HTMLImageElement.referrerPolicy 反映了 <img> 元素的HTML属性 referrerpolicy 的定义,这个属性定义了<img> 元素在获取资源时的引用方式。



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

  • "no-referrer" 表示HTTP头部信息将不会发送 referrer
  • "origin" 表示 referrer 只包含策略、主机名、端口等页面源的信息。
  • "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 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
