Location: origin property

Note: This feature is available in Web Workers.

The origin read-only property of the Location interface is a string containing the Unicode serialization of the origin of the represented URL.

The exact structure varies depending on the type of URL:

  • For URL using the http: or https: schemes, the scheme followed by //, followed by the domain, followed by :, followed by the port (the default port, 80 and 443 respectively, if explicitly specified).
  • For URL using file: scheme, the value is browser dependent.
  • For URL using the blob: scheme, the origin of the URL following blob:. For example, blob:https://mozilla.org will have https://mozilla.org.
