I have a single radio button element (which is passed in via an Observer) and I want to detect if ANY of the radio buttons in it''s group are checked. How can I query all the radio buttons on the page in it''s group with just the element? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

// all radio input elements that are of the same name ("radioName")
$$(''input[type=radio][name=''+ radioName
+'']'');
// same as above, but also "checked"
$$(''input[type=radio][name=''+ radioName
+'']:checked'');
// are any checked?
!!$$(''input[type=radio][name=''+ radioName
+'']:checked'').length;
// or
$$(''input[type=radio][name=''+ radioName
+'']'').any(function(el) {
return el.checked;
})
