HTMLAreaElement: origin property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.
The origin read-only property of the HTMLAreaElement interface returns a string containing the Unicode serialization of the origin of the <area> element's href.
The exact structure varies depending on the type of URL:
- For URLs using the
ftp:, http:, https:, ws:, and wss: schemes, the protocol followed by //, followed by the host. Same as host, the port is only included if it's not the default for the protocol.
- For URLs using
file: scheme, the value is browser dependent.
- For URLs using the
blob: scheme, the origin of the URL following blob:, but only if that URL uses the http:, https:, or file: scheme. For example, blob:https://mozilla.org will have https://mozilla.org.
For all other cases, the string "null" is returned.
See URL.origin for more information.
