This article introduces the detailed code of the jQuery plug-in Validate to implement custom verification result styles. It is shared with everyone for your reference. The specific content is as follows

The effect is as follows:

Specific steps:

1. Introduce dependency packages

 <script src="../../scripts/jquery-1.3.1.js" type="text/javascript"></script>
 <script src="lib/jquery.validate.js" type="text/javascript"></script>

2. Add error style

 em.error {
 background:url("images/unchecked.gif") no-repeat 0px 0px;
 padding-left: 16px;
}
em.success {
 background:url("images/checked.gif") no-repeat 0px 0px;
 padding-left: 16px;
}

3. Customized prompt information

 messages: {
      username: {
        required: '请输入姓名',
        minlength: '请至少输入两个字符'
      },
      email: {
        required: '请输入电子邮件',
        email: '请检查电子邮件的格式'
      },
      url: '请检查网址的格式',
      comment: '请输入您的评论'
    },

4. Call error style or success style

 errorElement: "em", //可以用其他标签，记住把样式也对应修改
    success: function(label) {
      //label指向上面那个错误提示信息标签em
      label.text(" ")        //清空错误提示消息
        .addClass("success");  //加上自定义的success类
    }
