JavaScript: Cross-browser "browser plugin" detection

I'm looking for a script that will allow me to detect if a user has 开发者_如何学CWindows Media Player installed, or Quicktime, or Flash, or Silverlight...

Ideally, this would be jQuery plugin, but any script will do.

Do you know of one you can recommend?

PluginDetect seems to work pretty good. You can generate a minified version of the script and only select the plugins you want to detect and functions you need.

Try jqPlugin.

Apple has written a script to do this. With it you can run functions like:

• detectQuickTime()
• detectFlash()
• detectDirector()
• detectWindowsMedia()
• detectReal()
