In-Depth Information
There are other types not covered in the table, but these aren't used in HTML documents.
As we can see from the table, a code of
1
confirms that
body
is an element node.
We can also use the
nodeName
property to find the name of the element:
body.nodeName;
<< "BODY"
Note that the element name is returned in upper-case letters.
Legacy DOM Shortcut Methods
There are some methods from DOM Level 0 that can still be employed to access commonly

•
document.body
returns the body element of a web page, as we saw in the pre-
vious example.
•
document.images
returns a node list of all the images contained in the docu-
ment.
•
document.links
returns a node list of all the
<a>
elements and
<area>
ele-
ments that have an
href
attribute.
•
document.anchors
returns a node list of all the
<a>
elements that have a
name
attribute.
•
document.forms
returns a node list of all the forms in the document. This will
Warning: Array-

each item using index notation. For example,
document.images[0]
will return the first image in the node list of all the images in the document.
They also have a
length
property, which can be used to iterate through
every element using a
for
loop, like so:
