所以这段代码看起来不错，我似乎看不出错误来自哪里。它被正确包装在 $(document).ready(function(){.
$("#signup-form").validate({
rules: {
firstname: 'required',
signup-email: 'required',
signup-password: 'required',
signup-password-v: 'required'
},
messages: {
firstname: 'Your firstname is required!',
signup-email: 'Your email is required!',
signup-password: 'A password is required!',
signup-password-v: 'Please verify your password!'
}
});
我在 html head 标签中的 jquery 库之后调用 jquery.validate，所以有什么想法吗？

最佳答案
属性名称中不能包含破折号:
signup-email: 'Your email is required!',
不过，我认为您可以将这些属性用引号引起来，并获得您想要的效果:
'signup-email': 'Your email is required!',
