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
.
