hasAttributeNS method
The hasAttributeNS()
method of the Element
interface returns a
boolean value indicating whether the current element has the specified
attribute with the specified namespace.
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.hasAttribute
method instead.
Implementation
external bool hasAttributeNS(
String? namespace,
String localName,
);
