Object within and Object?

bunzu · 07-29-2012, 02:27 AM

Hey Guys,

I need a little help and I'm a bit confused. Here is the result that I want:

Code:

loggedObject2 = { 
	'0': { 'items': 'marble', 'quantity': 5 },
	'1': { 'items': 'rock', 'quantity': 3 } 
};

The problem I'm having right now is sticking an object into an object. I can get a part of it but not the other part.

Code:

loggedObject = {};

function logToObject(items,quantity){
	loggedObject.items = items;
	loggedObject.quantity = quantity
}
logToObject('marble', 5);
console.log(loggedObject);

Any help would be great!
Thanks!

Why not array ? since you still index them by number.

Code:

loggedObject = [];

loggedObject.push( { items:'marble', quantity:5} );
loggedObject.push( { items:'rock', quantity:3 } );

console.log(loggedObject);

If you want some OOP.

Code:

loggedObject = [];

function Material(Name, Quantity) { this.items = Name; this.quantity = Quantity ; }

loggedObject.push( new Material('marble' , 5) );
loggedObject.push( new Material('rock', 3) );

console.log(loggedObject);

It's just so I can learn more about objects. Maybe eventually I'll categorize it similar to:

Depending on what type of fruit/vegetable it is

Code:

loggedObject2 = { 
	'Vegetable': { 'items': 'Carrots', 'quantity': 5 },
	'Fruit': { 'items': 'Apple', 'quantity': 3, 'items': 'Banana', 'quantity': 3 } 
};

In that case just put the name you want in to object directly

Code:

loggedObject2 = {};

loggedObject2['Vegetable'] = { 'items': 'Carrots', 'quantity': 5 };
//or	
loggedObject2.Fruit = [{ 'items': 'Apple', 'quantity': 3 }, { 'items': 'Banana', 'quantity': 3 } ];

{ 'items': 'Apple', 'quantity': 3, 'items': 'Banana', 'quantity': 3 } is error, you can't do that and usualy items mean array of item, in this case you don't need it.

I write a long version but it easier to understand.

Code:

loggedObject2 = {};

loggedObject2.Vegetable = {};
loggedObject2.Vegetable.Carrot = {};
loggedObject2.Vegetable.Carrot.quantity = 5;

loggedObject2.Fruit = {};
loggedObject2.Fruit.Apple = {};
loggedObject2.Fruit.Apple.quantity = 3;

loggedObject2.Fruit.Banana = {};
loggedObject2.Fruit.Banana.quantity = 3;

ps. what you do isn't object, it's call Json

Code:

//Json  
{ 'items': 'Apple' }

//Object
{ items: 'Apple' }

Ahh. I guess I'm trying to write function that stores JSON data? I think that's what it's called.

Thanks by the way!
