In javascript: 1. how do you test if plug ins are enabled? 2. How do you test if flash is enabled? 3. If flash is enabled, how do you test what version it is? thank you
I know there are scripts that detect common plugins, but I'm not sure if it's possible to detect every plugin installed. As for detecting flash and its version number, this kit should do the trick: Adobe Flash Player Detection Kit
SWFObject - http://code.google.com/p/swfobject/ - is the most popular way to deal with flash embedding and any checks that entails out there (bar library agnostic checks like mootools swiff)
For the Gecko based browsers like FireFox the window.navigator.plugins property can be used to list the available plug-ins.
