提交仅适用于第二次点击

Question

I have a form with a verification through Google reCaptcha. But now I have to click the submit button twice. I can't find the reason.

My form is build like this (Smarty):

<form method="post" id="form">
   <input type="hidden" name="action" value="misdaden">
     <table>
        {foreach from=$misdaden item=item}
           <tr>
                <td class="coll">{$item['id']}</td>
                <td class="coll">{$item['name']}</td>
                <td class="coll">{$item['minmoney']}</td>
                <td class="coll">{$item['maxmoney']}</td>
                <td class="coll">{$item['difficulty']}</td>
                <td class="coll">{$item['percentage']}%</td>
                <td class="coll"><input type="radio" style="width:20px;" name="value" value={$item['id']} /></td>
           </tr>
        {/foreach}
    </table>
    <input type="submit" value="Misdaad plegen!" name="submit" class="submit" />
    <!--input class="button good large" name="submit" type="submit" value="Pleeg misdaad!"-->
</form>

My script is (JQuery):

$('#form').submit(function(e) {
    e.preventDefault();
    grecaptcha.ready(function() {
    grecaptcha.execute('6LesiMAUAAAAAAJ8G94kKbXxJj62_U2ajn-dzJzF', {action:'misdaden'})
              .then(function(token) {
                    $('#form').prepend('<input type="hidden" name="token" value="'+ token +'">');
                    $('#form').unbind('submit').submit();
                });
    });
});

I'm probably missing something obvious, but what?

Answer 1

In the jquery script, you are unbinding the submit event handler for form on execution of captcha which is not required. Just submit the form, see below

$(document).ready(function() {
    grecaptcha.ready(function() {
    grecaptcha.execute('6LesiMAUAAAAAAJ8G94kKbXxJj62_U2ajn-dzJzF', {action:'misdaden'})
              .then(function(token) {
                    $('#form').prepend('<input type="hidden" name="token" value="'+ token +'">');
                    $('#form').submit();
                });
    });
});
