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.
