Using Custom Events

+ +
+

The Custom Event framework is one of the principle communication mechanisms +in YUI. An object can be augmented with EventTarget, enabling it +to be both a host and a target for Custom Events. Custom Events fire from +their host and optionally bubble up to one or more targets. This allows you to +make the interesting moments of your applications broadly available within a +module, within a set of modules, or throughout a complex interface populated +with rich elements.

+ +

In this example, a simple Custom Event is illustrated: +testEvent. This Custom Event is hosted on a Publisher object and +bubbles up to a BubbleTarget object.

+ +

An +illustration of the relationship between the Custom Event, its host, and its +Bubble Target.

+ +

Custom Events, like DOM events, can be stopped +(stopPropagation) and their default behavior can be suppressed +(preventDefault).
