无法触发 Youtube 的 Iframe-API – 未定义的 "loadVideoByUrl('...')"
Cannot fire "loadVideoByUrl('...')" of Youtube's Iframe-API – undefined
看来我在这里遗漏了一些明显的东西,但我无法得到
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player1');
// here everything is fine and I can see the
// function as part of player
console.log(player);
// but here it says "player.loadVideoByUrl()" undefined
player.loadVideoByUrl("https://youtu.be/bHQqvYy5KYo");
player.playVideo();
}
上班。有什么想法吗?
提前致谢!
我假设在您调用 loadVideoByUrl
函数时 player
没有初始化。在文档中,他们使用
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
玩家事件。播放器对象似乎是异步构造的。因此,如果您使用这些事件,代码将如下所示:
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player1', {
events: {
'onReady': onPlayerReady
}
});
}
function onPlayerReady(){
player.loadVideoByUrl("https://youtu.be/bHQqvYy5KYo");
player.playVideo();
}
