使用jquery验证插件的成功消息

Question

我有this网页，我正在使用jQuery验证插件。错误消息没问题，它们正确显示image（error.png）。但我有图像的问题，信号，输入是好的。我尝试用这段代码制作它，但我失败了。

success: function(label) {
    var messages = new Array(
        "Looks good!",
        "You got it!",
        "Ok!"
    );

    var num = Math.floor(Math.random()*3); 

    label.text(messages[num]).addClass("success");
}

所以我需要你的帮助，如何添加课程“成功”。

我的jQuery：

$(document).ready(function () {

$('#myform').validate({ // initialize the plugin
    rules: {
        email: {
            required: true,
            email: true
        },
        phone: {
            required: true,
            intlphone: true
        },
        jmeno: {
            required: true,
            tagcheck: true
        },
        psc: {
            required: true,
            psc: true
        },
        ulice: {
            required: true,
            minlength: 3
        },
        mesto: {
            required: true,
            minlength: 3
        }
    },
    errorElement: "p",
    messages: {
      email: "<img src='images/error.png' alt='error'>",
      phone: "<img src='images/error.png' alt='error'>",
      jmeno: "<img src='images/error.png' alt='error'>",
      psc: "<img src='images/error.png' alt='error'>",
      ulice: "<img src='images/error.png' alt='error'>",
      mesto: "<img src='images/error.png' alt='error'>"
    },
    submitHandler: function (form) { // for demo
        alert('valid form submitted'); // for demo
        return false; // for demo
    },
});

});

我的CSS和HTML：

<style type="text/css">
      .successhiden {
        display:none;
      }
      .success{
        display:block!important;
      }
      </style>
          <div class="radek">
              <label>Kontaktní email:</label><input type="email" name="email" class="pw">
              <img src='images/done.png' alt='done' id="successMessage" style="display:none;" class="successhiden">
          </div> 
          <div class="radek">
              <label>Telefon:</label><input type="text" name="phone" class="pw">
              <img src='images/done.png' alt='done' id="successMessage" style="display:none;" class="successhiden">

          <div class="radek">
