Properties

The RadioNodeList interface inherits the properties of NodeList.

RadioNodeList.value

If the underlying element collection contains radio buttons, the 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.

Methods

The RadioNodeList interface inherits the methods of NodeList.
