HTMLAreaElement: port property

The port property of the HTMLAreaElement interface is a string containing the port number of the <area> element's href. If the port is the default for the protocol (80 for ws: and http:, 443 for wss: and https:, and 21 for ftp:), this property contains an empty string, "".

This property can be set to change the port of the URL. If the URL has no host or its scheme is file:, then setting this property has no effect. It also silently ignores invalid port numbers.

See URL.port for more information.

Value

A string.
