function Registry() {
var _data = {}
var that = this; // scope resolution for chaining
this.set = function (key, value) {
_data[key] = value;
return that; // returns our Registry object
};
this.get = function (key) {
return _data[key];
};
}

Now, you could instantiate a new Registry:
var reg = new Registry();

reg._data // undefined

reg.set("userIsAuthorized", false); // returns reg, so we could chain with other commands

reg.get("userIsAuthorized") // false

reg._data // undefined

If we view reg, _data will not be seen, and is therefore a "private" variable in the JavaScript class. ]]> http://www.phpdevblog.net/2009/09/oop-in-javascript-part-2-static-classes-and-singleton.html#comment4742 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-2-static-classes-and-singleton.html#comment4742 Matthew Maxwell Tue, 15 Sep 2009 16:04:48 +0000 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-2-static-classes-and-singleton.html#comment4773 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-2-static-classes-and-singleton.html#comment4773 Dominik Jungowski Wed, 16 Sep 2009 16:11:10 +0000 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-2-static-classes-and-singleton.html#comment12726 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-2-static-classes-and-singleton.html#comment12726 Cell phone batteries wholesale Sun, 28 Mar 2010 06:42:56 +0000
