Automatically select specific checkboxes on clicking a radio button

[leifstarkey]

Hi all...

My problem is I'm trying to make a form containing radio buttons and checkboxes. But on the event that one of the radio buttons is selected i want specific checkboxes to then be automatically selected.

E.g.
"On the event that gender male (radiobutton) is selected - for the form to then automatically select the following film genre (checkboxes) Action, Sci-Fi and Crime and leave unselected the remaining checkboxes."

Gender: >Male >Female


Film Genres:
Action[ / ] Romance[ ] Sci-Fi[ / ]
Musical[ ] Crime[ / ] Disney[ ]



If anyone can suggest how i would go about achiveing this; i would be truely grateful.

Unfortunately you've posted in the 'feedback' forum.
You might want to try the javascript forum :P

Call a function onclick (radio buttons) which checks the checkboxes, e.g.
[code=javascript]var checkboxes = document.getEle mentsByName(che ckboxesName);
for (i=0; i < checkboxes.leng th; i++) {
if (checkboxes[i].value == "Sci-Fi") checkboxes[i].checked = true;
...
}[/code]
