Location: port property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

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.
