<script>
  function onSubmit(token) {
    alert('thanks ' + document.getElementById('field').value);
  }

  function validate(event) {
    event.preventDefault();
    if (!document.getElementById('field').value) {
      alert("You must add text to the required field");
    } else {
      grecaptcha.execute();
    }
  }

  function onload() {
    var element = document.getElementById('submit');
    element.onclick = validate;
  }
</script>
Before body tag close
<script>onload();</script>
