escape Function (JavaScript)

Encodes strings so they can be read on all computers. Deprecated.

Syntax

escape(charString)   

Remarks

The required charString argument is any String object or literal to be encoded.

The escape function returns a string value (in Unicode format) that contains the contents of charstring. All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding, where xx is equivalent to the hexadecimal number representing the character. For example, a space is returned as "%20."

Characters with a value greater than 255 are stored using the %u xxxx format.

Note

The escape function should not be used to encode Uniform Resource Identifiers (URI). Use encodeURI and encodeURIComponent functions instead.
