Intro
OOP is a great concept, it simplifies the programmer’s life, especially in the field of interface development. Nearly all modern web-interfaces use JS in some way – for field highlighting, validation, help etc. It’s OK when there are such simple things.
And now imagine, that we have a set of dialogue windows (HTML+CSS) for adding a comment, rating, sending to the friend. Each of these boxes has a number of functions – check if user is logged in(if not – show login form), send AJAX request, process response, show error/success messages, position the box on the page etc.
