# Interface HTMLDocument

All Superinterfaces:
  `Document`, `Node`

public interface HTMLDocument extends Document
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: alinkColor background bgColor fgColor linkColor vlinkColor In DOM Level 2, the method `getElementById` is inherited from the `Document` interface where it was moved.

See also the Document Object Model (DOM) Level 2 Specification.

Since:
  1.4, DOM Level 2

## Method Details

### getTitle

String getTitle()
The title of a document as specified by the `TITLE` element in the head of the document.

### setTitle

void setTitle(String title)

### getReferrer

String getReferrer()
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).

### getDomain

String getDomain()
The domain name of the server that served the document, or `null` if the server cannot be identified by a domain name.

### getURL

String getURL()
The complete URI of the document.

### getBody

HTMLElement getBody()
The element that contains the content for the document. In documents with `BODY` contents, returns the `BODY` element. In frameset documents, this returns the outermost `FRAMESET` element.

### setBody

void setBody(HTMLElement body)

### getImages

HTMLCollection getImages()
A collection of all the `IMG` elements in a document. The behavior is limited to `IMG` elements for backwards compatibility.

### getApplets

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

### getLinks

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

### getForms

HTMLCollection getForms()
A collection of all the forms of a document.

### getAnchors

HTMLCollection getAnchors()
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.

### getCookie

String getCookie()
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` .

### setCookie

void setCookie(String cookie)

### open

void 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.

### close

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

### write

void write(String text)
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.

### writeln

void writeln(String text)
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.

### getElementsByName

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

Parameters:
  `elementName` - The `name` attribute value for an element.
Returns:
  The matching elements.
