I'd like to know the codes for the following problem.
Suppose, In a webpage, there is a question and four options (using radio
buttons) which users can choose. I want to know the codes to provide a few
lines after, say, the first option when users select the first option. When
other options were chosen, the lines should not be shown.
What should i design for that? Do any one know some Javascipt or Dhtml to do
that?
thanks, |
