pulling an array entry and using it

[wallabee]

seems hard to explain right now.

what i'm trying to do, as the title says, is pull an array entry and use it for the title of an array.

i have three arrays. one parent array that holds the names of the two child arrays.

var masterArray = new Array("squirrels", "chipmunks");
var squirrels = new Array;
squirrels["brown"] = 2;
squirrels["white"] = 6;
var chipmunks = new Array;
chipmunks["striped"] = 15;
chipmunks["spotted"] = 12;


my issue is this: by using a for loop, i can get "squirrels" and "chipmunks" to show up.

j = masterArray.length;
for (i=0; i<j; i++){
k = masterArray[i];
alert(k);
}


however, how do i take the resulting string "squirrels" and "chipmunks", and use them as the names of their own arrays so I can get to the numbers 2, 6, 15, or 12? i'd think like this:

function costCalc(location){
j = masterArray.length;
for (i=0; i<j; i++){
k = masterArray[i];
x = k.length;
for (i=0; i<x; i++){
alert(k[i])
}
}
}

this, apparently, isn't the right way? basically, i want k to turn into a string, so that when javascript sees "k[i]", it sees "chipmunk[i]" and not "masterArray[i][i]", so how do i do this? is the only answer nested arrays? do they even exist?

I thin what you want is Two Dimensional arrays. Here is a link to a tutorial on the subject:
