Is a radio Radio Box checked?

[MattMattMatt]

How do I tell if a radio box is checked?
is there something like
document.q1.b.checkidity?

Or, is there a way to find out which radio box is ticked in a form?

Thanks for anyhelp.

You can check it like this..

myForm.myRadioButton.checked


Example:

if (myForm.myRadioButton.checked !== true)
{
alert("Hey! You didn\'t make a selection!")
}



Happy coding, :)...

Thanks very much, but I am still a bit stuck.

I need to add one to the score (yes, i am doing a quiz), only if a particular box is selected.

Your piece of code asks if all the boxes in the form are ticked, rather than if a particular box is ticked.

I can't give each option a seperate name (and then ask if it is ticked) because if the names are different, all the boxes can be ticked.

I think I've got it working now. Thanks.
