Document.origin - Web APIs 编辑

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Use self.origin instead.

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

Syntax

var origin = document.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'
