各种小问题

Struts2 标签时间处理 name 是从Action里取出来的值

<s:date name="#request.sysEmployee.modifytime" format="yyyy-MM-dd"/>

邮箱验证：

验证邮箱的格式

 <script type="text/javascript">
           function isEmailAddr(elem){
                 var str=elem.value;
                 var re=/^[\w-]+(\.[\w]+)*@([\w-]+\.)+[a-zA-z]{2,7}$/;
                 if(!str.match(re)){
                       alert("这个不是电子邮件");
                       return false;
                     }
                  else{
                       return true;
                      }
               }
    </script>
    <input type="text" name="email" onchange="isEmailAddr(this)" />

3.选择框的处理

<select name="sysEmployee.enable" id="sysEmployee.enable">
<option selected="#request.sysEmployee.enable==0 " value="0">是</option>
<option selected="#request.sysEmployee.enable==1 " value="1">否</option>
</select>
