javascript - Flashplayer 与 html5

Question

是否有办法检测浏览器是否安装了 html5 或支持的 Flash 播放器？有什么 JavaScript 技巧吗？就像下面的代码一样。

<!--<noscript>
        <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="${width}" height="${height}" id="${application}">
            <param name="movie" value="${swf}.swf" />
            <param name="quality" value="high" />
            <param name="bgcolor" value="${bgcolor}" />
            <param name="allowScriptAccess" value="sameDomain" />
            <param name="allowFullScreen" value="true" />
            <!--[if !IE]>-->
            <object type="application/x-shockwave-flash" data="${swf}.swf" width="${width}" height="${height}">
                <param name="quality" value="high" />
                <param name="bgcolor" value="${bgcolor}" />
                <param name="allowScriptAccess" value="sameDomain" />
                <param name="allowFullScreen" value="true" />
            <!--<![endif]-->
            <!--[if gte IE 6]>-->
                <p> 
                    Either scripts and active content are not permitted to run or Adobe Flash Player version
                    ${version_major}.${version_minor}.${version_revision} or greater is not installed.
                </p>
            <!--<![endif]-->
                <a href="http://www.adobe.com/go/getflashplayer">
                    <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash Player" />
                </a>
            <!--[if !IE]>-->
            </object>
            <!--<![endif]-->
        </object>
    </noscript> -->     

任何想法将不胜感激。
