A common embedded flash object is often written in HTML:
<div id="playerDiv">
Hello, you either have JavaScript turned off or an old version of Macromedia's Flash Player. <a href="http://www.macromedia.com/go/getflashplayer/">Get the latest Flash player</a>.
</div>
<script type="text/javascript">
// <![CDATA[
var fo = new SWFObject("/player2.swf?video_id=xxxxx", "movie_player", "450", "370", 7, "#FFFFFF");
fo.write("playerDiv");
// ]]>
</script>
To get the information of object,
In Mozilla/Firefox,
var vidHolder=document.getElementById('playerDiv');
var vid=vidHolder.getElementsByTagName('embed')[0];
In Internet Explorer,
var vidHolder=document.getElementById('playerDiv');
var vid=vidHolder.getElementsByTagName('object')[0];
To get information parsed to object,
In Mozilla/Firefox,
var src = vid.src; (width, height, style ...)
In Internet Explorer,
var src = vid.movie; (width, height, style ...)
