HTMLAreaElement: protocol 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 protocol property of the HTMLAreaElement 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.

Value

A string.
