Question

好的，我正在使用jQuery验证插件来检查简单表单上的错误。除错误放置外，一切正常。我试图在包含错误的INPUT之后将我的错误消息放入SPAN元素。出于某种原因，下面的代码将错误消息放在似乎是一个全新的LABEL元素中。知道我在这里做错了吗？

我的HTML

    <form action="" id="contact" method="POST">
       <p>
         <label for="name">Name:</label>
         <input type="text" name="name" id="name" class="text proper"/><span class="errMsg"></span>
       </p>
       <p>
         <label for="email">* Email:</label>
         <input type="text" name="email" id="email" class="required email text"/><span class="errMsg"></span>
       </p>
       <p>
         <label for="extra">*Question:</label>
         <textarea name="onlyText" id="onlyText" class=""></textarea><span class="errMsg"></span>
       </p>

       <button type="submit" id="send">Send Now</button>
       <div id="results"></div>
    </form>

我的jQuery

    <script>
      jQuery(document).ready(function($){           
        $.validator.addMethod("regex",function(value, element, regexp) {
         var check = false;
         var re = new RegExp(regexp);
         return this.optional(element) || re.test(value);
        },
          "No special Characters allowed here. Use only upper and lowercase letters (A through Z; a through z), numbers and punctuation marks (. , ; ? ' ' \" -  ~ ! @ $ % ^ & * (     ) _ + / < > { } )"
        );
        $("#contact").validate({
         rules: {
            onlyText:{
              required: true,
              maxlength: 8000,
              regex: /^[0-9A-Za-z\s`~!@$%^&*()+{}|;'",.<>\/?\\-]+$/
            },
            name:{
              required: false,
              maxlength: 75,
              regex: /^[0-9A-Za-z\s`~!@$%^&*()+{}|;'",.<>\/?\\-]+$/
           }
         } , 
          errorPlacement: function(error, element) {
          error.appendTo( element.next() );  //* THIS IS WHERE I AM HAVING TROUBLE WITH
     });
     });
   </script>

您可以避免麻烦并使用errorElement和errorClass选项让插件为您添加正确的元素：

$("#contact").validate({
    errorElement: 'span',
    errorClass: 'errMsg',
    rules: {
            onlyText:{
              required: true,
              maxlength: 8000,
              regex: /^[0-9A-Za-z\s`~!@$%^&*()+{}|;'",.<>\/?\\-]+$/
            },
            name:{
              required: false,
              maxlength: 75,
              regex: /^[0-9A-Za-z\s`~!@$%^&*()+{}|;'",.<>\/?\\-]+$/
           }
         } 
    });

jQuery Validation插件（link to validate()）为您提供了指定要用于错误消息的标记的选项：

errorElement: "span"

如果不指定此选项，validate()将默认为label。
