Does any one have a reference site that shows how to show/hide a textfield after a radio button has been selected? I have two radio buttons, and when a visitor selects yes, it shows, no it hides. This part of the script for me works except for the fact that its inaccessible when JS is disabled.

Code:
function offcitizen(){
document.getElementById("hidethiscitizen").style.display = 'none';
}
function oncitizen() {
   document.getElementById("hidethiscitizen").style.display = '';
}
Followed by this on the table row:

Code:
<tr id="hidethiscitizen">
And the appropriate onclick behavior for the radio button. Anyone know of a solution to make this accessible when JS is disabled?
