The referrer
read-only property of the Request
interface is set by the user agent to be the referrer of the Request. (e.g., client
, no-referrer
, or a URL.)
Note: If referrer
's value is no-referrer
, it returns an empty string.
Syntax
var myReferrer = request.referrer;
Value
A DOMString
representing the request's referrer.
Example
In the following snippet, we create a new request using the Request.Request()
constructor (for an image file in the same directory as the script), then save the request referrer in a variable:
var myRequest = new Request('flowers.jpg'); var myReferrer = myRequest.referrer; // returns "about:client" by default
