个人体验recaptcha v2也是比较烦，有时同一ip触犯到规则了，验证码会变得很烦，不是很方便。v3就解决了这个烦恼，于是我又写了一套完整的v3 demo
想看v2的可以点这里
废话不多说，上源码

event.preventDefault();
grecaptcha.ready(function () {
grecaptcha.execute('【同上，公钥】', {action: 'UnionLogin'}).then(function (token) {
dataForm = $('#dataForm')
dataForm.prepend('<input type="hidden" name="token" value="' + token + '">');
dataForm.prepend('<input type="hidden" name="action" value="UnionLogin">');
dataForm.unbind('submit').submit();
});
});
