2.1. Introduction

This section extends the Level 1 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:

to specialize and add functionality that relates specifically to HTML documents and elements.
to address issues of backwards compatibility with the "DOM Level 0".
to provide convenience mechanisms, where appropriate, for common and frequent operations on HTML documents.

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. For DOM Level 1, 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.

The W3C DOM Working Group attempted, wherever possible, to maintain compatibility with the "DOM Level 0", which refers to the functionality exposed in Netscape Navigator 3.0 and Microsoft Internet Explorer 3.0.

More specifically, this document includes the following specializations for HTML:

An HTMLDocument interface, derived from the core Document interface. HTMLDocument specifies the operations and queries that can be made on a HTML document.
An 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.
Specializations for all HTML elements that have attributes that extend beyond those specified in the 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.

2.2. HTML Application of Core DOM

2.2.1. Naming Conventions

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. Properties and Methods

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. Non-HTML 4.0 interfaces and attributes

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.

2.3. Miscellaneous Object Definitions

Interface HTMLCollection

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 live meaning that they are automatically updated when the underlying document is changed.

IDL Definition

interface HTMLCollection {
  readonly attribute  unsigned long        length;
  Node                      item(in unsigned long index);
  Node                      namedItem(in wstring name);
};

Attributes

length: This attribute specifies the length or size of the list.

Methods

item

This method retrieves a node specified by ordinal index. Nodes are numbered in tree order (depth-first traversal order).

Parameters

index

The index of the node to be fetched. The index origin is 0.

Return Values: The Node at the corresponding position upon success. A value of null is returned if the index is out of range.

This method raises no exceptions.

namedItem

This method retrieves a Node using a name.

Parameters

name

The name of the Node to be fetched.

Return Values: The Node with a name or id attribute whose value corresponds to the specified string. Upon failure (e.g., no Node with this name exists), returns null.

This method raises no exceptions.

2.4. Objects related to HTML documents

Interface HTMLDocument

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:

alinkColor
background
bgColor
fgColor
linkColor
vlinkColor

IDL Definition

interface HTMLDocument : Document {
           attribute  wstring              title;
  readonly attribute  wstring              referrer;
  readonly attribute  wstring              domain;
  readonly attribute  wstring              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  wstring              cookie;
  void                      open();
  void                      close();
  void                      write(in wstring text);
  void                      writeln(in wstring text);
  Element                   getElementById(in wstring elementId);
  NodeList                  getElementsByName(in wstring elementName);
};

Attributes

title: The title of a document as specified by the TITLE element in the head of the document.

referrer: Returns the URI of the page that linked to this page. The value is an empty string if the user navigated to the page directly (not through a link, but, for example, via a bookmark).

domain: The domain name of the server that served the document, or a null string if the server cannot be identified by a domain name.

URL: The complete URI of the document.

body: The element that contains the content for the document. In documents with BODY contents, returns the BODY element, and in frameset documents, this returns the outermost FRAMESET element.

images: A collection of all the IMG elements in a document. The behavior is limited to IMG elements for backwards compatibility.

applets: A collection of all the OBJECT elements that include applets and APPLET (deprecated) elements in a document.

links: A collection of all AREA elements and anchor (A) elements in a document with a value for the href attribute.

forms: A collection of all the forms of a document.

anchors: A collection of all the anchor (A) 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.

cookie: The cookies associated with this document. If there are none, the value is an empty string. Otherwise, the value is a string: a semicolon-delimited list of "name, value" pairs for all the cookies associated with the page. For example, name=value;expires=date.

Methods

open: Note. This method and the ones following allow a user to add to or replace the structure model of a document using strings of unparsed HTML. At the time of writing alternate methods for providing similar functionality for both HTML and XML documents were being considered. The following methods may be deprecated at some point in the future in favor of a more general-purpose mechanism.
Open a document stream for writing. If a document exists in the target, this method clears it.

This method has no parameters.
This method returns nothing.
This method raises no exceptions.

close: Closes a document stream opened by open() and forces rendering.

This method has no parameters.
This method returns nothing.
This method raises no exceptions.

write

Write a string of text to a document stream opened by open(). The text is parsed into the document's structure model.

Parameters

text

The string to be parsed into some structure in the document structure model.

This method returns nothing.
This method raises no exceptions.

writeln

Write a string of text followed by a newline character to a document stream opened by open(). The text is parsed into the document's structure model.

Parameters

text

The string to be parsed into some structure in the document structure model.

This method returns nothing.
This method raises no exceptions.

getElementById

Returns the Element whose id is given by elementId. If no such element exists, returns void. Behavior is not defined if more than one element has this id.

Parameters

elementId

The unique id value for an element.

Return Values

This method raises no exceptions.

getElementsByName

Returns the (possibly empty) collection of elements whose name value is given by elementName.

Parameters

elementName

The name attribute value for an element.

Return Values

This method raises no exceptions.

2.5. HTML Elements

2.5.1. Property Attributes

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 wstring

Value list (e.g., (left | right | center)) wstring

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.

2.5.2. Naming Exceptions

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.

2.5.3. Exposing Element Type Names (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".

2.5.4. The HTMLElement interface

Interface HTMLElement

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:

HEAD
special: SUB, SUP, SPAN, BDO
font: TT, I, B, U, S, STRIKE, BIG, SMALL
phrase: EM, STRONG, DFN, CODE, SAMP, KBD, VAR, CITE, ACRONYM, ABBR
list: DD, DT
NOFRAMES, NOSCRIPT
ADDRESS, CENTER

Note. The style attribute for this interface is reserved for future usage.
