change javascript opacity

[garevn]

Is there any chance to change the opacity of this player? i have no idea...

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<div id="player-holder"></div>
<script type="text/javascript">

var options = {};
options.playlistXmlPath = "player/playlist/playlist.xml";
options.firstColor = "00FFFF";
options.secondColor = "ee1d24";
options.backColor = "000000";
options.highlightAlpha = "100";
options.fontSize = "large";
options.loopPlaylist = "true";
options.shufflePlaylist = "true";
options.autoLoad = "true";
 var params = {};
 params.allowScriptAccess = "always";
 swfobject.embedSWF("player/swf/OriginalMusicPlayerPlaylist.swf", "player-holder", "250", "250", "9.0.0","expressInstall.swf", options, params, {});
</script>

i tried to use a table-div with the opacity i want but it doesnt work..

Why would this have anything (directly) to do with JavaScript? If CSS can't change the opacity, JavaScript can't. JavaScript can only change the same things with regard to opacity (and other styles) that CSS can.

Anyway, this is a Flash player, and Flash seems to play by its own rules.
