Web/API/WindowOrWorkerGlobalScope/origin

This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

The origin read-only property of the WindowOrWorkerGlobalScope interface returns the origin of the global scope, serialized as a string.

Syntax

var myOrigin = self.origin; // or just origin

Value

A USVString.

Examples

Executed from inside a worker script, the following snippet will log the worker's global scope's origin to the console each time it receives a message

onmessage = function() {
  console.log(self.origin);
};

If the origin is not a scheme/host/port tuple (say you are trying to run it locally, i.e. via file:// URL), origin will return the string "null".
