我正在尝试使用javascript和<iframe>标签播放youtube视频。到目前为止，我收到此错误：“ document.getElementById（...）。playVideo不是函数”。这是我的代码：
JavaScript：
document.getElementById("video").playVideo();
HTML：
<iframe id="video" src="url"> </iframe>
尝试播放youtube视频javascript时出现“ .playVideo不是功能”

您是否要自动播放视频？在这种情况下，您需要在youtube URL的末尾添加？autoplay = 1，并向您的iframe代码添加一个allow属性，如下所示
<iframe src="https://www.youtube.com/embed/VIDEO_ID?autoplay=1" allow='autoplay'></iframe>
如果您想使用JavaScript来控制视频播放器，建议您使用Youtube Player API。示例代码如下（摘自youtube文档）-
<!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',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>
</html>
