Or anyone please suggest a working doc for multiple forms?

    <script type="text/javascript">

    $().ready(function() {
    var demo1Call = 0;
    var demo2Call = 0;

        // validate and submit 1st form
        $("#demo-form1").validate({
            rules: {

                  pass: {

I used Unofficial Google Invisible reCAPTCHA PHP library in this program and you can download it from https://github.com/geordyjames/google-Invisible-reCAPTCHA . If this method doesn't work for you please comment below.
