自己按照它的文档介绍很快写了一个简单的例子，

<script type="text/javascript" src="http://validform.rjboy.cn/wp-content/themes/validform/js/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="http://validform.rjboy.cn/Validform/v5.1/Validform_v5.1_min.js"></script>


<script>
 $(function(){
 // $(".registForm").Validform();  //就这一行代码！;

  $(".registForm").Validform({tiptype:2});

  });


 </script>



 <form   class="registForm" action="regist.action" method="post" enctype="multipart/form-data">
  <table border="0px" align="center" height="480px" style="color:#666666">
  <tr><td colspan="3" align="center" style="font-size:16px;color:#F07F00">请输入注册信息</td></tr>

   <tr>
   <td align="left">注册邮箱：</td>
   <td><input class="inputxt"  type="text" id="account" name="account"  datatype="e"
     nullmsg="请输入注册邮箱！"  errormsg="不是合法的邮箱！"   /></td>
   <td><div id="accountValidate" class="Validform_checktip"></div></td></tr>

   <tr>
