The URL.origin read-only property returns 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: 此特性在 Web Worker 中可用。

语法:

string = URLObject.origin;

样例:

var result = new URL("blob:https://mozilla.org:443/").origin;
// Returns:'https://developer.mozilla.org:443'

[1] Though not grouped in a single abstract interface, this method is directly available on the interfaces that implement it, if this interface is supported.

[2] From Gecko 26 to Gecko 44, this property was on the URLUtils mixin. It has been moves either on the HTMLHyperlinkElementUtils mixin, or directly on the interface.

[3] Before Gecko 49, results for URL using the blob scheme incorrectly returned null.
