Метод Node.contains() повертає значення {{jsxref("Boolean")}}, яке вказує, чи переданий вузол є нащадком заданого вузла чи ні.

+ +

Синтаксис

+ +
node.contains( otherNode )
+
+ +

Приклад

+ +

Ця функція перевіряє, чи елемент знаходиться в тілі сторінки. А також визначає чи тіло сторінки включає само себе. Якщо включає само себе, то відповідно метод isInPage буде повертати false. В іншому випадку буде повертатися true або false в залежності від того, чи елемент існує всередині тіла сторінки.

+ +
function isInPage(node) {
+  return (node === document.body) ? false : document.body.contains(node);
+}

{{APIRef("DOM")}}
+ +

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 interfaces all inherit from Node its methods and properties: {{domxref("Document")}}, {{domxref("Element")}}, {{domxref("CharacterData")}} (which {{domxref("Text")}}, {{domxref("Comment")}}, and {{domxref("CDATASection")}} inherit), {{domxref("ProcessingInstruction")}}, {{domxref("DocumentFragment")}}, {{domxref("DocumentType")}}, {{domxref("Notation")}}, {{domxref("Entity")}}, {{domxref("EntityReference")}}

+ +

These interfaces may return null in particular cases where the methods and properties are not relevant. They may throw an exception - for example when adding children to a node type for which no children can exist.

+ +

Properties

+ +

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

+ +
+
{{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")}} {{obsolete_inline}}{{readonlyInline}}
+
Returns a {{domxref("DOMString")}} representing the local part of the qualified name of an element. +
+

Note: 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")}}

+
+
+
{{domxref("Node.namespaceURI")}} {{obsolete_inline}}{{readonlyInline}}
+
The namespace URI of this node, or null if it is no namespace. +
+

Note: In Firefox 3.5 and earlier, HTML elements are in no namespace. In later versions, HTML elements are in the https://www.w3.org/1999/xhtml/ namespace in both HTML and XML trees. {{gecko_minversion_inline("1.9.2")}}

+
+
+
{{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: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+
{{domxref("Node.nodeValue")}}
+
Returns / Sets the value of the current node
+
{{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}}{{readonlyInline}}
+
Is a {{domxref("DOMString")}} representing the namespace prefix of the node, or null if no prefix is specified.
+
{{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.rootNode")}} {{readOnlyInline}}
+
Returns a {{domxref("Node")}} object representing the topmost node in the tree, or the current node if it's the topmost node in the tree. This is found by walking backward along {{domxref("Node.parentNode")}} until the top is reached.
+
{{domxref("Node.textContent")}}
+
Returns / Sets the textual content of an element and all its descendants.
+
+ +

Methods

+ +

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

+ +
+
{{domxref("Node.appendChild()")}}
+

+ 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.
+
{{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}}

+
{{domxref("Node.lookupPrefix()")}}
+
{{domxref("Node.lookupNamespaceURI()")}}

Examples

+ +

Browse all child nodes

+ +

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);
+};
+ +

Remove all children nested within a node

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

Sample usage

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

[1] WebKit and old versions of Blink incorrectly do not make Node inherit from {{domxref("EventTarget")}}.

[2] In Gecko 22.0 {{geckoRelease("22.0")}} the attributes property was moved to {{domxref("Element")}}.

+ +

[3] The properties were moved to the {{domxref("Element")}} and {{domxref("Attr")}} APIs according to the DOM4 standard.
