Hi All, I am using the javascript inheritance helper provided here: http://ejohn.org/blog/simple-javascript-inheritance/

I have the following code, and I have problem accessing the inherited property or function from a closure within a subclass as illustrated below. I am new to OOP javascript code and I appreciate your advice. I suppose within the closure, the context changes to JQuery (this variable) hence the problem. I appreciate your comments.

Thanks, -A

PS - Using JQuery 1.5

     var Users = Class.extend({
                init: function(names){this.names = names;}
            });
            var HomeUsers = Users.extend({
                work:function(){ 
//                alert(this.names.length); // PRINTS A 
//                var names = this.names;  // If I make a local alias it works
                    $.map([1,2,3],function(){
                        var newName = this.names.length; //error this.names is not defined.
                        alert(newName); 
                    });

                }
            });

var users = new HomeUsers(["A"]);
users.work();
