我在注册表格中添加了reCAPTCHA，并且在测试页面时，我注意到我仍然可以注册新帐户而无需使用reCAPTCHA进行验证。当我将其中一个文本框留为空白时，我会收到“请确认您是人类”。当用户填写表单而忘记验证时，该消息应该会出现。如果堆栈溢出和其他网站提供的语句，我尝试了许多不同的方法，但问题仍然没有解决。我还尝试用“方法”和“动作”弄乱我的表单。
这是我的注册表

您需要将验证码字段本身设置为必填字段，默认情况下不是。
您可以尝试这样的事情：
<script type="text/javascript">
window.onload = function() {
var $recaptcha = document.querySelector('#g-recaptcha-response');
if ($recaptcha) {
$recaptcha.setAttribute("required", "required");
}
};
</script>
感谢您的回复，香港专业教育学院尝试过此
window.onload = function（）{var $ recaptcha = document.querySelector（'＃g-recaptcha-response'）;
if ($recaptcha) {
$recaptcha.setAttribute('#free_play_form_button').click()
}
};
但表格未回应
正在使用篡改猴子，我是否添加了正确的篡改方法？
