Private & public properties for JavaScript
Here we have a good article about keeping private properties in your JavaScript kinda Java , well we know that JavaScript is not enough good for Object Orientation but it has a lot good parts 
is very flexible.
Here we have the normal way for making "Classes"
//this is like the constructor
};
myClass.prototype.myMethod = function () {
//wow a method :D
};
var myClassInstance = new myClass();
Well we know that everybody who use firebug or javascript pretty often could have access to this objects, so a good way for keep this objects not accesible to the window parent object.. is doing this
var myClass = function () {
//this is like the constructor
};
myClass.prototype.myMethod = function () {
//wow a method :D
};
var myClassInstance = new myClass();
});
And this way is to keep your properties private even from your own objects (I took this method from the Douglas Crockford website), the problem here is that you just access from public to private properties, and private don't have access to public.
function privateMethod() {
alert("Hello I'm the private method");
}
return {
variable:1,
method: function () {
alert(this.variable); // shows 1
},
methodCallPrivate: function () {
privateMethod();
}
}
});
var myClassInstance = new myClass();
myClassInstance.method(); // shows 1
myClassInstance.methodCallPrivate(); //shows "Hello I'm the private method"
But I found this way if you want both have access to each other
var _public = {};
var _private = {};
_public.pubVariable = "Hello World from _public.pubVariable";
_private.priVariable = "Hello World from _private.priVariable";
_public.pubMethod= function() {
alert(_private.priVariable);
};
_private.priMethod = function() {
alert(_public.pubVariable);
};
_public.callpriMethod = function() {
_private.priMethod();
};
return _public;
});
var myClassInstance = new myClass();
myClassInstance.pubMethod(); // shows "Hello World from _private.priVariable"
myClassInstance.callpriMethod(); // shows "Hello World from _private.priVariable"
myClassInstance.priMethod(); //Throws an Error
