Window: origin property

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

Value

A string.

Examples

Executed from inside window scope, the following snippet will log the document's global scope's origin to the console.

js
console.log(window.origin); // On this page returns 'https://developer.mozilla.org'

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".
