An HTMLCollection
is a list of nodes. An individual node may
be accessed by either ordinal index or the node'sname
or
id
attributes. Note: Collections in the HTML DOM are assumed
to be live meaning that they are automatically updated when the
underlying document is changed.
See also the Document Object Model (DOM) Level 2 Specification.
