Is there a simple way, through the use of the onclick event, to show and hide text? I don't want to use a <div> unless completely necessary.
Basically I have a form, and it contains username and password text fields, depending on which <radio> button is hit, the username/password fields will be disabled (already coded that part) and I also want the red * next to these fields to disappear, so the user further realizes that the username/password fields don't need to be filled in.

Is there a quick way to do this with the onclick() event in javascript?

I know, I know...I really need to learn javascript already
