{{ApiRef("HTML DOM")}}
The port property of the {{domxref("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 {{domxref("HTMLAnchorElement.host", "host")}} or its scheme is file:, then setting this property has no effect. It also silently ignores invalid port numbers.
See {{domxref("URL.port")}} for more information.
