    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.
