Manage FORM SELECT with multiple selections

[Stian]

Hi!

I have made a form with two SELECT LIST-boxes where the first is dynmically
filled when you enter the page, and then one can select multiple options
from the list and move across to the other box using javascript. Every
option in the list has an integer value.

The FORM is submitted with the POST method and received on an ASP page. I
then want to manage the selected options one by one. How can I separate
them?

It currently looks like this (with four selections from the box).
1, 5, 9, 10

I tried to manage this as a string, but was told that it was not a string.
Type mismatch: '[string: "1, 5, 9, 10"]'

Can anyone help med with some code that can separate these options for
further work?

Regards, Stian

And what happens when JavaScript code is not executed?

Well, just deal with it.

That's an ASP problem then. Try asking in an ASP group, and give a hint
about what you are actually doing, by revealing a piece of code. Posting
the URL wouldn't hurt either.

But regarding user interfaces, multiple selections in <select> menus
are generally awkward, inferior to sets of checkboxes. At least you
should specify a SIZE parameter value that equals the number of options.

Trivial in most programming languages - what is your preferred flavour?
