HTML | DOM referrer Property

The DOM referrer property in HTML is used to return the URI of the page that linked to the current page. If the user navigates to the page directly or through a bookmark, then this value is an empty string.
Syntax:

document.referrer

Return Value: A String, representing the URL of the document that loaded the current document. Returns the entire URL, including the protocol (like http://). If the current document was not opened through a link (for example, through a bookmark), an empty string is returned.
