• Node.baseURI (en-US) 읽기 전용
  • : Returns a 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 '/'.
• Node.baseURIObject (en-US) 비표준
  • : (Not available to web content.) The read-only nsIURI object representing the base URI for the element.
• Node.childNodes 읽기 전용
  • : Returns a live NodeList containing all the children of this node. NodeList being live means that if the children of the Node change, the NodeList object is automatically updated.
• Node.firstChild 읽기 전용
  • : Returns a Node representing the first direct child node of the node, or null if the node has no child.
• Node.lastChild 읽기 전용
  • : Returns a Node representing the last direct child node of the node, or null if the node has no child.
• Node.localName (en-US) 지원이 중단되었습니다 읽기 전용
  • : Returns a 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. Though recent specifications require localName to be defined on the Element interface, Gecko-based browsers still implement it on the Node interface.
• Node.namespaceURI (en-US) 지원이 중단되었습니다 읽기 전용
  • : 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. Though recent specifications require namespaceURI to be defined on the Element interface, Gecko-based browsers still implement it on the Node interface.
• Node.nextSibling 읽기 전용
  • : Returns a Node representing the next node in the tree, or null if there isn't such node.
• Node.nodeName (en-US) 읽기 전용
  • : Returns a DOMString containing the name of the Node. The structure of the name will differ with the name type. E.g. An HTMLElement will contain the name of the corresponding tag, like 'audio' for an HTMLAudioElement (en-US), a Text node will have the '#text' string, or a Document node will have the '#document' string.
• Node.nodePrincipal (en-US) 비표준
  • : A nsIPrincipal representing the node principal.
• Node.nodeType (en-US)읽기 전용

  • : Returns an unsigned short representing the type of the node. Possible values are:	Name	Value
    ELEMENT_NODE	1
    ATTRIBUTE_NODE 지원이 중단되었습니다	2
    TEXT_NODE	3
    CDATA_SECTION_NODE 지원이 중단되었습니다	4
    ENTITY_REFERENCE_NODE 지원이 중단되었습니다	5
    ENTITY_NODE 지원이 중단되었습니다	6
    PROCESSING_INSTRUCTION_NODE	7
    COMMENT_NODE	8
    DOCUMENT_NODE	9
    DOCUMENT_TYPE_NODE	10
    DOCUMENT_FRAGMENT_NODE	11
    NOTATION_NODE 지원이 중단되었습니다	12

• Node.nodeValue (en-US)
  • : Is a 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 (Text objects), COMMENT_NODE (Comment objects), and PROCESSING_INSTRUCTION_NODE (ProcessingInstruction (en-US) objects), the value corresponds to the text data contained in the object.
• Node.ownerDocument 읽기 전용
  • : Returns the Document that this node belongs to. If no document is associated with it, returns null.
• Node.parentNode (en-US) 읽기 전용
  • : Returns a 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.
• Node.parentElement (en-US) 읽기 전용
  • : Returns an Element that is the parent of this node. If the node has no parent, or if that parent is not an Element, this property returns null.
• Node.prefix (en-US) 지원이 중단되었습니다 읽기 전용
  • : Is a DOMString representing the namespace prefix of the node, or null if no prefix is specified. Though recent specifications require prefix to be defined on the Element interface, Gecko-based browsers still implement it on the Node interface.
• Node.previousSibling 읽기 전용
  • : Returns a Node representing the previous node in the tree, or null if there isn't such node.
• Node.textContent
  • : Is a DOMString representing the textual content of an element and all its descendants.

Node.appendChild()

Adds the specified childNode argument as the last child to the current node. If the argument referenced an existing node on the DOM tree, the node will be detached from its current position and attached at the new position.

Node.cloneNode()

Clone a Node, and optionally, all of its contents. By default, it clones the content of the node.

Node.compareDocumentPosition() (en-US)

Compares the position of the current node against another node in any other document.

Node.contains()

Returns true or false value indicating whether or not a node is a descendant of the calling node.

Node.getRootNode() (en-US)

Returns the context object's root which optionally includes the shadow root if it is available.

Node.hasChildNodes()

Returns a boolean value indicating whether or not the element has any child nodes.

Node.insertBefore()

Inserts a Node before the reference node as a child of a specified parent node.

Node.isDefaultNamespace() (en-US)

Accepts a namespace URI as an argument and returns a boolean value with a value of true if the namespace is the default namespace on the given node or false if not.

Node.isEqualNode() (en-US)

Returns a boolean value which indicates whether or not two nodes are of the same type and all their defining data points match.

Node.isSameNode() (en-US)

Returns a boolean value indicating whether or not the two nodes are the same (that is, they reference the same object).

Node.lookupPrefix() (en-US)

Returns a string containing the prefix for a given namespace URI, if present, and null if not. When multiple prefixes are possible, the result is implementation-dependent.

Node.lookupNamespaceURI() (en-US)

Accepts a prefix and returns the namespace URI associated with it on the given node if found (and null if not). Supplying null for the prefix will return the default namespace.

Node.normalize()

Clean up all the text nodes under this element (merge adjacent, remove empty).

Node.removeChild() (en-US)

Removes a child node from the current element, which must be a child of the current node.

Node.replaceChild()

Replaces one child Node of the current one with the second one given in parameter.

The following function recursively cycles all child nodes of a node and executes 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);
};

Element.prototype.removeAll = function () {
  while (this.firstChild) { this.removeChild(this.firstChild); }
  return this;
};

Sample usage

/* ... an alternative to document.body.innerHTML = "" ... */
document.body.removeAll();
