CharacterData
interface extends Node with a set of attributes and methods for accessing character data in the DOM. For clarity this set is defined here rather than on each object that uses these attributes and methods. No DOM objects correspond directly toCharacterData
, thoughText
and others do inherit the interface from it. Alloffsets
in this interface start from0
. As explained in theDOMString
interface, text strings in the DOM are represented in UTF-16, i.e. as a sequence of 16-bit units. In the following, the term 16-bit units is used whenever necessary to indicate that indexing on CharacterData is done in 16-bit units. See also the Document Object Model (DOM) Level 2 Core Specification.
