Keep them coming, I’ll probably write a post about how many different ways of using private variables in an object

Here is a simpler example:

function test(){
var rot=”a”;
this.rotted=function(){return rot};
}

var test2 = new test()
alert(test2.rot); //Returns undefined
alert(test2.rotted()); //Returns a

Simpler sample:

function test(){
var rot=”a”;
this.rotted=function(){return rot};
}
var test2 = new test()
alert(test2.rot); //returns undefined
alert(test2.rotted()); //returns a

Also, why not simply do

function PrivateCats() {
// This is the list of cat names
var nameList = [];

// This is a private method
var lastCat = function() {
// Note : I don’t use “this” to access private variables
// thanks to the power of closures!
return nameList[nameList.length-1];
}

// These are our public methods!
// This is where we create another scope to
// avoid external objects to use the private variables.
this.add = function(name) {
// Note : once again, I don’t use “this”
// to access the private variables and methods
nameList.push(name);
return lastCat();
},
this.names = function() {
return nameList;
}
}

Seems even more simple I think… And works the same since this isn’t in the same scope as the var declarations. Maybe I missed something… I’m starting to become rusted in JS
