MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

Document.origin

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

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'
