你好我正在使用jquery验证插件，它没有显示任何消息

我的 javascript 是

<script type="text/javascript">

         $(document).ready(function () {

             $('#mainform').validate({
                 rules: {
                     DishNameTextBox: { required: true, minlength: 2 },
                     DishDescriptionTextBox: { required: true }
                 },
                 highlight: function (label) {
                     alert('hi');
                     $(label).closest('.control-group').addClass('error');
                 },
                 success: function (label) {

                     label
                         .text('OK!').addClass('valid')
                         .closest('.control-group').addClass('success');
                 }
             });
         });
     </script>

我正在使用母版页，它的 HTML 如下

<head runat="server">
    <title></title>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
    <script>        window.jQuery || document.write('<script src="js/vendor/jquery-1.8.2.min.js"><\/script>')</script>
     <script src="js/jquery.validate.js" type="text/javascript"></script>
    <script src="js/vendor/bootstrap.min.js"></script>
    <script src="js/twitter-bootstrap-hover-dropdown.min.js" type="text/javascript"></script>
    <script src="js/vendor/modernizr-2.6.1-respond-1.1.0.min.js"></script>
    <script src="js/main.js"></script>
    <link href="css/bootstrapNew.css" rel="stylesheet" type="text/css" />
    <link rel="stylesheet" href="css/main.css">
    <link href="css/Custom.css" rel="stylesheet" type="text/css" />
    <link href="themes/default/default.css" rel="stylesheet" type="text/css" />
    <!--[if lt IE 9]>
    <script src="//html5shim.googlecode.com/svn/trunk/html5.js"></script>
  <![endif]-->
</head>
<body>
    <form runat="server" id="mainform">
    <uc1:TopNavigationUserControl ID="TopNavigationUserControl1" runat="server" />
    <asp:ContentPlaceHolder ID="ContentPlaceHolderMain" runat="server">
    </asp:ContentPlaceHolder>
    </form>
</body>
</html>

我不确定我要去哪里错了。

请帮忙，因为我已经浪费了 5 个小时来调试这个问题，但没有任何运气.. :(

好的..这是我的观点。

对于任何正在阅读本文的人

1) ClientModeID = "Static" 将使您的控件 ID 静态，但名称不会[如果您使用母版页，名称会有所不同]

2) Jquery 验证插件适用于name 和 id 并且两者应该相同。

我希望它会节省一些人的时间。

您需要找出在浏览器中呈现的字段名称——我敢打赌它们不叫 DishNameTextBox 和 DishDescriptionTextBox。

他们更有可能被称为

ctl00$ctl00$ContentPlaceHolderMain$DishNameTextBox

这就是 asp.net 呈现母版页中包含的表单字段的方式。右键单击 chrome/firefox 中的字段和“检查元素”，或查看源代码并搜索 DishNameTextBox。

编辑

你可以看到你的输入有两个名字 jQuery validate 不能很好地配合这个。也许这与 'ClientIDMode="Static"' 我不知道，但你需要解决这个问题

<input name="ctl00$ContentPlaceHolderMain$DishNameTextBox" type="text" id="DishNameTextBox" name="DishNameTextBox" style="width:300px;" />

获取 jquery 在验证中使用的控件名称，例如

<%= DishDescriptionTextBox.UniqueID %> 将产生 ctl00$ContentPlaceHolderMain$DishDescriptionTextBox

使用唯一标识

你可以试试这个

 $("#aspnetForm").validate({
        rules: {
            <%= txtfname.UniqueID %>: {
                required: true
            }
        }
    });
