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; deprecated in
ECMAScript v3
Synopsis
unescape(s)Arguments
s
The string that is to be decoded or "unescaped."
Returns
A decoded copy of s.
Description
unescape( ) is a global function that decodes a
string encoded with escape( ). It decodes
s by finding and replacing character
sequences of the form
%xx and
%uxxxx (where
x represents a hexadecimal digit) with the
Unicode characters
\u00xx and
\uxxxx.
Although unescape( ) was standardized in the first
version of ECMAScript, it has been deprecated and removed from the
standard by ECMAScript v3. Implementations of ECMAScript are likely
to implement this function, but they are not required to. In
JavaScript 1.5 and JScript 5.5 and later, you should use
decodeURI( ) and decodeURIComponent(
) instead of unescape( ). See
escape( ) for more details and an example.
