JavaScript: Node Name
node.nodeName
-
Return the node's (tag) name (a string), if the node is a element node (
nodeType
is 1). If it's a text node, the value is"#text"
.
- For HTML document, the return value is usually all UPPER CASE. (regardless what's in the file.)
- For XML/XHTML, it is always lowercase (because XML allow just lowercase.) However, there are edge cases, when a DOM element is imported from htm/html5/xml, or when older browser encounters a tag it doesn't know.
[see HTML/CSS Case Sensitivity]
You can use str.toLowerCase()
to convert it.
// first paragraph document.getElementsByTagName("p")[0].nodeName // "P" // first paragraph's content document.getElementsByTagName("p")[0].childNodes[0].nodeName // "#text"
As of 2012-04-29, this works in all major browsers.
