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 1.0; JScript 1.0, ECMAScript v1
Synopsis
string.charAt(n)Arguments
n
The index of the character that should be returned from
string.
Returns
The nth character of
string.
Description
String.charAt( ) returns the
nth character of the string
string. The first character of the string
is numbered 0. If n is not between 0 and
string.length-1, this method returns an
empty string. Note that JavaScript does not have a character data
type that is distinct from the string type, so the returned character
is a string of length 1.
