javascript - Recaptcha 2 how to check if user cancels puzzle -




how detect if user cancelling recaptcha puzzle: enter image description here

it possible click outside dialog box , close dialog. however, there doesn't seem callback action. necessary return user previous action.

we initializing recaptcha 2 programmatically this:

grecaptcha.render('grecaptchacontainer', {   'sitekey': our_site_key,   'callback': grecaptcha_responds,   'expired-callback': grecaptcha_expires, }); 

the callback function called, no problem.

the expired-callback function never called. figured function called when user cancels/waits long. not case.

could not find in docs or on web. takers?
