The CharacterData
abstract interface represents a Node
object that contains characters. This is an abstract interface, meaning there aren't any object of type CharacterData
: it is implemented by other interfaces, like Text
, Comment
, or ProcessingInstruction
which aren't abstract.
Properties
Inherits properties from its parent, Node
, and implements the ChildNode
and NonDocumentTypeChildNode
interface.
CharacterData.data
- Is a
DOMString
representing the textual data contained in this object. CharacterData.length
Read only- Returns an
unsigned long
representing the size of the string contained inCharacterData.data
. NonDocumentTypeChildNode.nextElementSibling
Read only- Returns the
Element
immediately following the specified one in its parent's children list, ornull
if the specified element is the last one in the list. NonDocumentTypeChildNode.previousElementSibling
Read only- Returns the
Element
immediately prior to the specified one in its parent's children list, ornull
if the specified element is the first one in the list.
Methods
Inherits methods from its parent, Node
, and implements the ChildNode
and NonDocumentTypeChildNode
interface.
CharacterData.appendData()
- Appends the given
DOMString
to theCharacterData.data
string; when this method returns,data
contains the concatenatedDOMString
. CharacterData.deleteData()
- Removes the specified amount of characters, starting at the specified offset, from the
CharacterData.data
string; when this method returns,data
contains the shortenedDOMString
. CharacterData.insertData()
- Inserts the specified characters, at the specified offset, in the
CharacterData.data
string; when this method returns,data
contains the modifiedDOMString
. ChildNode.remove()
- Removes the object from its parent children list.
CharacterData.replaceData()
- Replaces the specified amount of characters, starting at the specified offset, with the specified
DOMString
; when this method returns,data
contains the modifiedDOMString
. CharacterData.substringData()
- Returns a
DOMString
containing the part ofCharacterData.data
of the specified length and starting at the specified offset.
