RadioNodeList: value property
If the underlying element collection contains radio buttons, the
RadioNodeList.value property represents the checked radio
button. On retrieving the value property, the value of the
currently checked radio button is returned as a string. If the collection
does not contain any radio buttons or none of the radio buttons in the collection is in
checked state, the empty string is returned. On setting the
value property, the first radio button input element whose
value property is equal to the new value will be set to
checked.
