The simplest approach is to associate an onclick event handler with the 
checkbox element, e.g. <input type=checkbox onclick="toggle()" ...>, 
with toggle() defined as a function that processes the elements 
suitably. For the processing part, jQuery would make the code shorter 
and simpler than using a loop in pure JavaScript.

The details depend on many things. Can the elements in question be 
distinguisher e.g. by a class attribute, or in some other simpler way? 
What exactly does "disable" mean? Something like a disabled input box 
(visible but grayed out and not clickable, not contributing to form 
data)? Or empty space where the element appears when "enabled"? Or 
complete absence, causing a redraw of the page on every "disable" and 
"enable"?
