Validform是一款优秀的表单验证插件，layer是一款优秀的弹出窗口插件。下面通过例子看看这二者碰出的火花吧

首先要引入jquery,Validform和layer

<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.9.1/jquery.min.js"></script> 
<script type="text/javascript" src="http://res.layui.com/lay/lib/layer/src/layer.js"></script> 
<script type="text/javascript" src="http://lib.h-ui.net/Validform/5.3.2/Validform.min.js"></script> 

HTML

<form action="post.php" method="post" name="form" class="form form-horizontal" id="form-Validform"> 
  <div class="row cl"> 
   <label class="form-label col-3"><span class="c-red">*</span>用户昵称：</label> 
   <div class="formControls col-8"> 
    <input type="text" class="input-text" value="" placeholder="可使用3-16位中英文字符" id="uname" name="uname" datatype="*2-16" nullmsg="用户昵称不能为空"> 
   </div> 
  </div> 
  <div class="row cl"> 
   <label class="form-label col-3"><span class="c-red">*</span>用户密码：</label> 
   <div class="formControls col-8"> 
    <input type="text" class="input-text" value="" placeholder="5-20位,范围[0-9a-zA-Z_@!.-]" id="pwd" name="pwd" datatype="/w{5,20}/i" nullmsg="用户密码不能为空"> 
   </div> 
  </div> 
   <div class="row cl"> 
     <label class="form-label col-3"><span class="c-red">*</span>Email：</label> 
     <div class="formControls col-8"> 
      <input type="text" class="input-text" value="" placeholder="****@***.***" id="email" name="email" datatype="e" nullmsg="Email不能为空"> 
     </div> 
   </div> 
   <div class="row cl"> 
     <label class="form-label col-3"></label> 
     <div class="formControls col-8"> 
      <a href="javascript:;" id="safecodes" style="color:red"><?php echo $safecode; ?></a> 
     </div> 
   </div> 
  </div> 
  <div class="row cl" style="text-align:center"> 
    <input class="btn btn-primary radius" type="submit" value="  提交  "> 
  </div> 
  </form> 

JS

<script type="text/javascript"> 
$(function(){ 
  $("#form-Validform").Validform({ 
    tiptype:4, 
    ajaxPost:true, 
    callback:function(data){ 
      if(data.status==1){ 
        layer.msg(data.info, {icon: data.status,time: 1000}, function(){ 
          location.reload();//刷新页面 
          });  
      } 
      else{ 
        layer.msg(data.info, {icon: data.status,time: 3000}); 
      } 
    } 
  }); 
  $('#safecodes').click( function () { 
    $('#safecode').val($('#safecodes').text()); 
  }); 
}); 
</script> 

服务端返回

{"info":"u6210u529f","status":1,"url":""} 

本例子流程：点击提交->逐项验证表单->完成验证ajax提交->根据返回信息判断->弹出消息
