Use behaviors to write data entry fields that restrict input, custom scrollbar objects, calendar widgets, or indeed any functionality or custom control you want to reuse.

Behaviors: More Reusable, Object-Oriented Code

Use behaviors to write data entry fields that restrict input, custom scrollbar objects, calendar widgets, or indeed any functionality or custom control you want to reuse. And use new group features that make it easier to use them as reusable containers.

Accelerate your coding, share and reuse your code with behaviors. Behaviors are implemented by setting a property of an object to point to a source script. The source script then "lives" in the object as if it was part of the object. Make a change in your script and all linked objects automatically update.
