HTML-DOM nodeType- Eigenschaft

Element-Objekt

Beispiel

Rufen Sie den Knotentyp des Body-Elements ab:

var x = document.getElementById("myP").nodeType;

Weitere „Probieren Sie es selbst“-Beispiele weiter unten.


Definition und Verwendung

Die Eigenschaft nodeType gibt den Knotentyp des angegebenen Knotens als Zahl zurück.

Wenn der Knoten ein Elementknoten ist, gibt die nodeType-Eigenschaft 1 zurück.

Wenn der Knoten ein Attributknoten ist, gibt die nodeType-Eigenschaft 2 zurück.

Wenn der Knoten ein Textknoten ist, gibt die nodeType-Eigenschaft 3 zurück.

Wenn der Knoten ein Kommentarknoten ist, gibt die nodeType-Eigenschaft 8 zurück.

Diese Eigenschaft ist schreibgeschützt.


Browser-Unterstützung

Property
nodeType Yes Yes Yes Yes Yes

Syntax

node.nodeType


Technische Details

Rückgabewert: Eine Zahl, die den Knotentyp des Knotens darstellt
DOM-Version Knotenobjekt der Kernebene 1

Knotentypen

Dokumente, Elemente, Attribute und andere Aspekte eines HTML- oder XML-Dokuments haben unterschiedliche Knotentypen.

Es gibt 12 verschiedene Knotentypen, die Kinder verschiedener Knotentypen haben können:

Node type Description Children
1 Element Represents an element Element, Text, Comment, ProcessingInstruction, CDATASection, EntityReference
2 Attr Represents an attribute Text, EntityReference
3 Text Represents textual content in an element or attribute None
4 CDATASection Represents a CDATA section in a document (text that will NOT be parsed by a parser) None
5 EntityReference Represents an entity reference Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
6 Entity Represents an entity Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
7 ProcessingInstruction Represents a processing instruction None
8 Comment Represents a comment None
9 Document Represents the entire document (the root-node of the DOM tree) Element, ProcessingInstruction, Comment, DocumentType
10 DocumentType Provides an interface to the entities defined for the document None
11 DocumentFragment Represents a "lightweight" Document object, which can hold a portion of a document Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
12 Notation Represents a notation declared in the DTD None

Knotentypen - Rückgabewerte

Der Rückgabewert der Eigenschaften nodeName und nodeValue für jeden Knotentyp:

Node type nodeName returns nodeValue returns
1 Element element name null
2 Attr attribute name attribute value
3 Text #text content of node
4 CDATASection #cdata-section content of node
5 EntityReference entity reference name null
6 Entity entity name null
7 ProcessingInstruction target content of node
8 Comment #comment comment text
9 Document #document null
10 DocumentType doctype name null
11  DocumentFragment #document fragment null
12 Notation notation name null

NodeTypes - Benannte Konstanten

NodeType Named Constant
1 ELEMENT_NODE
2 ATTRIBUTE_NODE
3 TEXT_NODE
4 CDATA_SECTION_NODE
5 ENTITY_REFERENCE_NODE
6 ENTITY_NODE
7 PROCESSING_INSTRUCTION_NODE
8 COMMENT_NODE
9 DOCUMENT_NODE
10 DOCUMENT_TYPE_NODE
11 DOCUMENT_FRAGMENT_NODE
12 NOTATION_NODE

Mehr Beispiele

Beispiel

Rufen Sie den Knotentyp des <body>-Elements ab:

var x = document.body.nodeType;

Beispiel

Rufen Sie die Knotentypen der untergeordneten Knoten des <body>-Elements ab:

var c = document.body.childNodes;
var txt = "";
var i;
for (i = 0; i < c.length; i++) {
  txt = txt + c[i].nodeType + "<br>";
}

document.getElementById("demo").innerHTML = txt;

Beispiel

Rufen Sie den Knotennamen, den Knotenwert und den Knotentyp des ersten untergeordneten Knotens des <div>-Elements ab:

<div id="myDIV">This is a div element.</div>

<script>
var x = document.getElementById("myDIV").firstChild;
var txt = "";
txt += "The node name: " + x.nodeName + "<br>";
txt += "The node value: " + x.nodeValue + "<br>";
txt += "The node type: " + x.nodeType;
</script>
