JavaScript Object Notation

Is it possible to have something like the following so that 'three'
can access 'one':

var x = {
one: 1,
two: { three:this.one } // Or parent.one ?
}

If not (which I have nearly come to a conclusion on) what is the next
best way to accomplish this?

Functions have a this keyword whose value is set by the calling
function when the function is called, plain object don't have a this
property. You can use:

two: { three: x.one }

Really? I always get "x has no properties."

I didn't say it worked... :-x

I guess the closest is:

var x = { one: 1 };
x.two = { three: x.one};
alert( x.two.three );

Oh! Hehe. ;)

I guess the closest is:

var x = { one: 1 };
x.two = { three: x.one};
alert( x.two.three );

Thanks RobG.

Gecko has two beautiful methods - getter and setter.

var x = {
one: 1,
get two() {
return this.one + 1;
}
}
