title: How do i retrieve analytics.js utm_campaign value in JS?
body: <p>A client has a web form that would like to include (via hidden inputs) the campaign, referral, source and other UTM tags that are usually sent across by google analytics but since the upgrade to universal analytics i don't seem to be able to find them in the traditional __UTMZ cookie. The goal here is to get the data into the html inputs. Any suggestions on how to get the values via JS?</p>
