Location: origin

The origin read-only property of the Location interface is a USVString containing the Unicode serialization of the origin of the represented URL; that is:

  • for URL using the http or https, the scheme followed by '://', followed by the domain, followed by ':', followed by the port (the default port, 80 and 443 respectively, if explicitely specified);
  • for URL using file: scheme, the value is browser dependant;
  • for URL using the blob: scheme, the origin of the URL following blob:. E.g "blob:https://mozilla.org" will have "https://mozilla.org".
Note: This feature is available in Web Workers.

Syntax

string = object.origin;

Examples

// On this page, returns the origin
var result = window.location.origin; // Returns:'https://developer.mozilla.org'
