HTMLAnchorElement.referrerPolicy

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTMLAnchorElement.referrerPolicy property reflect the HTML referrerpolicy attribute of the <a> element defining which referrer is sent when fetching the resource.

Syntax

refStr = anchorElt.referrerPolicy;
anchorElt.referrerPolicy = refStr;

Value

A DOMString; one of the following:

no-referrer: The Referer header will be omitted entirely. No referrer information is sent along with requests.
no-referrer-when-downgrade: The URL is sent as a referrer when the protocol security level stays the same (e.g.HTTP→HTTP, HTTPS→HTTPS), but isn't sent to a less secure destination (e.g. HTTPS→HTTP).
origin: Only send the origin of the document as the referrer in all cases. The document https://example.com/page.html will send the referrer https://example.com/.
origin-when-cross-origin: Send a full URL when performing a same-origin request, but only send the origin of the document for other cases.
same-origin: A referrer will be sent for same-site origins, but cross-origin requests will contain no referrer information.
strict-origin: Only send the origin of the document as the referrer when the protocol security level stays the same (e.g. HTTPS→HTTPS), but don't send it to a less secure destination (e.g. HTTPS→HTTP).
strict-origin-when-cross-origin (default): This is the user agent's default behavior if no policy is specified. Send a full URL when performing a same-origin request, only send the origin when the protocol security level stays the same (e.g. HTTPS→HTTPS), and send no header to a less secure destination (e.g. HTTPS→HTTP).
unsafe-url: Send a full URL when performing a same-origin or cross-origin request. This policy will leak origins and paths from TLS-protected resources to insecure origins. Carefully consider the impact of this setting.

Examples

var elt = document.createElement("a");
var linkText = document.createTextNode("My link");
elt.appendChild(linkText);
elt.href = "https://developer.mozilla.org/en-US/";
elt.referrerPolicy = "no-referrer";

var div = document.getElementById("divAround");
div.appendChild(elt); // When clicked, the link will not send a referrer header.
