swf not transparent + div opacity chrome & opera on osx

Ok i got some weird stuff here I just no clue anymore.

First my swf file not going transparent, even when ensure wmode is transparent. non off the browsers is working... the swf is embedded but is not transparent. i even tried removing some params, but still the same... so what's wrong?

<div id="flashContent">

        <script type="text/javascript" src="<?php bloginfo('template_url'); ?>/js/swfobject.js"></script>
        <script type="text/javascript">


                var flashvars = {};
                flashvars.domain = "*";
                var params = {};
                params.movie = "myflash.swf";
                params.quality = "best";
                params.play = "true";
                params.loop = "false";
                params.menu = "false";
                params.wmode = "transparent";
                params.bgcolor = "#626262";
                params.scale = "noscale";
                params.allowfullscreen = "false";
                params.allowscriptaccess = "always";
                params.allownetworking = "all";
                var attributes = {};
                attributes.id = "myflash";
                swfobject.embedSWF("<?php bloginfo('template_url'); ?>/include/myflash.swf", "flashContent", "100", "100", "10.0.0", flashvars, params, attributes);



        </script>

    </div>

second so i was going to use css to force the div to go transparent using opacity modes. ha, but chrome & opera on the 开发者_高级运维Mac OSX not going opacity at all ><

I even force them using important, and tried all possible codes i know...

-webkit-opacity: 0 !important; -moz-opacity: 0 !important; -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)" !important; filter: alpha(opacity=0) !important; opacity: 0 !important;

well any have a clue what i am doing wrong?

It could be because your passing the params object in the wrong spot

swfobject.embedSWF("<?php bloginfo('template_url'); ?>/include/myflash.swf", "flashContent", "100", "100", "10.0.0", flashvars, params, attributes);

Try this:

swfobject.embedSWF("<?php bloginfo('template_url'); ?>/include/myflash.swf", "flashContent", 100, 100, "10.0.0", false, flashvars, params, attributes, false);
