adding an object into another object that is in another object

Question

Say that there are three objects, a note, a noteState, and history:

var note = {
    text: "hello new world"
}

var history = {}
var noteState = {}

how would i be able to add note into noteState, and then add noteState into history?

could i potentially do something like:

$.extend(noteState, {"note1": note});
$.extend(history, {"noteState1": noteState});

and if I were to refer back to it to grab the text from note, how would i go about doing so?

history.noteState1.note1.text  // ?

or is there another method to go about this? thank you!

Answer 1

Why don't you simply

var note = {
    text: "hello new world"
}

var history = {}
var noteState = {}

noteState.note = note;
history.noteState= noteState;
alert(history.noteState.note.text);//alerts hello new world

Answer 2

Yes, you can do that and you don't have to use extend, simply set the properties. You don't even have to use distinct names, so following will do just fine :

noteState.note = note;
history.noteState = noteState;

Then, just as you wrote, you could use

 history.noteState.note.text

to retrieve the nested properties.

我想你也可以使用prototype属性来链接你的对象
