How can i detect Adobe AIR version through javascript?

I wa开发者_开发知识库nt to detect the adobe AIR version through javascript..how to do that?

You can use this variable NativeApplication.nativeApplication.runtimeVersion in javascript you can use air.NativeApplication.nativeApplication.runtimeVersion after including air alias file

I don't know how are you going to use it, but it is better to check for supported features rather than checking for version.
