firefox控制MEDIA PLAYER问题


function Play(){
var player = ' <embed src="'+musicUrl+'" id="blogplayer" height="275"';
player += '  type="application/x-mplayer2" style="display:block"';
player += '  align="baseline" border="0" width="422" pluginspage="http://www.microsoft.com/isapi/redir.dll?prd=windows&sbp=mediaplayer&ar=media&sba=plugin&"';
player += '  name="blogplayer" showcontrols="1" showpositioncontrols="0"';
player += '  showaudiocontrols="1" showtracker="1" showdisplay="0"';
player += '  showstatusbar="1"';
player += '  autosize="0" ';
player += '  showgotobar="0" showcaptioning="0" autostart="0" autorewind="1"';
player += '  animationatstart="0" transparentatstart="0" allowscan="0"';
player += '  enablecontextmenu="1" clicktoplay="0" ';
player += '  defaultframe="datawindow" invokeurls="0">';
player += ' </embed>';
}
$("player").innerHTML = player;
}
    Play("music_url_xxxxxxxxx");
    $("blogplayer").controls.play();firefox中基本代码也就这样
