Getting Values From Form Elements Using Prototype
Retrieving a value for a radio field:
try {
val = Form.getInputs('form_name', 'radio', 'group_name').find(function(radio) { return radio.checked; }).value;
} catch(e) { val = ''; }
Retrieving all values from a group of checkboxes:
Form.getInputs('form_name', 'checkbox', 'group_name').each(function(e) {
if ($(item).checked) {
v = (v == '') ? $(item).value : v + ', ' + $(item).value;
t = t + 7;
}
});
