当我使用Happy.js提交表单时，如何显示消息？

Question

我试图在unHappy函数中包含一个条件;在表单处理过程中，我没有收到表示成功的消息！这是我的代码。

var dd= $.noConflict();

  dd(document).ready(function () {
    dd('.success').hide();
        dd('#frmContact').isHappy({
            fields: {
              // reference the field you're talking about, probably by `id`
              // but you could certainly do $('[name=name]') as well.
              '#yourName': {
                required: true,
                message: 'Might we inquire your name'
              },
              '#email': {
                required: true,
                message: 'How are we to reach you sans email??',
                test: happy.email // this can be *any* function that returns true or false
              },
              '#comments': {
                required: true,
                message: 'Please leave a message!',
              }
          },
          unHappy: function () {
            var yourName = dd('#yourName').val();
            var email = dd('#email').val();
            var comments = dd('#comments').val();
                if (yourName && email && comments == true){
                    dd('.success').show();
                            return;

            } 
        },
      });
  });
