{{domref}}

A Node is an interface from which a number of DOM types inherit, and allows these various types to be treated (or tested) similarly.
The following all inherit this interface and its methods and properties (though they may return null in particular cases where not relevant; or throw an exception when adding children to a node type for which no children can exist): {{domxref("Document")}}, {{domxref("Element")}}, {{domxref("Attr")}}, {{domxref("CharacterData")}} (which {{domxref("Text")}}, {{domxref("Comment")}}, and {{domxref("CDATASection")}} inherit), {{domxref("ProcessingInstruction")}}, {{domxref("DocumentFragment")}}, {{domxref("DocumentType")}}, {{domxref("Notation")}}, {{domxref("Entity")}}, {{domxref("EntityReference")}}

Properties

Inherits properties from its parents {{domxref("EventTarget")}}.[1]

{{domxref("Node.attributes")}} {{deprecated_inline}}
...
{{domxref("Node.baseURI")}} {{readonlyInline}}
Returns a {{domxref("DOMString")}} representing the base URL. The concept of base URL changes from one language to another; in HTML, it corresponds to the protocol, the domain name and the directory structure, that is all until the last '/'.
{{domxref("Node.baseURIObject")}} {{Non-standard_inline()}} {{ Fx_minversion_inline("3") }}
(Not available to web content.) The read-only {{ Interface("nsIURI") }} object representing the base URI for the element.
{{domxref("Node.childNodes")}} {{readonlyInline}}
Returns a live {{domxref("NodeList")}} containing all the children of this node. {{domxref("NodeList")}} being live means that if the children of the Node change, the {{domxref("NodeList")}} object is automatically updated.
{{domxref("Node.firstChild")}} {{readonlyInline}}
Returns a {{domxref("Node")}} representing the first direct child node of the node, or null if the node has no child.
{{domxref("Node.lastChild")}} {{readonlyInline}}
Returns a {{domxref("Node")}} representing the last direct child node of the node, or null if the node has no child.
{{domxref("Node.localName")}} {{readonlyInline}}{{obsolete_inline}}
Returns a {{domxref("DOMString")}} representing the local part of the qualified name of an element. In Firefox 3.5 and earlier, the property upper-cases the local name for HTML elements (but not XHTML elements). In later versions, this does not happen, so the property is in lower case for both HTML and XHTML. {{ gecko_minversion_inline("1.9.2") }}
Though the specification requires localName to be defined on the {{domxref("Node")}} interface, Gecko-based browsers implement it on the {{domxref("Element")}} interface.
{{domxref("Node.namespaceURI")}} {{readonlyInline}}{{obsolete_inline}}
The namespace URI of this node, or null if it is no namespace. In Firefox 3.5 and earlier, HTML elements are in no namespace. In later versions, HTML elements are in the http://www.w3.org/1999/xhtml namespace in both HTML and XML trees. {{ gecko_minversion_inline("1.9.2") }}
Though the specification requires namespaceURI to be defined on the {{domxref("Node")}} interface, Gecko-based browsers implement it on the {{domxref("Element")}} interface.
{{domxref("Node.nextSibling")}} {{readonlyInline}}
Returns a {{domxref("Node")}} representing the next node in the tree, or null if there isn't such node.
{{domxref("Node.nodeName")}} {{readonlyInline}}
Returns a {{domxref("DOMString")}} containing the name of the Node. The structure of the name will differ with the name type. E.g. An {{domxref("HTMLElement")}} will contain the name of the corresponding tag, like 'audio' for an {{domxref("HTMLAudioElement")}}, a {{domxref("Text")}} node will have the '#text' string, or a {{domxref("Document")}} node will have the '#document' string.
{{domxref("Node.nodePrincipal")}} {{Non-standard_inline()}}{{ Fx_minversion_inline("3") }}
A {{ Interface("nsIPrincipal") }} representing the node principal.
{{domxref("Node.nodeType")}}{{readonlyInline}}
Returns an unsigned short representing the type of the node. Possible values are:
Name Value
ELEMENT_NODE 1
ATTRIBUTE_NODE {{deprecated_inline()}} 2
TEXT_NODE 3
CDATA_SECTION_NODE {{deprecated_inline()}} 4
ENTITY_REFERENCE_NODE {{deprecated_inline()}} 5
ENTITY_NODE {{deprecated_inline()}} 6
PROCESSING_INSTRUCTION_NODE 7
COMMENT_NODE 8
DOCUMENT_NODE 9
DOCUMENT_TYPE_NODE 10
DOCUMENT_FRAGMENT_NODE 11
NOTATION_NODE {{deprecated_inline()}} 12
{{domxref("Node.nodeValue")}}
Is a {{domxref("DOMString")}} representing the value of an object. For most Node type, this returns null and any set operation is ignored. For nodes of type TEXT_NODE ({{domxref("Text")}} objects), COMMENT_NODE ({{domxref("Comment")}} objects), and PROCESSING_INSTRUCTION_NODE ({{domxref("ProcessingInstruction")}} objects), the value corresponds to the text data contained in the object.
{{domxref("Node.ownerDocument")}} {{readonlyInline}}
Returns the {{domxref("Document")}} that this node belongs to. If no document is associated with it, returns null.
{{domxref("Node.parentNode")}} {{readonlyInline}}
Returns a {{domxref("Node")}} that is the parent of this node. If there is no such node, like if this node is the top of the tree or if doesn't participate in a tree, this property returns null.
{{domxref("Node.parentElement")}} {{readonlyInline}}
Returns an {{domxref("Element")}} that is the parent of this node. If the node has no parent, or if that parent is not an {{domxref("Element")}}, this property returns null.
{{domxref("Node.prefix")}} {{obsolete_inline}}
Is a {{domxref("DOMString")}} representing the namespace prefix of the node, or null if no prefix is specified.
Though the specification requires localName to be defined on the {{domxref("Node")}} interface, Gecko-based browsers implement it on the {{domxref("Element")}} interface.
{{domxref("Node.previousSibling")}} {{readonlyInline}}
Returns a {{domxref("Node")}} representing the previous node in the tree, or null if there isn't such node.
{{domxref("Node.textContent")}}
Is a {{domxref("DOMString")}} representing the textual content of an element and all its descendants.

