unescape

The deprecated 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. Because unescape is deprecated, use decodeURI or decodeURIComponent instead.

Note: Do not use unescape to decode URIs, use decodeURI instead.

Syntax

unescape(str)

Parameters

str: A string to be decoded.

Return value

A new string in which certain characters have been unescaped.

Description

The unescape function is a property of the global object.

Examples

unescape('abc123');     // "abc123"
unescape('%E4%F6%FC');  // "äöü"
unescape('%u0107');     // "ć"
