Trying to understand how to objects within objects

[steven.harms]

Hi,

I. Multiple layers of dereferencing:

I took this example from Amy Hoy's javascript tutorial:

var foo = {
bar:"baz",
zort:"narf",
aNumber:5,
anArray:['banana','plaintain','ugli fruit'],
anotherObject: {
king: "hobo"
},
anotherObject2: {
king: "hobo2"
},
doStuff:function() {
alert("I'm doing stuff!")
}
}

When I do

alert(foo.bar) --> "baz" comes up. Great!

Now this works....

// This works
alert(foo.anotherObject.king)

But say i wanted to, based on input, return out of anotherObject or
anotherObject2.

var x="anotherObject"

alert(foo.x.king)

does not work.

Hrm. Is this multiple layer of dereferencing possible?

II. Is there a tutorial for 'intermediate' javascripters?

var x="anotherObject"
alert(foo.x.king)
does not work.

try foo[x].king

Tutorials abound. Good tutorials are rare.

The newsgroup FAQ is a great place to start, and take a look at
