This is an experimental technology
Check 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"
.
