How to correctly set the goal of a metric / analytics using js?

Question

JavaScript

Tell me please. How to set a goal so that it works.
The site has feedback forms, I'm trying to add onsubmit through the script, but for some reason it is not attached to the form. On the button via onclick is not an option, since there are no unique classes

<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#yw1').attr("onsubmit","yaCounter46372170.reachGoal('zakazbistr'); gtag('send', 'event', { 'event_category': 'sub', 'event_action': 'btnsub'}); return true;");
});
</script>

Answer 1

Why are you using the .attr() method? It's easier to do this:

jQuery(document).ready(function(){
  jQuery('#yw1').on("submit", function() {
    yaCounter46372170.reachGoal('zakazbistr');
    gtag('send', 'event', { 'event_category': 'sub', 'event_action': 'btnsub'});
  });
});
