unescape Function (JavaScript)

Decodes String objects encoded with the escape function. Deprecated.

Syntax

unescape(charString)   

Remarks

The required charString argument is a String object or literal to be decoded.

The unescape function returns a string value that contains the contents of charstring. All characters encoded with the %xx hexadecimal form are replaced by their ASCII character set equivalents.

Characters encoded in %u xxxx format (Unicode characters) are replaced with the Unicode character with hexadecimal encoding xxxx.

Note

The unescape function should not be used to decode Uniform Resource Identifiers (URI). Use decodeURI and decodeURIComponent functions instead.