Methods

Inherits methods from its parents {{domxref("EventTarget")}}.[1]

{{domxref("Node.appendChild()")}}
Insert a {{domxref("Node")}} as the last child node of this element.
{{domxref("Node.cloneNode()")}}
Clone a {{domxref("Node")}}, and optionally, all of its contents. By default, it clones the content of the node.
{{domxref("Node.compareDocumentPosition()")}}
 
{{domxref("Node.contains()")}}
 
{{domxref("Node.getFeature()")}} {{obsolete_inline("7.0")}}
...
{{domxref("Node.getUserData()")}} {{obsolete_inline("22.0")}}
...
{{domxref("Node.hasAttributes()")}} {{obsolete_inline("22.0")}}
Returns a {{domxref("Boolean")}} indicating if the element has any attributes, or not.
{{domxref("Node.hasChildNodes()")}}
Returns a {{domxref("Boolean")}} indicating if the element has any child nodes, or not.
{{domxref("Node.insertBefore")}}
Inserts the first {{domxref("Node")}} given in a parameter immediately before the second, child of this element, {{domxref("Node")}}.
{{domxref("Node.isDefaultNamespace")}}
 
{{domxref("Node.isEqualNode")}}
 
{{domxref("Node.isSameNode")}} {{deprecated_inline("9.0")}} {{obsolete_inline("10.0")}}
 
{{domxref("Node.isSupported")}} {{obsolete_inline("22.0")}}
 
{{domxref("Node.lookupPrefix")}}
 
{{domxref("Node.lookupNamespaceURI")}}
 
{{domxref("Node.normalize")}}
Clean up all the text nodes under this element (merge adjacent, remove empty).
{{domxref("Node.removeChild")}}
Removes the {{domxref("Node")}} Removes a child node from the current element, which must be a child of the current node.
{{domxref("Node.replaceChild")}}
Replaces one child {{domxref("Node")}} of the current one with the second one given in parameter.
{{domxref("Node.setUserData")}} {{obsolete_inline("22.0")}}
 

Examples

Browse all child nodes

The following function recursively cycle all child nodes of a node and execute a callback function upon them (and upon the parent node itself).

function DOMComb (oParent, oCallback) {
  if (oParent.hasChildNodes()) {
    for (var oNode = oParent.firstChild; oNode; oNode = oNode.nextSibling) {
      DOMComb(oNode, oCallback);
    }
  }
  oCallback.call(oParent);
}

Syntax

DOMComb(parentNode, callbackFunction);

Description

Recursively cycle all child nodes of parentNode and parentNode itself and execute the callbackFunction upon them as this objects.

Parameters

parentNode
The parent node (Node Object).
callbackFunction
The callback function (Function).

Sample usage

The following example send to the console.log the text content of the body:

function printContent () {
  if (this.nodeValue) { console.log(this.nodeValue); }
}

onload = function () {
  DOMComb(document.body, printContent);
};

Specifications

Specification Status Comment
{{SpecName('DOM WHATWG', '#interface-node', 'Node')}} {{Spec2('DOM WHATWG')}} Removed the following properties: attributes, namespaceURI, prefix, and localName.
Removed the following methods: isSupported(), hasAttributes(), isSameNode(), getFeature(), setUserData(), and getUserData().
{{SpecName('DOM3 Core', 'core.html#ID-1950641247', 'Node')}} {{Spec2('DOM3 Core')}} The methods insertBefore(), replaceChild(), removeChild(), and appendChild() returns one more kind of error (NOT_SUPPORTED_ERR) if called on a {{domxref("Document")}}.
The normalize() method has been modified so that {{domxref("Text")}} node can also be normalized if the proper {{domxref("DOMConfiguration")}} flag is set.
Added the following methods: compareDocumentPosition(), isSameNode(), lookupPrefix(), isDefaultNamespace(), lookupNamespaceURI(), isEqualNode(), getFeature(), setUserData(), and getUserData().
Added the following properties: baseURI and textContent.
{{SpecName('DOM2 Core', 'core.html#ID-1950641247', 'Node')}} {{Spec2('DOM2 Core')}} The ownerDocument property was slightly modified so that {{domxref("DocumentFragment")}} also returns null.
Added the following properties: namespaceURI, prefix, and localName.
Added the following methods: normalize(), isSupported() and hasAttributes().
{{SpecName('DOM1', 'level-one-core.html#ID-1950641247', 'Node')}} {{Spec2('DOM1')}} Initial definition.
