Javascript - Function Variable to use in another variable

I want to use a function's variable value to build a variable in the function.

Here's what I got so far:

function foo(1a, 1b) {
 var money = document.myform.1b;
}

So basically, if I pass in foo(aaa, bbb), I would like the variable money to be:

var money = document.myform.bbb;

You can use document.myform[bbb] if bbb is a string. Which effect are you after?

1

var bbb="variablename";
var money = document.myform.bbb

or 2

var bbb="variablename";
var money=document.myform.variablename

function foo(a, b) {
  var money = document.myform[b];
}

Also, I don't believe js vars can begin with a number.
