请教一个关于在CHRMOE、OPERA里JS加载FLASH的问题

HTML部分
                        <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
                                id="swfDom" width="800" height="554"
                                codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
                                <param name="movie" value="#" />
                                <param name="wmode" value="Transparent">
                                <param name="quality" value="high" />
                                <param name="bgcolor" value="#ffffff" />
                                <param name="allowScriptAccess" value="sameDomain" />
                                <embed id="swfDom_flash" src="#" quality="high" width="800" height="554" name="Preloader" play="true" loop="false" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer" wmode="transparent"></embed>
                        </object>



JS部分
$("#swfDom").attr("movie","/public/world/swf/Preloader.swf?uid="+"2001");

$("#swfDom_flash").attr("src","/public/world/swf/Preloader.swf?uid="+"2001");



以上写法在IE和 FF里都成功加载，但在CHROME和OPERA里就加载不到 怎么办
