Behaviors are a way to attach new functionality to DOM elements which match certain CSS selectors.
Behaviors are encapsulated, reusable bits of functionality. They interact with elements via public APIs - listening to events and reading and writing properties. Examples of behaviors include selectability, drag and drop, or input validation.
Behavior is the interface or base class for Behaviors. It has a named
Behavior.attach that takes the element the behavior is attached
to. It then has a single method
detach that's called when the behavior should
registerBehavior registers a CSS selector with a
for a specific node. Using the active_query package, the node is monitored for
changes, and when an element matches the selector a new behavior instance is
created with the factory. When an element is removed or changed so that it no
longer matches the selector, the behavior is detached.
getBehaviors returns all the behaviors currently attached to a node.
