Ich verwende das Validate JQuery Plugin und Recaptcha für ein Kontaktformular und möchte wissen, wie ich überprüfen kann, ob der Code im Captcha korrekt ist, bevor das Formular gesendet wird, wenn keine Fehlermeldung gesendet wird, da im Moment alles validiert wird, außer ich habe ein eingefügt falscher code das formular wird trotzdem gesendet. Hier ist mein Code für jede Hilfe im Voraus

<script type="text/javascript">
             var RecaptchaOptions = {
                lang : 'en',
                theme : 'custom',
                custom_theme_widget: 'recaptcha_widget'
             };
            </script>

            <form id="contact" method="post" action="#">

                <fieldset>
                    <label for="name_contact">NAME</label>
                    <input type="text" class="input-xlarge" id="name_contact" name="name_contact" value="" placeholder="" minlength="2">

                    <label for="email_contact">EMAIL</label>
                    <input type="email" class="input-xlarge" id="email_contact" name="email_contact" value="" placeholder="">

                    <label for="telephone">CONTACT NUMBER</label>
                    <input type="tel" class="input-xlarge" id="telephone" name="telephone" placeholder="" value="" >

                    <label for="message">MESSAGE</label>
