JavaScript decorator pattern

August 25th, 2006

Decorator pattern in JavaScript? Sure can do. Read the article on how to augment arbitrary JavaScript objects with custom before and after events.

Basically, it boils down to this:


actsAsDecorator(Ajax.InPlaceEditor.prototype);
Ajax.InPlaceEditor.prototype.after(
  'enterEditMode', function() {
    // do something
  }
);

Nicely done, and very useful to add your own tweaks to existing JavaScript controls and components.
