The escape()
function computes a new string in which certain characters have been replaced by a hexadecimal escape sequence.
escape(str)
str
A new string in which certain characters have been escaped.
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.
escape('abc123'); // "abc123" escape('äöü'); // "%E4%F6%FC" escape('ć'); // "%u0107" // special characters escape('@*_+-./'); // "@*_+-./"
