getAttributeNS method

String? getAttributeNS(
  1. String? namespace,
  2. String localName
)

The getAttributeNS() method of the Element interface returns the string value of the attribute with the specified namespace and name. If the named attribute does not exist, the value returned will either be null or "" (the empty string); see Notes for details.

If you are working with HTML documents and you don't need to specify the requested attribute as being part of a specific namespace, use the Element.getAttribute method instead.

Implementation

external String? getAttributeNS(
  String? namespace,
  String localName,
);
