我有一个带有嵌入式Vimeo视频的网页。
我正在使用javascript和froogaloop进行收听功能，并让它运行起来。在finish上，网页被重定向，我对其进行了编码，以便不能向前跳过播放器。
我正在使用的Vimeo视频受密码保护，因此当页面/视频加载时，它首先提示输入密码。当我输入密码时，它会从视频的开头开始，但ready事件不起作用（或者拿起那里甚至有视频）。我在视频，播放和暂停下有两个按钮。这些不起作用，但我可以通过视频上的播放图标播放视频。所以视频将播放但不支持froogaloop功能。
var vimeoPlayers = document.querySelectorAll('iframe'),
player;
for (var i = 0, length = vimeoPlayers.length; i < length; i++) {
player = vimeoPlayers[i];
$f(player).addEvent('ready', ready);
}
<dd><button class="play">Play</button></dd>
<dd><button class="pause">Pause</button></dd>
如果我刷新页面，它将检测播放器和视频。然后froogaloop的所有功能都可以使用。
我需要保护视频密码。有没有其他方法来检测Vimeo视频或任何人都可以想到修复？
