Recibo el error titular cuando intento llamar alvalidate() Funcionar en mi formulario. Toda la investigación que he hecho dice "asegúrate de que lo llamas", sin embargo, estoy 95% seguro de que estoy de acuerdo con esto:

<script type="text/javascript" src="http://test.elitetradersgroup.com.au/wp-content/plugins/a-test/jquery.validate.min.js?ver=3.3.2"></script>
<script type="text/javascript" src="http://test.elitetradersgroup.com.au/wp-content/plugins/a-test/additional-methods.min.js?ver=3.3.2"></script>

Cuando hago clic en ellos en las herramientas de desarrollo de Chromes, aparecen los archivos de complementos, lo que me lleva a creer que están incluidos. Se les llama después de jQuery, así que dudo mucho que sea eso.

La forma se ve así:

<form action="http://test.elitetradersgroup.com.au/broker-tools/amazon-upload/" method="post" class="upload" enctype="multipart/form-data">

    <input type="hidden" value="elitetradersgroup" name="amazon_bucket">

<input type="hidden" name="uid" value="p16ubcu16t1gus18ls12g79ls1"></form>

Y la llamada así:

<script type="text/javascript">
    function broker_validate() {
        jQuery("form").validate({ //line where the error pops up in console
            rules: {
                theTitle: {
                    required: true
                },
            messages: {
                theTitle: {
                    required: "The email needs a title"
                }
            }
            }
        })

        if (jQuery("form").valid()) {
            jQuery("#validate").hide();
            jQuery("#juploader").show();
        }

    };

</script>

Esto me ha dejado perplejo, estoy seguro de que es una pequeña sintaxis estúpida o un error de prioridad. ¿Alguien con ojos nuevos puede verlo?

Para su información, el sitio está ejecutando wordpress, como podrá ver si jQuery se extrae de un archivo de complementos.

En respuesta a un comentario aquí está la salida de la consola de Chrome deconsole.log(jQuery("form"));:

E.fn.E.init
    0: HTMLFormElement
    length: 1
    prevObject: E.fn.E.init
    __proto__: Object
