Create node/module objects and be able to treat them as dom insertable nodes. Requires jQuery. Combined with jqPersist the object can be persisted with the node and linked up again later to maintain instance values etc.

sample.js

(function ($) {
    
    var myP = function (arg) {
        this.init('<p />');
        
        if (typeof $.fn.persist$ === 'function') {
            this.persist$();
        }
        
        this.text(arg);
        
        this.test = function () {
            console.log(this.text());
        };
    };
    
    myP.prototype = $();
    
    $(function () {
        var $body = $('body');
        
        $body.append(new myP('one'));
        $body.append(new myP('two'));
        
        $body.children('p').each(function () {
            if (typeof $.fn.get$ !== 'function') {
                return;
            }
            
            $(this).get$().test();
        });
    });

})(jQuery);
