How to get recaptcha value using js jquery?

Question

JavaScript

Let's say that I have recaptcha 2.0 and a form for submitting data on my site. After the user clicks on submit, the form is validated using jquery, after which, if the form is validated, an ajax request is made to the php file.

That's actually the problem. I need to use js jquery to get the recaptcha value received from the server.

Answer 1

What then is the point in the captcha, if the robot can get the value and substitute it in the form?
Captcha should be checked only on the server. Otherwise, it's all meaningless.
