Getting form values with looped name insertions from the DOM?

[Brian A]

Let's say I have, in a form, the name 'firstName' .
eg. <input type="text" name="firstName" />
When the form is submitted I can get a value for this with syntax:-
fn=form.firstName.value;
This works. 'fn' gives the value of 'firstName', so no problem there.

However, it means that for every name in the form I have
to include a similar statement. I want to put this in a loop and feed
in different names. I can get them from the DOM.

Clearly it obviously isn't possible to do the following, though it
illustrates what I want to do.
x=firstName;
fn=form.x.value;
(where x replaces 'firstName')
So what method can I use?

Why do people keep trying to use XHTML on the web?

"When the form is submitted"? Are you working on the server or the client? Client.

Assuming you are referring to client side, you use the elements collection:

form.elements[x].value

Thank you!!
That solves my problem.
