how to require javascript?

i’ve found another captcha plugin https://www.ads-software.com/plugins/google-captcha/
that almost works: while login/comment forms fail when recaptcha doesn’t load (and gotta work on the failure message: “Authentication failed.” needs more explaination, like “javascript necessary”;-) registration blows right thru without recaptcha, even tho i have “keep submit button disabled until reCaptcha is loaded” enabled…

well i give up…https://www.ads-software.com/plugins/google-captcha/ can inject css/js to show/hide elements, but since the captcha isn’t loaded before the js runs, it never sees it:-\

and <noscript> is useless because it only requires a single js to be enabled…

Not sure if it would be able to do that or not, but filter hooks you could possibly use would be:

• wpmem_register_form_before
• wpmem_register_form

Of it it were a case of adding a class to the button for the js to find it, you could change/add the class with wpmem_register_form_args.
