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.

Synopsis
boolean hasAttribute(String name);
Arguments
name
The name of the desired attribute.
Returns
true if this element has a specified or default
value for the named attribute, and false
otherwise.
Description
This method determines whether an element has an attribute with the
specified name, but does not return the value of that attribute. Note
that hasAttribute( ) returns
true if the named attribute is explicitly
specified in the document and also if the named attribute has a
default value specified by the document type.
