When doing client-side developing there are times that jQuery’s get-this-do-that nature doesn’t provide all that is needed. For more complex applications I usually find myself creating javascript objects that ‘control’ a specific part of the page’s interaction. In the objects the application’s state is tracked, references to other objects (could be relevant DOM nodes) are stored and event handlers are set.

One of the problems typically encountered when dealing with javascript event handlers is that they have their own take on the ‘this’ keyword. Closures to the rescue.
