    GA event tracking for onSuccess

    Thomas Rosen

      I am trying to figure out what's wrong with my landing page. I am trying to keep the on-page thank you message and send a GA event. I have the thank you working as expected, but the GA event is not firing.


      Here is the code that I'm using:


      <script src="//app-ab14.marketo.com/js/forms2/js/forms2.js"></script>


      MktoForms2.whenReady(function (form){

      //Add an onSuccess handler

      form.onSuccess(function(values, followUpUrl){

      //GA event trigger

      if ( 'YES' == '${z-TriggerGAEvent}') {



      //get the form's jQuery element and hide it


          document.getElementById('confirmform').style.visibility = 'visible';

          //return false to prevent the submission handler from taking the lead to the follow up url.

          return false;





      The landing page lives here.


      Any suggestions are much appreciated.

          The reason this isn't working doesn't have to do with Marketo. It's because you're using the gtag.js library, not the core GA library. The equivalent gtag syntax is:


          gtag('event', 'beacon-submit', { 
            event_category: 'form', 
            event_label: 'marketo' 


          In the future, please use the Advanced Editor's syntax highlighter for JS, keeps me saner:
