escape()

The escape() function computes a new string in which certain characters have been replaced by a hexadecimal escape sequence.

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('@*_+-./');    // "@*_+-./"
