DOM 节点 接口是许多其它 DOM API 对象所基于的抽象基类，因此能使这些对象类型使用类似且可经常互换。 作为抽象类，没有这种事情作为纯 节点 对象。所有对象实现的 节点 功能均基于其某一子类。最值得注意的是 Document , 元素 ，和 DocumentFragment .

此外，每种 DOM 节点都通过接口表示基于 节点 。这些包括 Attr , CharacterData (which 文本 , 注释 ，和 CDATASection 全都基于)， ProcessingInstruction , DocumentType , Notation , Entity ，和 EntityReference .

在某些情况下，特定特征在基 节点 interface may not apply to one of its child interfaces; in that case, the inheriting node may return null 或根据情况抛出异常。例如：尝试把子级添加到不可以有子级的节点类型会抛出异常。 

  <div id="interfaceDiagram" style="display: inline-block; position: relative; width: 100%; padding-bottom: 11.666666666666666%; vertical-align: middle; overflow: hidden;"><svg style="display: inline-block; position: absolute; top: 0; left: 0;" viewbox="-50 0 600 70" preserveAspectRatio="xMinYMin meet"><a xlink:href="../API/EventTarget.html" target="_top"><rect x="1" y="1" width="110" height="50" fill="#fff" stroke="#D4DDE4" stroke-width="2px" /><text  x="56" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">EventTarget</text></a><polyline points="111,25  121,20  121,30  111,25" stroke="#D4DDE4" fill="none"/><line x1="121" y1="25" x2="151" y2="25" stroke="#D4DDE4"/><a xlink:href="../API/Node" target="_top"><rect x="151" y="1" width="75" height="50" fill="#F4F7F8" stroke="#D4DDE4" stroke-width="2px" /><text  x="188.5" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">Node</text></a></svg></div>

特性

除以下特性外， 节点 继承的特性来自其父级， EventTarget .

Node.baseURI 只读
返回 DOMString representing the base URL of the document containing the 节点 .
Node.baseURIObject 只读
(Not available to web content.) The nsIURI object representing the base URI for the element.
Node.childNodes 只读
返回实时 NodeList containing all the children of this node. NodeList being live means that if the children of the 节点 change, the NodeList object is automatically updated.
Node.firstChild 只读
返回 节点 representing the first direct child node of the node, or null if the node has no child.
Node.isConnected 只读
A boolean indicating whether or not the Node is connected (directly or indirectly) to the context object, e.g. the Document object in the case of the normal DOM, or the ShadowRoot in the case of a shadow DOM.
Node.lastChild 只读
返回 节点 representing the last direct child node of the node, or null if the node has no child.
Node.nextSibling 只读
返回 节点 representing the next node in the tree, or null if there isn't such node.
Node.nodeName 只读
返回 DOMString containing the name of the 节点 . The structure of the name will differ with the node type. E.g. An HTMLElement will contain the name of the corresponding tag, like 'audio' 对于 HTMLAudioElement ， 文本 node will have the '#text' string, or a Document node will have the '#document' 字符串。
Node.nodeType 只读
返回 unsigned short representing the type of the node. Possible values are:
名称 值
ELEMENT_NODE 1
ATTRIBUTE_NODE 2
TEXT_NODE 3
CDATA_SECTION_NODE 4
ENTITY_REFERENCE_NODE 5
ENTITY_NODE 6
PROCESSING_INSTRUCTION_NODE 7
COMMENT_NODE 8
DOCUMENT_NODE 9
DOCUMENT_TYPE_NODE 10
DOCUMENT_FRAGMENT_NODE 11
NOTATION_NODE 12
Node.nodeValue

Returns / Sets the value of the current node.

Node.ownerDocument 只读
返回 Document that this node belongs to. If the node is itself a document, returns null .
Node.parentNode 只读
返回 节点 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 只读
返回 元素 that is the parent of this node. If the node has no parent, or if that parent is not an 元素 , this property returns null .
Node.previousSibling 只读
返回 节点 representing the previous node in the tree, or null if there isn't such node.
Node.textContent

Returns / Sets the textual content of an element and all its descendants.

过时特性

Node.localName 只读
返回 DOMString representing the local part of the qualified name of an element.

注意： 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.

Node.namespaceURI 只读
The namespace URI of this node, or null if it is no namespace.

注意： 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.

Node.nodePrincipal 从 Gecko 46 起已过时
A nsIPrincipal representing the node principal.
Node.prefix 只读
是 DOMString representing the namespace prefix of the node, or null if no prefix is specified.
Node.rootNode 只读
返回 节点 object representing the topmost node in the tree, or the current node if it's the topmost node in the tree. This has been replaced by Node.getRootNode() .

