我疯了,试图解决这个问题,它不会像我希望的那样工作,啊,我觉得自己像个孩子:/
var videoID;
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
videoID = sessionStorage.getItem("key");
var onYouTubeIframeAPIReady = function(){
player = new YT.Player('player', {
height: '315',
width: '560',
videoId: videoID,
events: {

}
});
}
//The API will call this function when the video player is ready.

console.log(videoID);
}

这是一个问题:
function onYouTubeIframeAPIReady(){
player = new YT.Player('player', {
height: '315',
width: '560',
videoId: videoID,
events: {
'onReady': onPlayerReady
}
});
}
如何删除此播放器对象并在点击事件上创建一个新对象? 我真的希望这个工作,请有人帮忙:))
答案 0 :(得分:2)
您是否有特定原因需要销毁播放器对象并重新创建它?如果您的目标只是加载新视频,则可以随时执行此操作:
$('div.search-box a').on('click', function(){
player.loadVideo($(this).data("id"));
sessionStorage.setItem('key', $(this).data("id"));
});
(您可能需要声明播放器变量,使您的点击处理程序可以访问其范围,无论是作为全局范围等)。
但是,如果你真的需要销毁播放器本身并重新创建它,我想知道问题在于,在你点击的时候,你并没有改变&#39; videoID&#的价值39;变量(onYouTubePlayerAPIReady函数需要实例化新播放器);相反,您只需更改sessionStorage键的值。
