Element Class

The

Element
interface represents an element in an HTML or XML document. Elements may have attributes associated with them; since the
Element
interface inherits from
Node
, the generic
Node
interface attribute
attributes
may be used to retrieve the set of all attributes for an element. There are methods on the
Element
interface to retrieve either an
Attr
object by name or an attribute value by name. In XML, where an attribute value may contain entity references, an
Attr
object should be retrieved to examine the possibly fairly complex sub-tree representing the attribute value. On the other hand, in HTML, where all attributes have simple string values, methods to directly access an attribute value can safely be used as a convenience.In DOM Level 2, the method
normalize
is inherited from the
Node
interface where it was moved.

Methods

Name Description
addEventListener(string, EventListener, bool)
dispatchEvent(DOMEvent)
getAttribute(string) Retrieves an attribute value by name.
getAttributeNode(string) Retrieves an attribute node by name.
To retrieve an attribute node by qualified name and namespace URI, use the
getAttributeNodeNS
method.
getAttributeNodeNS(string, string) Retrieves an
Attr
node by local name and namespace URI. HTML-only DOM implementations do not need to implement this method.
getAttributeNS(string, string) Retrieves an attribute value by local name and namespace URI. HTML-only DOM implementations do not need to implement this method.
getElementsByTagName(string) Returns a
NodeList
of all descendant
Elements
with a given tag name, in the order in which they are encountered in a preorder traversal of this
Element
tree.
getElementsByTagNameNS(string, string) Returns a
NodeList
of all the descendant
Elements
with a given local name and namespace URI in the order in which they are encountered in a preorder traversal of this
Element
tree.
HTML-only DOM implementations do not need to implement this method.
hasAttribute(string) Returns
true
when an attribute with a given name is specified on this element or has a default value,
false
otherwise.
hasAttributeNS(string, string) Returns
true
when an attribute with a given local name and namespace URI is specified on this element or has a default value,
false
otherwise. HTML-only DOM implementations do not need to implement this method.
querySelector(string)
querySelectorAll(string)
removeAttribute(string) Removes an attribute by name. If the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
To remove an attribute by local name and namespace URI, use the
removeAttributeNS
method.
removeAttributeNode(Attr) Removes the specified attribute node. If the removed
Attr
has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.
removeAttributeNS(string, string) Removes an attribute by local name and namespace URI. If the removed attribute has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix.
HTML-only DOM implementations do not need to implement this method.
removeEventListener(string, EventListener, bool)
setAttribute(string, string) Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an
Attr
node plus any
Text
and
EntityReference
nodes, build the appropriate subtree, and use
setAttributeNode
to assign it as the value of an attribute.
To set an attribute with a qualified name and namespace URI, use the
setAttributeNS
method.
setAttributeNode(Attr) Adds a new attribute node. If an attribute with that name (
nodeName
) is already present in the element, it is replaced by the new one.
To add a new attribute node with a qualified name and namespace URI, use the
setAttributeNodeNS
method.
setAttributeNodeNS(Attr) Adds a new attribute. If an attribute with that local name and that namespace URI is already present in the element, it is replaced by the new one.
HTML-only DOM implementations do not need to implement this method.
setAttributeNS(string, string, string) Adds a new attribute. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the
qualifiedName
, and its value is changed to be the
value
parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an
Attr
node plus any
Text
and
EntityReference
nodes, build the appropriate subtree, and use
setAttributeNodeNS
or
setAttributeNode
to assign it as the value of an attribute.
HTML-only DOM implementations do not need to implement this method.

tagName The name of the element. For example, in:

tagName
has the value
"elementExample"
. Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the
tagName
of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document.