方法

除以下特性外， 节点 继承来自其父级的方法， EventTarget .

Node.appendChild( childNode )
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()
克隆 节点 , and optionally, all of its contents. By default, it clones the content of the node.
Node.compareDocumentPosition()

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

Node.contains()
返回 布尔 value indicating whether or not a node is a descendant of the calling node.
Node.getBoxQuads()

Returns a list of the node's CSS boxes relative to another node.

Node.getRootNode()

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

Node.hasChildNodes()
返回 布尔 indicating whether or not the element has any child nodes.
Node.insertBefore()
插入 节点 before the reference node as a child of a specified parent node.
Node.isDefaultNamespace()
Accepts a namespace URI as an argument and returns a 布尔 采用值 true if the namespace is the default namespace on the given node or false 若不。
Node.isEqualNode()
返回 布尔 which indicates whether or not two nodes are of the same type and all their defining data points match.
Node.isSameNode()
返回 布尔 value indicating whether or not the two nodes are the same (that is, they reference the same object).
Node.lookupPrefix()
返回 DOMString 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()
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()

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

Node.replaceChild()
Replaces one child 节点 of the current one with the second one given in parameter.

过时方法

Node.getUserData()
Allows a user to get some DOMUserData from the node.
Node.hasAttributes()
返回 布尔 indicating if the element has any attributes, or not.
Node.isSupported()
返回 布尔 flag containing the result of a test whether the DOM implementation implements a specific feature and this feature is supported by the specific node.
Node.setUserData()
Allows a user to attach, or remove, DOMUserData to the node.

范例

移除嵌套在节点中的所有子级 

function removeAllChildren(element) {
  while (element.firstChild) {
    element.removeChild(element.firstChild)
  }
}

样本用法 

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

递归遍历子级节点

The following function recursively calls a callback function for each node contained by a root node (including the root itself): 

function eachNode(rootNode, callback) {
	if (!callback) {
		const nodes = []
		eachNode(rootNode, function(node) {
			nodes.push(node)
		})
		return nodes
	}
	if (false === callback(rootNode)) {
		return false
    }
	if (rootNode.hasChildNodes()) {
		const nodes = rootNode.childNodes
		for (let i = 0, l = nodes.length; i < l; ++i) {
			if (false === eachNode(nodes[i], callback)) {
				return
            }
        }
	}
}

句法 

eachNode(rootNode, callback)

描述

Recursively calls a function for each descendant node of rootNode (including the root itself).

若 callback is omitted, the function returns an 数组 instead, which contains rootNode and all nodes contained within.

若 callback is provided, and it returns 布尔 false when called, the current recursion level is aborted, and the function resumes execution at the last parent's level. This can be used to abort loops once a node has been found (such as searching for a text node which contains a certain string).

参数

rootNode
节点 object whose descendants will be recursed through.
callback 可选
An optional callback function that receives a 节点 as its only argument. If omitted, eachNode 返回 数组 of every node contained within rootNode (including the root itself).

样本用法

The following example prints the textContent properties of each <span> tag in a <div> element named "box" : 

<div id="box">
  <span>Foo</span>
  <span>Bar</span>
  <span>Baz</span>
</div>
								
const box = document.getElementById("box")
eachNode(box, function(node) {
  if (null != node.textContent) {
    console.log(node.textContent)
  }
})

The above will result in the following strings printing to the user's console: 

"\n\t", "Foo", "\n\t", "Bar", "\n\t", "Baz"

注意： Whitespace forms part of a 文本 node, meaning indentation and newlines form separate 文本 between the 元素 节点。

现实用法

The following demonstrates a real-world use of the eachNode() function: searching for text on a web-page.

We use a wrapper function named grep to do the searching: 

function grep(parentNode, pattern) {
	const matches = []
	let endScan = false
	eachNode(parentNode, function(node){
		if (endScan) {
			return false
        }
		// Ignore anything which isn't a text node
		if (node.nodeType !== Node.TEXT_NODE) {
			return
        }
		if (typeof pattern === "string") {
			if (-1 !== node.textContent.indexOf(pattern)) {
				matches.push(node)
            }
		}
		else if (pattern.test(node.textContent)) {
			if (!pattern.global) {
				endScan = true
				matches = node
			}
			else {
                matches.push(node)
            }
		}
	})
	return matches
}

For example, to find 文本 nodes that contain typos: 

const typos = ["teh", "adn", "btu", "adress", "youre", "msitakes"]
const pattern = new RegExp("\\b(" + typos.join("|") + ")\\b", "gi")
const mistakes = grep(document.body, pattern)
console.log(mistakes)
