Automated Form Submission: A Guide to Automatically Sending the Form After Captcha Verification

I'm looking to incorporate ReCaptcha into my website in order to display additional data. My goal is to have the form automatically submitted once the ReCaptcha has been completed, eliminating the need for an extra submit button. However, I've encountered a challenge due to ReCaptcha loading its content within an iframe.

Currently, my form looks like this:

<form action="javascript:getInfo(grecaptcha.getResponse(widget1));" >
      <div id="captcha"></div>
      <br>
      <input type="submit" value="Submit">
</form>

Is there a way to set up an Event Listener on the ReCaptcha submit that would then trigger the submission of the outer form?

That technique seems quite intriguing as it could streamline the user experience by minimizing clicks and key strokes. To implement this, you can listen for a successful captcha response and then execute the desired action accordingly. Check out this example and accompanying documentation: https://developers.google.com/recaptcha/docs/display#example

var RC2KEY = 'sitekey';

function reCaptchaVerify(response) {
  if (response === document.querySelector('.g-recaptcha-response').value) {
    document.forms['form-name'].submit();
  }
}

function reCaptchaExpired() {
  /* handle expiration */
}

function reCaptchaCallback() {
  grecaptcha.render('id', {
    'sitekey': RC2KEY,
    'callback': reCaptchaVerify,
    'expired-callback': reCaptchaExpired
  });
}

<script src='https://www.google.com/recaptcha/api.js?onload=reCaptchaCallback&render=explicit'></script>

Instead of using ?, opt for #

The symbol ? is typically used to start query strings, but it can interfere with responses that have a method=GET. On the other hand, the anchor symbol # will work seamlessly in these situations.
