document.myform.code + name ???

[Sean Berry]

Hopefully this is an easy question for some of you... I am new to JS.

I have a document with a lot of different select menus with names like
code1, code2, code3... etc
I have a function that does some autoselecting based on your current
selection....

function selectFromCode(name) {

give the above as the constructor... how do I get the following to work???
var codename = "document.myform.code" + name;

For example, I want codename to be a reference to document.myform.code3 if I
call the function using selectFromCode("3") or selectFromCode(3)

But I cannot get this to work...

Help is greatly appreciated.

Thanks for the links Mike... very informative....

var codename = document.myform["code" + name];

Works like a charm

document.forms['formName'].elements['elementName' + somethingElse];
