Responding To Dialog Open and Close Events

The jQuery UI dialog widget, just like every other widget, triggers events to reflect changes in state. For example, when a dialog is opened, it enters an "open" state, and the dialogopen event is how this change is communicated to the outside world. This means that any element can listen to these events, including the body element. Listening for dialog events after they've bubbled up the DOM is handy for implementing generic behavior.
