reCAPTCHA : Grey out Submit button until backend interaction is finished -

-

i've integrated recaptcha , working fine, except when users quick click submit button right after checking "i'm not robot" checkbox. takes quite time recaptcha register user action via ajax, , if click on submit quickly, g-recaptcha-response missing, , validation fails.

hence question: how grey out submit button until g-recaptcha-response value available?

    <form id="capform" action="/captchaverify" method="post">         <div class="g-recaptcha" data-sitekey="..."></div>         <p>         <input id="capsubmit" type="submit" value="submit">     </form>

i ended using data-callback attribute described in documentation:

<form action="/captchaverify" method="post">     <div class="g-recaptcha" data-sitekey="..." data-callback="capenable" data-expired-callback="capdisable"></div>     <p>     <input id="capsubmit" type="submit" value="submit"> </form>

javascript (mootools-based, general idea should clear):

function capenable() {     $('capsubmit').set('disabled', false); } function capdisable() {     $('capsubmit').set('disabled', true); } window.addevent('domready', function(){     capdisable(); });
