let referrerUrl = document.referrer; let referrerUrlMatch = referrerUrl.match(/^https?:\/\/www\.(venetian|palazzo)\.com(?!\/meetings(\/|$))/); let referrerName = referrerUrlMatch ? referrerUrlMatch : null;
At that point, referrerName is either “venetian", "palazzo", or null (if referrer URL was from neither of the two sites, or if the path started with “/meetings/“), and the referrerUrl can be used as needed.
Examples: "https://www.venetian.com/meetings” returns null
