This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.
Availability
DOM Level 2 Core
Synopsis
boolean hasAttributeNS(String namespaceURI,
String localName);
Arguments
namespaceURI
The unique namespace identifier for the attribute, or
null for no namespace.
localName
The name of the attribute within the specified namespace.
Returns
true if this element has an explicitly specified
value or a default value for the specified attribute;
false otherwise.
Description
This method works like hasAttribute( ), except
that the attribute to be checked for is specified by namespace and
name. This method is useful only with XML documents that use
namespaces.
