How to make a private static array in a javascript class?

I want to make a static array in a javascript class, for this I do:
var Manager = (function () {
function Manager() {
var ubications = new ArrayList();
this.ubicationsArray = function () {
return(ubication);
};
}
Manager.prototype.addUbication = function (ubication) {
Manager.ubicationsArray().add(ubication);
};
Manager.prototype.getUbication = function (index) {
return Manager.ubicationsArray().get(index);
};
Manager.prototype.sizeOfUbications = function () {
return Manager.ubicationsArray().size();
};
return Manager;
}());
Manager["__class"] = "Manager";
Where ubications is the static array and the function ubicationsArray is the public function to acces the array.
I try to use this code with:
var ubication = new Ubication(123,456);
var manager = new Manager();
manager.addUbication(ubication);
alert(manager.sizeOfUbications());
But I got this error:
Uncaught TypeError: Manager.ubicationsArray is not a function
How is the correct way to use static arrays in a javascript code?

Currently, JavaScript can only do privacy with respect to function scope.
function Manager () {
}
Manager.prototype = (function (){
var ubications = [];
return {
addUbication: function (u) {
ubications.push(u);
},
getUbication: function (index) {
return ubications[index];
},
sizeOfUbications: function () {
return ubications.length;
}
};
})();

Inside your constructor function, this.ubicationsArray assigns a property to the instance of the object, not the constructor itself.
Perhaps you want something like this:
function Manager() {
}
var ubications = new ArrayList();
Manager.ubicationsArray = function () {
return(ubication);
};
Note that this property isn't really "private". This would be more-private:
var Manager = (function () {
function Manager() {
}
var ubications = new ArrayList();
Manager.prototype.addUbication = function (ubication) {
ubications.add(ubication);
};
Manager.prototype.getUbication = function (index) {
return ubications.get(index);
};
Manager.prototype.sizeOfUbications = function () {
return ubications.size();
};
return Manager;
}());
Manager["__class"] = "Manager";

Passing references of a class to another class and using its methods

Let's say you're making a game. You want to try and not pollute the global scope and possibly limit the user's ability to easily alter the game (doubtful with client-side). You feel like modules might be unnecessary for your purposes. Is it bad practice to pass references to a class to another class during instantiation to access its methods?
Contrived example:
//game.js
var Game = (function () {
function Game() {
this.currentLevel = null;
this.score = 0;
}
Game.prototype.addScore = function (num) {
this.score += num;
};
Game.prototype.goToLevel = function (diff) {
this.currentLevel = new Level(this, diff);
};
Game.prototype.returnHome = function (level) {
this.currentLevel = null;
};
return Game;
})();
//level.js
var Level = (function () {
function Level(game, difficulty) {
this.game = game; //reference to game
this.difficulty = difficulty;
this.entities = [];
this.load();
}
Level.prototype.load = function () {
this.addEntity({name: 'tim', power: 23, difficulty: this.difficulty});
};
Level.prototype.leave = function () {
this.game.returnHome();
};
Level.prototype.addEntity = function (options) {
this.entities.push(new Entity(this, options));
};
Level.prototype.removeEntity = function (entity) {
for(var x = 0; x < this.entities.length; x++) {
if(this.entities[x] === entity) this.entities.splice(x, 1);
}
};
return Level;
})();
//level.js
var Entity = (function () {
function Entity(level, options) {
this.level = level; //reference to level
this.options = options;
}
Entity.prototype.kill = function () {
this.level.removeEntity(this); // anti-pattern?
this.level.game.addScore(34.53); // too closely coupled?
};
return Entity;
})();
//main.js
var Main;
(function (Main) {
var game = null;
function documentIsReady() {
start(); // Start the game
}
function start() {
game = new Game();
game.goToLevel('hard');
}
return {
documentIsReady: documentIsReady
}
})(Main || (Main = {}));
$(document).ready(function () {
Main.documentIsReady();
});
Forgive the half-baked example. If you end up with many instances of the 'Entity' class, do all the references to 'Level', though the same instance, start taking more memory? Are there other pitfalls? Another method would be to implement some kind of interface that you can access that allow classes to talk to each other.

