I have an event snippet for log sign-ups in my ruby on rails project. When a user creates an account (click on sign up) it will load the javascript with the snippet, but I want to load the javascript only when the user makes the account successful

Script:

<script>
 function googleAnalytics() {
   console.log("google analytics snippet loaded");
 }
</script>

html.erb file:

<%= button_tag f.submit t('sign_up'), type: 'button', onclick: 'googleAnalytics()', class: 'btn w-full' %>
