我已经使用 java 脚本 IFrame Player API 实现了 youtube 播放器。在此我可以播放视频,但在视频播放完毕后,它会显示推荐的视频列表,同时单击它会自动在新选项卡中打开。我需要在选项卡本身中打开它。如何实现。我参考了文档但无法获取。

<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 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 <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
playerVars: {
'playsinline': 1,
'rel':0
},
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();
}
</script>
</body>

为此,您需要在 YT.Player 构造函数中向 playerVars 对象添加一个参数 rel=0。这将在视频播放结束时删除相关视频。
另外,您可以使用onStateChange事件检测视频何时结束,然后使用player.loadVideoById()方法重新加载视频,参数autoplay=1,会自动开始播放视频,防止相关视频被播放显示。
修改后的代码:
<!DOCTYPE html>
<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 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 <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
playerVars: {
'playsinline': 1,
'rel': 0
},
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.ENDED && !done) {
player.loadVideoById({
'videoId': 'M7lc1UVf-VE',
'startSeconds': 0,
'suggestedQuality': 'hd720',
'autoplay': 1,
'playsinline': 1,
'rel': 0
});
done = true;
}
}
</script>
</body>
</html>
修改后,视频结束会自动重启,相关视频不会显示。该视频也将在同一选项卡中播放,而不是在新选项卡中打开。
为此,可以在创建
playerVars
实例时使用YT.Player
参数,将origin
参数的值设置为当前域。这将防止推荐的视频在新选项卡中打开,而是在同一选项卡中打开。
这是带有
origin
参数集的代码的更新版本:

tag.src = "https://www.youtube.com/iframe_api";
