The Attr.localName
read-only property returns the local part of the qualified name of an element.
Before DOM4 this API was defined within the {{domxref("Node")}} interface.
Syntax
name = attribute.localName
Return value
A {{domxref("DOMString")}} representing the local part of the attribute's qualified name.
Notes
The local name of an attribute is the part of the attribute's qualified name that comes after the colon. Qualified names are typically used in XML as part of the namespace(s) of the particular XML documents.
Note: In {{Gecko("1.9.2")}} and earlier, the property returns the upper-cased version of the local name for HTML attributes in HTML DOMs (as opposed to XHTML attributes in XML DOMs). In later versions, in compliance with HTML5, the property returns in the case of the internal DOM storage, which is lower case for both HTML attributes in HTML DOMs and XHTML attributes in XML DOMs.
