我复制的一则讯息代码,并修改了一些。自动播放我的电脑正常工作(使用javascript),但不能在iPad上。我一直在试图与自动播放:1内onYouTubeIframeAPIRead,但它并不能帮助。
<!-- 1. The <iframe> (and video player) will replace this <div> tag.-->
<div id="player">
</div>
// 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: '100%',
width: '100%',
videoId: '<?php echo $video;?>',
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, <?php echo $length*1000+2000;?>);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
iOS的自动播放模块在具有音频轨道,并通过一个处理程序,它不是在同一个直接背景下的用户交互autoplayed视频。

你会想这个绑定到一个处理程序,并保持相同的整体背景下,使自动播放是允许的。我相信,Chrome的也将很快实施这一政策。
