This is my code so far:

<script type="text/javascript">

var widgetId1;
var onloadCallback = function() {

    widgetId1 = grecaptcha.render('le_captcha', {
      'sitekey' : 'xxx',
      'theme' : 'light'
    });
};


function check(){
    alert(grecaptcha.getResponse(widgetId1));
}

function executeMeAfterSuccessfullValidation(){
    alert('user passed');
}
</script>


<button onclick="check()">check if passed</button>

<div id="le_captcha"></div>

I want executeMeAfterSuccessfullValidation to be called after the user successfully validate.

There is nothing in their docs how to do that: https://developers.google.com/recaptcha/docs/display

But I've seen some websites doing it. How?

Thanks in advance

Maybe they are returning a promise? Try that? Or a callback parameter? – o elhajoui Nov 12 '18 at 19:43
The callback parameter is executed right after page load. What do you mean by "returning a promise" ? – Eduard Unruh Nov 12 '18 at 19:47
This is a promise https://developer.mozilla.org/nl/docs/Web/JavaScript/Reference/Global_Objects/Promise – o elhajoui Nov 12 '18 at 19:48
Ok but how could I use it on recaptcha? – Eduard Unruh Nov 12 '18 at 19:51
