Support for display reCAPTCHA from AJAX API

[reypm]

I'm just wondering, since I didn't see nothing at config level, if this bundle supports for display reCAPTCHA from AJAX API as explained here if it's supported any example around configuration to take care?

You are right. The bundle does not handle reCaptcha loading by js (so by definition, ajax too). I made a pull request to fix this bug.

You can use this genemu_recaptcha_javascript block in a custom template form file until the pull request will be merge.

{% block genemu_recaptcha_javascript %}
{% spaceless %}
    <script type="text/javascript" src="{{ asset("https://www.google.com/recaptcha/api/js/recaptcha_ajax.js") }}"></script>
    <script type="text/javascript">
        function genemu_recaptcha_load()
        {
            Recaptcha.create('{{ public_key }}', '{{ id }}_div', {{ configs|json_encode|raw }});
        }

        if (window.addEventListener) {
            window.addEventListener('load', genemu_recaptcha_load, false);
        } else if (window.attachEvent) {
            window.attachEvent('onload', genemu_recaptcha_load);
        } else {
            window.onload = genemu_recaptcha_load;
        }
    </script>
{% endspaceless %}
{% endblock genemu_recaptcha_javascript %}

Sorry for my ignorance, that code give me an error Variable "public_key" does not exist in blablabla.html.twig in line where this is Recaptcha.create('{{ public_key }}', '{{ id }}_div', {{ configs|json_encode|raw }});

how can I fix that?
