HTMLAnchorElement: protocol property

The protocol property of the HTMLAnchorElement interface is a string containing the protocol or scheme of the <area> element's href, including the final ":". 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 protocol of the URL. A ":" is appended to the provided string if not provided. The provided scheme has to be compatible with the rest of the URL to be considered valid.

See URL.protocol for more information.
