This section extends the Level 1 Core API to describe objects and methods specific to HTML documents [HTML4.0]. 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 the HTML 4.0 DTDs.
More specifically, this document includes the following specializations for HTML:
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 1 does not include mechanisms to access and modify style specified through CSS 1. Furthermore, it does not define an event model for HTML documents. This functionality is planned to be specified in a future Level of this specification.
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" and the version is "1.0".
The interfaces in this specification are designed for HTML 4.0 documents, and not for XHTML documents. Use of the HTML DOM with XHTML documents may result in incorrect processing; see Appendix C11 in the [XHTML10] for more information.
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.
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 of type unsigned long, readonly
An HTMLDocument is the root of the HTML hierarchy and
holds the entire content. Besides 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);
};
URL of type DOMString, readonly
anchors of type HTMLCollection, readonlyA) elements in a document
with a value for the name attribute.Note. For reasons of backwards
compatibility, the returned set of anchors only contains those anchors created with the name
attribute, not those created with the id attribute.
applets of type HTMLCollection, readonlyOBJECT elements that include
applets and APPLET (deprecated) elements in
a document.
body of type HTMLElementBODY contents, returns the BODY
element. In frameset documents, this returns the outermost
FRAMESET element.
cookie of type DOMStringname=value;expires=date.
domain of type DOMString, readonly
forms of type HTMLCollection, readonly
images of type HTMLCollection, readonlyIMG elements in a document.
The behavior is limited to IMG elements for
backwards compatibility.

anchor (A) elements in a document
with a value for the href attribute.

writelnopen(). The text is parsed into the

HTML attributes are exposed as properties on the element object. The DOM naming conventions always determine the name of the exposed property, 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., (disabled)) | 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 namespace 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.
tagName)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 reserved for future usage.
interface HTMLElement : Element {
attribute DOMString id;
attribute DOMString title;
attribute DOMString lang;
attribute DOMString dir;
attribute DOMString className;

(or vice versa). See the LINK element definition in HTML 4.0.
