This section extends the Core API to describe objects and methods specific to HTML documents. In general, the functionality needed to manipulate hierarchical document structures, elements, and attributes will be found in the core section; functionality that depends on the specific elements defined in HTML will be found in this section.
The goals of the HTML-specific DOM API are:
The key differences between the core DOM and the HTML application of DOM is that the HTML Document Object Model exposes a number of convenience methods and properties that are consistent with the existing models and are more appropriate to script writers. In many cases, these enhancements are not applicable to a general DOM because they rely on the presence of a predefined DTD. The transitional and frameset DTDs for HTML 4.0 are assumed. Interoperability between implementations is only guaranteed for elements and attributes that are specified in these DTDs.
More specifically, this document includes the following specializations for HTML:
HTMLDocument
interface, derived from the core
Document
interface. HTMLDocument
specifies the operations and queries that can be made on a HTML
document.HTMLElement
interface, derived from the core
Element
interface. HTMLElement
specifies
the operations and queries that can be made on any HTML
element. Methods on HTMLElement
include those that
allow for the retrieval and modification of attributes that apply
to all HTML elements.HTMLElement
interface. For all such attributes, the derived interface for the
element contains explicit methods for setting and getting the
values.The DOM Level 2 includes mechanisms to access and modify style specified through CSS and defines an event model that can be used with HTML documents.
The interfaces found within this section are not mandatory. A DOM
application can use the hasFeature
method of the
DOMImplementation
interface to determine whether they
are supported or not. The feature string for all the interfaces listed in
this section is "HTML".
The HTML DOM follows a naming convention for properties, methods, events, collections, and data types. All names are defined as one or more English words concatenated together to form a single string.
The property or method name starts with the initial keyword in lowercase, and each subsequent word starts with a capital letter. For example, a property that returns document meta information such as the date the file was created might be named "fileDateCreated". In the ECMAScript binding, properties are exposed as properties of a given object. In Java, properties are exposed with get and set methods.
While most of the interfaces defined below can be mapped directly to elements defined in the HTML 4.0 Recommendation, some of them cannot. Similarly, not all attributes listed below have counterparts in the HTML 4.0 specification (and some do, but have been renamed to avoid conflicts with scripting languages). Interfaces and attribute definitions that have links to the HTML 4.0 specification have corresponding element and attribute definitions there; all others are added by this specification, either for convenience or backwards compatibility with DOM Level 0 implementations.
The HTMLDOMImplementation
interface extends the
DOMImplementation
interface with a method for creating an
HTML document instance.
// Introduced in DOM Level 2: interface HTMLDOMImplementation : DOMImplementation { HTMLDocument createHTMLDocument(in DOMString title); };
createHTMLDocument
HTMLDocument
object with the minimal tree
made of the following elements: HTML
, HEAD
,
TITLE
, and BODY
.
A new |
An HTMLCollection
is a list of nodes. An individual node
may be accessed by either ordinal index or the node's
name
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.
interface HTMLCollection { readonly attribute unsigned long length; Node item(in unsigned long index); Node namedItem(in DOMString name); };
length

, readonly
An HTMLDocument
is the root of the HTML hierarchy and
holds the entire content. Beside providing access to the hierarchy, it
also provides some convenience methods for accessing certain sets of
information from the document.
The following properties have been deprecated in favor of the corresponding ones for the BODY element:
interface HTMLDocument : Document { attribute DOMString title; readonly attribute DOMString referrer; readonly attribute DOMString domain; readonly attribute DOMString URL; attribute HTMLElement body; readonly attribute HTMLCollection images; readonly attribute HTMLCollection applets; readonly attribute HTMLCollection links; readonly attribute HTMLCollection forms; readonly attribute HTMLCollection anchors; attribute DOMString cookie; void open(); void close(); void write(in DOMString text); void writeln(in DOMString text); Element getElementById(in DOMString elementId); NodeList getElementsByName(in DOMString elementName); };

getElementsByName
HTML attributes are exposed as properties on the element object. The name of the exposed property always uses the naming conventions, and is independent of the case of the attribute in the source document. The data type of the property is determined by the type of the attribute as determined by the HTML 4.0 transitional and frameset DTDs. The attributes have the semantics (including case-sensitivity) given in the HTML 4.0 specification.
The attributes are exposed as properties for compatibility
with DOM Level 0. This usage
is deprecated because it can not be generalized to all possible
attribute names, as is required both for XML and potentially for future
versions of HTML. We recommend the use of generic methods on the core
Element
interface for setting, getting and removing
attributes.
DTD Data Type | Object Model Data Type |
CDATA | DOMString |
Value list (e.g., (left | right | center)) | DOMString |
one-value Value list (e.g., (border)) | boolean |
Number | long int |
The return value of an attribute that has a data type that is a
value list is always capitalized, independent of the case of
the value in the source document. For example, if the value of
the align attribute on a P element is "left" then it is
returned as "Left". For attributes with the CDATA
data type, the case of the return value is that given in
the source document.
To avoid name-space conflicts, an attribute with the same
name as a keyword in one of our chosen binding languages is
prefixed. For HTML, the prefix used is "html".
For example, the for
attribute of the
LABEL
element
collides with loop construct naming conventions and is renamed
htmlFor
.
The element type names exposed through a property are in uppercase. For example, the body element type name is exposed through the "tagName" property as "BODY".
All HTML element interfaces derive from this class. Elements that only
expose the HTML core attributes are represented by the base
HTMLElement
interface. These elements are as follows:
Note. The style
attribute for this interface is
part of the Document Object Model CSS. See the HTMLElementCSS
interface.
interface HTMLElement : Element { attribute DOMString id; attribute DOMString title; attribute DOMString lang; attribute DOMString dir; attribute DOMString className; };

resource, and defines this document's relationship to that resource
(or vice versa). See the LINK element definition in HTML 4.0.

The create* and delete* methods on the table allow authors to construct
and modify tables. HTML 4.0 specifies that only one of each of the
CAPTION

elements may exist in a table. Therefore, if one exists, and the
createTHead() or createTFoot() method is called, the method returns
the existing THead or TFoot element. See the TABLE element definition in HTML 4.0.