A prototype-less, new-less, one-instance-only javascript object?

This doesn't work.
var genericClickHandler = function () {
this.handlers = [];
if (console && console.log) {
console.log("this:", this);
console.log("event:", event);
}
};
genericClickHandler.addHandler = function (handlerSpec) {
this.handlers.push(handlerSpec);
return this;
};
genericClickHandler.executeHandler = function (handlerName) {
for (var i = 0; i < this.handlers.length; i++) {
if (handlerName === this.handlers[i][0]) {
this.handlers[i][1]();
}
}
return this;
};
It doesn't work because the addHandler can't see the this.handlers in genericClickHandler.
Anyway what I'm after is function that gets defined once, but has methods and properties. I want to be able to use the function with Google Maps like this:
heatmap.addListener("click", genericClickHandler)
circle.addListener("click", genericClickHandler)
polygons.addListener("click", genericClickHandler)
So in the first instance, it only reports the this and event object. However, I then want to write code which extends the genericClickHandler dynamically so that it can implement map-object-specific behaviour.

Here's an example of what I meant using an object rather than a function.
var genericClickHandler = {
handlers: []
};
genericClickHandler.addHandler = function (name, fn) {
this.handlers.push([name, fn]);
return this;
};
genericClickHandler.executeHandler = function (name) {
for (var i = 0, l = this.handlers.length; i < l; i++) {
if (this.handlers[i][0] === name) this.handlers[i][1]();
}
};
genericClickHandler.addHandler('click', function () {
console.log('hi');
});
genericClickHandler.addHandler('click', function () {
console.log('hallo again');
});
genericClickHandler.executeHandler('click'); // hi... hallo again
DEMO

if you want to create an object, here you can see 2 ways to do the same thing, javascript got multiple way to write the same things.
var genericClickHandler = function()
{
this.handlers = [];
this.addHandler = function (handlerSpec)
{
this.handlers.push(handlerSpec);
return this;
},
this.executeHandler = function (handlerName)
{
this.handlers[handlerName]();
return this;
}
};
//sample:
var tmp = new genericClickHandler();
console.log(tmp.handlers);
console.log(tmp.addHandler("TEST"));
Another way to write the same object, but more optimised : prototype will be stored once for each object
var genericClickHandler = function(){}
genericClickHandler.prototype =
{
handlers:[],
addHandler : function (handlerSpec)
{
this.handlers.push(handlerSpec);
return this;
},
executeHandler : function (handlerName)
{
this.handlers[handlerName]();
return this;
}
}
//sample:
var tmp = new genericClickHandler();
console.log(tmp.handlers);
console.log(tmp.addHandler("TEST"));

How to create a class which has a property and a function with same name

I want to be able to call simultaneously something like this in javascript:
classInstance.room.get('criteria');
classInstance.room('criteria').remove('criteria');
classInstance.room().update('criteria');
I have seen implemented something similar at shouldjs
should(10).be.a.Number();
(10).should.be.a.Number();
Updated
I have the following code:
function connectToDatabase() {
var server = orientDB(dbConfig.server);
var db = server.use(dbConfig.database);
db.on("endQuery", function onDbEndQuery() {
db.server.close();
});
return db;
}
var DbSet = function DbSet(name) {
return {
list: function list(where, select, order) {
where = where || true;
select = _.isString(select) || _.isArray(select) ? select : '*';
order = _.isString(order) || _.isArray(order) ? order : 'rid';
return connectToDatabase()
.select(select)
.from(name)
.where(where)
.order(order)
.all();
},
get: function get(where, select) {
where = where || true;
select = _.isString(select) || _.isArray(select) ? select : '*';
return connectToDatabase()
.select(select)
.from(name)
.where(where)
.all()
.then(function onResults(results) {
if (results.length > 1) {
throw new Error('multiple results');
}
return results[0];
});
},
create: function create(record) {
return connectToDatabase()
.insert()
.into(name)
.set(record)
.one();
},
update: function update(where, changes) {
where = where || true;
return connectToDatabase()
.update(name)
.set(changes)
.where(where)
.scalar();
},
remove: function remove(where) {
where = where || true;
return connectToDatabase()
.delete('VERTEX', name)
.where(where)
.scalar();
}
};
};
var db = function getDb() {
return {
room: new DbSet('Room'),
invitation: new DbSet('Invitation'),
participant: new DbSet('Participant'),
};
};
module.exports = db();
And I want to change the code be able to execute the following code:
var db=require('path/to/database');
var room = db.room.get({name:'room 1'});
var sameRoom = db.room({name:'room 1'}).get();
db.room.create({name:'second room'});
db.room({name:'second room'}).create();
//same for methods list and delete
var room = db.room.list({status:'active'});
var sameRooms = db.room({status:'active'}).list();
db.room.update({name:'second room'},{status:'inactive'});
db.room({name:'second room'}).update({status:'inactive'});
I want to be able to execute the same code for Invitation and Participant too.

