//this is @Geordy's javascript portion modified according to jquery.validate
<script type="text/javascript">
$().ready(function() {
var demo1Call = 0;
var demo2Call = 0;
// validate and submit 1st form
$("#demo-form1").validate({
rules: {
pass: {
required: true,
pwcheck: true,
minlength: 5
},
},
messages: {
pass: {
required: "Please provide a password",
pwcheck: "<br />*Minimum length 8<br />*Maximum length 24<br />*Atleast a digit<br />*Atleast an upper case<br />*Atleast a lowercase<br />*Atleast a special character from these !@#$%",

function onSubmit1(token){

};
function onSubmit2(token){

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.
