How can I make reCAPTCHA a required field?

Question

I\'m using Google reCAPTCHA and have been able to add the CAPTCHA component to my page inside a form. But when I submit the form there\'s no validation taking place to check

I find this very helpful:

You add a function to data-callback="recaptchaCallback" with this code:

var recaptchachecked=false; 
function recaptchaCallback() {
    recaptchachecked = true;
}

and a function were you return the value to use it in a other html-tag like this:

function isreCaptchaChecked()
{
    return recaptchachecked;
}

I hope this helps you.
