很奇怪。当有另一个简单的 iframe 时，事件不会触发。我删除了 iframe - 它起作用了。
带有额外 iframe 的 html：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1255">

</head>
<body>
<iframe id="player_2" src="http://player.vimeo.com/video/XXXXXXX?title=0&byline=0&portrait=0&api=1&player_id=player_2&autoplay=1" width="782" height="413" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>
<iframe src="/homestuff/googleads/index.html" width="1" height="1" style="border:0;" ></iframe>

vimeo-0905.js 是我从游乐场复制的简单事件捕捉器。在没有 iframe 的情况下完美运行：
