This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.
refStr = anchorElt.referrerPolicy; anchorElt.referrerPolicy = refStr;
"no-referrer"meaning that the
Referer:HTTP header will not be sent.
"origin"meaning that the referrer will be the origin of the page, that is roughly the scheme, the host and the port.
"unsafe-url"meaning that the referrer will include the origin and the path (but not the fragment, password, or username). This case is unsafe as it can leak path information that has been concealed to third-party by using TLS.
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.
