Properties

Anchor
inherits properties from HTMLElement and defines or overrides the
following:

name

Contains the name of an Anchor object.
The value of this property is initially set by the
name attribute of the <a>
tag.

text [Netscape 4]

This property specifies the plain text,
if any, between the <a> and
</a> tags of an anchor. Note that this
property works correctly only if there are no intervening HTML tags
between the <a> and
</a> tags. If there are other HTML tags, the
text property may contain only a portion of the
anchor text.

HTMLElement.innerText provides the IE 4 equivalent
of this Netscape-specific property.

HTML Syntax

An Anchor object
is created by any standard HTML <a> tag that
contains a name attribute:

<a
name="name" // Links may refer to this anchor by this name
>
text
</a>

Description

An anchor is a named location within an
HTML document. Anchors are created with an
<a> tag that has a name
attribute specified. The Document object has an
anchors[] array property that contains Anchor
objects that represent each of the anchors in the document. This
anchors[] array has existed since JavaScript 1.0,
but the Anchor object was not implemented until JavaScript 1.2.
Therefore, the elements of anchors[] were
null until JavaScript 1.2.

Note that the <a> tag used to create anchors
is also used to create hypertext links. Although hypertext links are
often called anchors in HTML parlance, they are represented in
JavaScript with the Link object, not with the Anchor object. In the
DOM reference section of this book, however, both anchors and links
are documented under HTMLAnchorElement.
