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
<element onhelp="handler" ... >element.onhelp
Description
The onhelp property of
element specifies an event handler
function that is invoked when the user presses the F1 key while
element has keyboard focus.
The initial value of this property is a function that contains the
JavaScript statements specified by the onhelp
attribute of the HTML tag that defined the element. When an event
handler function is defined by an HTML attribute, it is executed in
the scope of element rather than in the
scope of the containing window.
After the onhelp handler function is invoked,
Internet Explorer 4 displays the built-in help window.
