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.
