HTMLAnchorElement: 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 HTMLAnchorElement interface is a string containing the port number of the URL, or the empty string if the port is the default for the protocol.

Note: If the HTMLAnchorElement object refers to a URL that doesn't contain an explicit port number (e.g., https://localhost) or contains a port number that's the default port number corresponding to the protocol part of the URL (e.g., https://localhost:443), then the port property will be the empty string: ''.

Value

A string.
