Deprecated
This feature has been removed from the Web. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
Summary
The deprecated escape()
method computes a new string in which certain characters have been replaced by a hexadecimal escape sequence.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.
Description
The escape
function is a property of the global object. Special characteres 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("@*_+-./"); // "@*_+-./"
