Node.nodeName
The Node.nodeName
read-only property returns the name of the current node as a string.
The returned values for different types of nodes are:
Interface | nodeName value |
---|---|
Attr |
The value of Attr.name |
CDATASection |
"#cdata-section" |
Comment |
"#comment" |
Document |
"#document" |
DocumentFragment |
"#document-fragment" |
DocumentType |
The value of DocumentType.name |
Element |
The value of Element.tagName |
Entity |
The entity name |
EntityReference |
The name of entity reference |
Notation |
The notation name |
ProcessingInstruction |
The value of ProcessingInstruction.target |
Text |
"#text" |
Syntax
var str = node.nodeName;
Example
Given the following markup:
<div id="d1">hello world</div> <input type="text" id="t"/>
and the following script:
var div1 = document.getElementById("d1"); var text_field = document.getElementById("t"); text_field.value = div1.nodeName;
In XHTML (or any other XML format), text_field
's value would read "div". However, in HTML, text_field
's value would read "DIV", because nodeName
and tagName
return in upper case on HTML elements in DOMs flagged as HTML documents. Read more details on nodeName case sensitivity in different browsers.
Note that tagName
property could have been used instead, since nodeName
has the same value as tagName
for an element. Bear in mind, however, that nodeName
will return #text
for text nodes while tagName
will return undefined
.
