I'm working on a site and using JQuery for essentially the first time. I've mostly used MooTools for previous projects, and I have a few widget classes I've written using the MooTools Class structure. I'd like to port them over to JQuery, but it looks to me like there is nothing similar to the MooTools functionality when it comes to object classes.

I've searched around a bit, and haven't found much on it. Digg appears to have rolled their own, but I'm not sure if this is something I should be using. Is there a better way? How object-oriented do people normally get with JQuery? What's the usual method of encapsulating a UI widget (or any functional class structure)?

I'll post a fake example of a possible MooTools widget class:

var ZombatWidget = new Class({

    Extends: BaseWidget,

    widgetPropertyX = 'prop1',

    widgetPropertyY = 'prop2',

    attach = function(el) {

        var f = function() { 

            //do something widgety

        };

        el.addEvent('dblclick',f);

        el.addClass('widgetized');

    }

});



var z = new ZombatWidget();

z.attach($('widgetDiv'));

What I've got is a lot bigger than that, but you get the idea. Do I need to convert this to the prototype method of class/inheritance structuring? How would you write this kind of object class using JQuery?
