I am using recaptcha with my laravel application.

I just want to check recaptcha's response on form submit using jquery and stop user by alert that pleade validate captcha.

but , I could not stop form submission even if captcha is not filled.

here is my code.

 $('#payuForm').on('submit', function (e) {



                    var response = grecaptcha.getResponse();



                    if(response.length == 0 ||  response == '' || response ===false ) {

                        alert('Please validate captcha.');

                        e.preventDefault();

                    }

                });







<div class=captcha>

 {{ View::make('recaptcha::display') }}

</div>

I am getting this error in browser console , and form gets submit.

Error: ReCAPTCHA placeholder element must be empty
