document.origin

The Document.origin read-only property returns the document's origin. In most cases, this property is equivalent to document.defaultView.location.origin.

Examples

var origin = document.origin; 
// On this page, returns:'https://developer.mozilla.org'

var origin = document.origin; 
// On "about:blank", returns:'null'

var origin = document.origin; 
// On "data:text/html,<b>foo</b>", returns:'null'
