escape()
The deprecated escape()
function computes a new string in which certain characters have been replaced by a hexadecimal escape sequence. Use encodeURI
or encodeURIComponent
instead.
Syntax
escape(str)
Parameters
str
- A string to be encoded.
Return value
A new string in which certain characters have been escaped.
Description
The escape
function is a property of the global object. Special characters are encoded with the exception of: @*_+-./
The hexadecimal form for characters, whose code unit value is 0xFF or less, is a two-digit escape sequence: %xx. For characters with a greater code unit, the four-digit format %uxxxx is used.
Examples
escape("abc123"); // "abc123" escape("äöü"); // "%E4%F6%FC" escape("ć"); // "%u0107" // special characters escape("@*_+-./"); // "@*_+-./"
