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
JavaScript 1.1; JScript 2.0; ECMAScript v1
Synopsis
function.length
Description
The length property of a function specifies the
number of named arguments declared when the function was defined. The
function may actually be invoked with more than or fewer than this
number of arguments. Don't confuse this property of a Function
object with the length property of the Arguments
object which specifies the number of arguments actually passed to the
function. See Arguments.length for an example.
