Location: port property
The port property of the Location interface is a string containing the port number of the location's URL. 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.