We need more information as to what those functions do, but this code presents those features.
Klass = function () {};
Klass.prototype.room = function () {
....
return {
get: function () {...},
remove: function () {...},
update: function () {...}
}
};
Klass.prototype.room.get = function () {...};
classInstance = new Klass();

How to get dynamic HTML and Javascript values from a page using PhantomJS

How can I get the latest page data (HTML & Javascript varaibles) from PhantomJS
e.g page.refresh() or something?
I have an Interval, than checks a variable (on the page) every 200ms. However, this variable and the page content, isn't shown to have changed over time. (even though I know it has)
So I need an efficient way to check the value of a JS variable every 200ms or so,
then once I've discovered that variable has changed value, I want to request the latest page HTML.
How can I do this?
var Error = function (description) {
this.description = description;

this.status = status;
this.content = content;
this.error = error;
return this;
};
function outputAndExit(dto) {
console.log(JSON.stringify(dto));
phantom.exit();
}
//For any uncaught exception, just log it out for .NET to capture
window.onerror = function (errorMsg, url, lineNumber) {
var description = 'window.onerror caught an error: ' +
'errorMsg: ' + errorMsg +
'url: ' + url +
'lineNumber: ' + lineNumber;
outputAndExit(new DTO(false, null, new Error(description)));
};

if (this.system.args.length == 0) {
outputAndExit(new DTO(false, null, new Error('No arguments given')));
}
//system.args[0] Was the name of this script
this.url = this.system.args[1];
};
this.updateIsContentReadyForCrawler = function () {
var updateIsContentReadyForCrawler = self.page.evaluate(function () {
self.isContentReadyForCrawler = window.isContentReadyForCrawler;
});
};
this.openPage = function () {
self.page.open(this.url, function (status) { //NB: status = 'success' || 'fail'
if (status !== 'success') {
outputAndExit(new DTO(false, null, new Error('page.open received a non-success status')));
}
self.initTicker();
});
};
this.initTicker = function () {
this.ticker = setInterval(self.handleTick, self.tickerInterval);
};
this.handleTick = function () {
self.tickerElapsed += self.tickerInterval;
self.updateIsContentReadyForCrawler();
if (self.isContentReadyForCrawler) {
clearInterval(self.ticker);
var content = self.page.content;
self.finish(true, content, null);
} else {
var tooMuchTimeElapsed = self.tickerElapsed > 7000;
if (tooMuchTimeElapsed) {
clearInterval(self.ticker);
self.finish(false, null, new Error('Too much time elapsed'));
}
}
};
this.finish = function (status, content, error) {
content = content || '';
error = error || {};
outputAndExit(new DTO(status, content, error));
};
};

I think you are almost there: you need to be using page.evaluate(), but currently only use it to get window.isContentReadyForCrawler. You need to use page.evaluate() to grab the latest HTML too.
I'm going to shamelessly paste in code from another answer (https://stackoverflow.com/a/12044474/841830):
var html = page.evaluate(function () {
var root = document.getElementsByTagName("html")[0];
var html = root ? root.outerHTML : document.body.innerHTML;
return html;
});
