I spent the day searching for a good solution to detecting plugins such as Shockwave, Flash, Quicktime, etc. The final solution was using http://www.pinlady.net/PluginDetect/. It was as easy as generating the javascript file, adding it to my solution, and adding the following script to my page. <![CDATA[ PluginDetect.getVersion(‘.’); var v = PluginDetect.getVersion(‘Flash’); var isInstalled = (PluginDetect.isMinVersion(‘Flash’, ‘0’) >= 0 ? true : false); if (isInstalled) document.write(“Adobe Flash (” + v + “) is installed.”) else document.write(“Adobe Flash is disabled. Get Adobe Flash.”) ]]>
