how to check if a function exists in Flex?

[mayanks20]

Hi,

I am wondering if there is any method to check if a function exists in Actionscript/Flex.

The same way as we do isdefined in javascript.

Thank you

On instances - use Object hasOwnProperty method - all objects in AS3 inherit from Object:

var mc:MovieClip = new MovieClip();

var s:Sprite = new Sprite();

trace(mc.hasOwnProperty("play")); // true

trace(s.hasOwnProperty("play")); // false
