最简单、最便捷，提示消息使用jQuery.Validate的内置的消息（自定义扩展验证规则也属于此项），但是由于是以样式名的方式进行验证，导致了日后修改必须找到相应的input对象，同时无法使用高级验证规则。
（2）在input对象中书写class样式，只不过书写的方式改为了JSON格式，但是这种方式提供了自定义验证消息的支持：
如<input type=”text”#aspnetform").validate({
rules: {
name: "required",
email: {
required: true,
email: true
}
})
})
很好的解决了HTML和验证规则的分离，就是书写较为麻烦，需要单独写JS脚本，但好处是可以统一验证规范，将每个页面的验证规则都写在头部的脚本中，方便日后维护。
