unescape()
Warning: Although unescape()
is not strictly deprecated
(as in "removed from the Web standards"), it is defined in
Annex B
of the ECMA-262 standard, whose introduction states:
… All of the language features and behaviors specified in this annex have one or more undesirable characteristics and in the absence of legacy usage would be removed from this specification. … … Programmers should not use or assume the existence of these features and behaviors when writing new ECMAScript code. …
The unescape()
function computes a new string in which
hexadecimal escape sequences are replaced with the character that it represents. The
escape sequences might be introduced by a function like escape
. Usually,
decodeURI
or decodeURIComponent
are preferred over
unescape
.
Note: Do not use unescape
to decode URIs,
use decodeURI
instead.
