视频做同样的事情，但我认为如果我不得不添加更多视频，那么这些代码太过手动，会变得越来越复杂。

 <div id="player1"></div>
 <div id="player2"></div>
 <script>
   var tag = document.createElement('script');
   tag.src = "//www.youtube.com/iframe_api";
   var firstScriptTag = document.getElementsByTagName('script')[0];
   firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

var player;
function onYouTubeIframeAPIReady() {
    player1 = new YT.Player('player1', {
        height: '293',
        width: '520',
        videoId: 'zXV8GMSc5Vg',
        events: {
            'onStateChange': onPlayerStateChange
        }
    });
    player2 = new YT.Player('player2', {
        height: '293',
        width: '520',
        videoId: 'LTy0TzA_4DQ',
        events: {
            'onStateChange': onPlayerStateChange
        }
    });
}

function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING) {
        stopVideo(event.target.a.id);
    }
}

function stopVideo(player_id) {
    if (player_id == "player1") {
        player2.stopVideo();
    } else if (player_id == "player2") {
        player1.stopVideo();
    }
}
</script>

如果您创建了一个包含所有玩家对象的对象，并确保引用每个玩家的属性名称与该玩家的ID相匹配，该怎么办？然后你的stop方法可以只做一个简单的javascript for ... in ...循环（循环遍历属性名而不是值）：

 <div id="player1"></div>
 <div id="player2"></div>
 <!-- add as many as you need -->
 <script>
   var tag = document.createElement('script');
   tag.src = "//www.youtube.com/iframe_api";
   var firstScriptTag = document.getElementsByTagName('script')[0];
   firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

var player={};
function onYouTubeIframeAPIReady() {
    player.player1 = new YT.Player('player1', {
        height: '293',
        width: '520',
        videoId: 'zXV8GMSc5Vg',
        events: {
            'onStateChange': onPlayerStateChange
        }
    });
    player.player2 = new YT.Player('player2', {
        height: '293',
        width: '520',
        videoId: 'LTy0TzA_4DQ',
        events: {
            'onStateChange': onPlayerStateChange
        }
    });
    // add more here, ensuring that in player.[whatever] the 'whatever' is the same as the ID. You could very easily script this process as well so you don't repeat yourself.
}

function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING) {
        stopVideos(event.target.a.id);
    }
}

function stopVideos(player_id) {
    for (p in player) {
        if (p!==player_id) {
          player[p].stopVideo(); // all videos will stop playing except the one that triggered the event
        }
    }
}
</script>
