Returns the name of the element.
Syntax
elementName = element.tagName;
elementNameis a string containing the name of the current element.
Notes
In XML (and XML-based languages such as XHTML), tagName preserves case. On HTML elements in DOM trees flagged as HTML documents, tagName returns the element name in the uppercase form. The value of tagName is the same as that of nodeName.
Example
HTML content
<span id="born">When I was born...</span>
JavaScript content
var span = document.getElementById("born");
console.log(span.tagName);
In XHTML (or any other XML format), "span" would be output. In HTML, "SPAN" would be output instead.
