Good example OO JS?

Can someone point me in the right direction of some real object oriented javascript? I learn OO for javascript from several books, but all of the examples in these books come down to a canine object inherited from an animal prototype or the like. I really want to see something more substantial.

I looked at jQuery and similar libraries (base, prototype), but I consider them examples. I was looking for a script where I see visible inheritance (classic or protoypal).

Good examples of the “real world” for learning OO javascript is to really learn some of the javascript frameworks. Some of them support and use OO in their own framework code:

They provide an excellent link and various strategies for writing JavaScript JavaScript.

IMO, the prototype javascript thingie is very useful, and classic OOP is not needed.

As an example in the real world, consider the google maps v3 api . Let the new OverlayView be implemented: 


// implement an OverlayView //
MyOverlay.prototype = new google.maps.OverlayView();

// the "constructor" function // function MyOverlay (position, node, map) {// set the parameters // this.position = position; this.node = node; this.map = map; this.setMap (this.map); }

// required onAdd function // MyOverlay.prototype.onAdd = function() { // observe the getPanes function inherited from OverlayView // var panes = this.getPanes(); // bla bla // }

// required draw function // MyOverlay.prototype.draw = function() { // bla bla // } // .. other functions //

// now instantiate an object // var instance = new MyOverlay(position, node, map);

, (, Prototype, dojo, jquery ..) .
