Google Recaptcha enables disabled submit button
Question
I'm using reCaptcha v2 invisible . I have a simple form with a disabled submit button. Google reCAPTCHA is enabling my disabled button.
<script src="https://www.google.com/recaptcha/api.js"></script>
<form action="/action_page.php" id="referral-form">
First name:
<br>
<input type="text" name="firstname">
<br>
Last name:
<br>
<input type="text" name="lastname">
<br>
<input type="submit" id="form-submit-btn" disabled="disabled" class="g-recaptcha" data-callback='onSubmit' data-sitekey="***************" value="Submit">
</form>
function onSubmit() {
if (grecaptcha.getResponse() !== "") {
$('#referral-form').submit();
}
grecaptcha.reset();
}
When I remove class="g-recaptcha" the button is properly disabled.

As I told in my comment above you could use a callback when the Invisible Recaptcha is rendered.
Try this code out and let me know if it worked:
<!doctype html>
<html>
<head>
<script>
var onSubmit = function(token) {
console.log(token);
// You can check token here and decide what to do
};
var onloadCallback = function() {
grecaptcha.render('form-submit-btn', {
'sitekey' : '***************',
'callback' : onSubmit
});
document.getElementById('form-submit-btn').disabled = true;
};
/////
// code to enable your button when you have content in the inputs
/////
</script>
</head>
<body>
<form action="/action_page.php" id="referral-form">
First name:
<br>
<input type="text" name="firstname">
<br>
Last name:
<br>
<input type="text" name="lastname">
<br>
<input type="submit" id="form-submit-btn" class="g-recaptcha" value="Submit">
</form>
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit" async defer></script>
</body>
</html>
I based this example on your code andthis example in Google Recaptcha's documentation.

为了解决这个问题，我升级到 reCaptcha v3，非常容易集成，现在我将提交从 <input type="submit" 更改为 ...。结果是表单现在可以完美运行。
