HTMLImageElement.referrerPolicy

The HTMLImageElement.referrerPolicy property reflects the HTML referrerpolicy attribute of the <img> element defining which referrer is sent when fetching the resource.

Syntax

refStr = imgElt.referrerPolicy;
imgElt.referrerPolicy = refStr;

Values

A DOMString representing the referrer policy. Possible values are:

• "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.

Examples

var img = new Image();
img.src = 'img/logo.png'; 
img.referrerPolicy = 'origin';

var div = document.getElementById('divAround');
div.appendChild(img); // Fetch the image using the origin as the referrer
