The Comment interface represents textual notations within markup; although it is generally not visually shown, such comments are available to be read in the source view. Comments are represented in HTML and XML as content between '!--' and '--'. In XML, the character sequence '--' cannot be used within a comment.

Constructor

new (data:String = "")

Throws:

null

DOMError

Inherited Variables

Defined by CharacterData

data:String

Is a DOMString representing the textual data contained in this object.

read onlylength:Int

Returns an unsigned long representing the size of the string contained in CharacterData.data.

read onlynextElementSibling:Element

read onlypreviousElementSibling:Element

Defined by Node

read onlybaseURI:String

Returns a DOMString representing the base URL. The concept of base URL changes from one language to another; in HTML, it corresponds to the protocol, the domain name and the directory structure, that is all until the last '/'.

read onlychildNodes:NodeList

Returns a live NodeList containing all the children of this node. NodeList being live means that if the children of the Node change, the NodeList object is automatically updated.

read onlyfirstChild:Node

Returns a Node representing the first direct child node of the node, or null if the node has no child.

read onlylastChild:Node

Returns a Node representing the last direct child node of the node, or null if the node has no child.

read onlylocalName:String

Returns a DOMString representing the local part of the qualified name of an element.

Note: In Firefox 3.5 and earlier, the property upper-cases the local name for HTML elements (but not XHTML elements). In later versions, this does not happen, so the property is in lower case for both HTML and XHTML. 1.9.2

read onlynamespaceURI:String

The namespace URI of this node, or null if it is no namespace.

Note: In Firefox 3.5 and earlier, HTML elements are in no namespace. In later versions, HTML elements are in the https://www.w3.org/1999/xhtml/ namespace in both HTML and XML trees. 1.9.2

read onlynextSibling:Node

Returns a Node representing the next node in the tree, or null if there isn't such node.

read onlynodeName:String

Returns a DOMString containing the name of the Node. The structure of the name will differ with the name type. E.g. An HTMLElement will contain the name of the corresponding tag, like 'audio' for an HTMLAudioElement, a Text node will have the '#text' string, or a Document node will have the '#document' string.

read onlynodeType:Int

Returns an unsigned short representing the type of the node. Possible values are:

Name Value

ELEMENT_NODE 1
ATTRIBUTE_NODE (deprecated) 2
TEXT_NODE 3
CDATA_SECTION_NODE (deprecated) 4
ENTITY_REFERENCE_NODE (deprecated) 5
ENTITY_NODE (deprecated) 6
PROCESSING_INSTRUCTION_NODE 7
COMMENT_NODE 8
DOCUMENT_NODE 9
DOCUMENT_TYPE_NODE 10
DOCUMENT_FRAGMENT_NODE 11
NOTATION_NODE (deprecated) 12

nodeValue:String

Returns / Sets the value of the current node

read onlyownerDocument:HTMLDocument

Returns the Document that this node belongs to. If no document is associated with it, returns null.

read onlyparentElement:Element

Returns an Element that is the parent of this node. If the node has no parent, or if that parent is not an Element, this property returns null.

read onlyparentNode:Node

Returns a Node that is the parent of this node. If there is no such node, like if this node is the top of the tree or if doesn't participate in a tree, this property returns null.

read onlyprefix:String

Is a DOMString representing the namespace prefix of the node, or null if no prefix is specified.

read onlypreviousSibling:Node

Returns a Node representing the previous node in the tree, or null if there isn't such node.

textContent:String

Returns / Sets the textual content of an element and all its descendants.
