Revision Content

 

HTMLOptionsCollection is an interface representing a collection of HTML option elements (in document order) and offers methods and properties for traversing the list as well as optionally altering its items.

Properties

  • length - As optionally allowed by the spec, Mozilla allows this property to be set, either removing options at the end when using a shorter length, or adding blank options at the end when setting a longer length. Other implementations could potentially throw a DOMException.

Methods

  • item(index) - returns the specific node at the given zero-based index (gives null if out of range)
  • namedItem(name) - returns the specific node with the given DOMString (i.e., string) id. Returns null if no such named node exists.
