Is it possible to hide a field if a particular word is entered into a field?

I have made a form where people can order brochures, but if a particular agent wants to order something I would like to hide the fields for particular brochures they cannot order as they have their own version.  Is it possible?

Hiding and showing form fields using JavaScript by Thom Parker has an example. you will need to deal with matched and unmatched names.
