nodeName and nodeValue Properties

nodeName and nodeValue give specific information about the node. The values of nodeName and nodeValue are dependent on the node type.

 
<!DOCTYPE HTML> 
<html> 
    <head>

    </head> 
    <body> 
        <pre id="results"></pre> 
        <script> 
            var resultsElement = document.getElementById("results"); 
            document.writeln(resultsElement.nodeType); 
            document.writeln(resultsElement.nodeName); 
        </script> 
    </body> 
</html>
