我试图在将鼠标悬停在 YouTube 播放器 (iframe) 上时创建缩放效果。

目前,我正在使用 YouTube IFrame Player API 来构建播放器,并触发 onmouseover 事件监听器,以在将鼠标悬停在播放器上时调整播放器的大小。而且似乎不起作用。

http://plnkr.co/edit/TOtWD9?p=preview

function zoom() {
player.setSize(width=200, height=150);
}
document.getElementById('player').addEventListener('onmouseover', zoom);

关于如何运行这个或其他方法有什么想法吗?

最佳答案

我单击了您提供的 plnkr 链接,并发现了您的代码存在的几个问题,因此您无法实现预期/期望的结果:

I modified your code as follows:

HTML:

<!DOCTYPE html>
<html>

<head>
<link rel="stylesheet" href="style.css">

</head>

<body>

<div id="playerHolder"></div><div id="player">stage1</div>
<script src="script.js"></script>
</body>

</html>

反馈: 除非你知道自己在做什么,否则当某些事情发生时(“加载顺序”)如何处理 js,请将 js 放在最后,因为你没有检查 DOM 元素(“player/playerHolder”)是否有在将其绑定(bind)到任何事件之前加载。这有助于防止与绑定(bind)到事件的未定义/空对象相关的错误。

css:

/* Styles go here */
body { width: 100%; height: 100%; }
#playerHolder{
border:2px solid red;
height:100%;
width:100%;
position:absolute;
}

Feedback:

The reason for what I did ( may not be the only way to do it ) is to set perspective "over" the YouTube embed. Note that, as far as I know, you cannot modify third party code from your server, in other words, unless there's a API function that allows you to add custom code, such as you binding a hover event onto the YouTube player, you can't just do it.

js:


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('player', {
height: '390',
width: '640',
videoId: 'SjOLOfyn95U',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}

function onPlayerReady(event) {
event.target.playVideo();
}

var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
//setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}

function zoom() {
player.setSize(width=200, height=150);
}
document.getElementById('playerHolder').addEventListener('mouseover', zoom, false);

反馈:

1) You targeted the Video embed itself, which I explained the issues relating to that on the css section above.
2) You used 'onmouseover', which I replaced with 'mouseover'


I hope this helps solve your problem.
