The attributionSrc property of the HTMLImageElement interface that you want the browser to send an Attribution-Reporting-Eligible header along with the image request. It reflects the <img> element's attributionsrc content attribute.
See the Attribution Reporting API for more details.
Value
A string that is either empty or a space-separated list of URLs. For the interpretation of this attribute, see the HTML <img> reference.
Examples
Setting an empty attributionSrc
<img src="advertising-image.png" />
const imgElem = document.querySelector("img");
imgElem.attributionSrc = "";
Setting an attributionSrc containing URLs
<img src="advertising-image.png" />
// encode the URLs in case they contain special characters
// such as '=' that would be improperly parsed.
const encodedUrlA = encodeURIComponent("https://a.example/register-source");
const encodedUrlB = encodeURIComponent("https://b.example/register-source");
const imgElem = document.querySelector("img");
imgElem.attributionSrc = `${encodedUrlA} ${encodedUrlB}`;
