I am using recaptcha v2



I am getting the following error occasionally (sometimes i don't get error and sometimes i do get it)



Uncaught ReferenceError: grecaptcha is not defined


It seems because of the internal http request. that takes some time to get another js recaptcha__en.js. Meanwhile actual rendering code of grecaptcha executes.



So what is the standard solution to avoid this issue.?



PS : of course i am looking for some solution other than setTimeout

Recaptcha has a onload callback that will run once recaptcha is loaded. Place your code inside that callback function.



https://developers.google.com/recaptcha/docs/display



<script>

    function onloadCallback() {

        /* Place your recaptcha rendering code here */

    }

</script>

<script src=https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit></script>
