        <h2>提交的信息</h2>
        <div class="msg">
            <p></p>

    <form id="regist" class="current1" method="post">           
                <h3>注册</h3>
                <label>邮箱<input type="text" name="email" /><span>邮箱为空</span></label>
                <label>名称<input  type="text" name="name" /><span>用户名为空</span></label>
                <label>密码<input type="password" name="pass" /><span>密码为空</span></label>
                <button type="button">注册</button>        
    </form>
</div>

二, css代码

*{padding: 0;margin: 0;}

/* 清除浮动 */
.clearfix:after {content: "";display: table;clear: both;}
html, body { height: 100%; }
body {    font-family:"Microsoft YaHei"; background:#EBEBEB; background:url(../images/stardust.png);       font-weight: 300;  font-size: 15px;  color: #333;overflow: hidden;}
a {text-decoration: none;}

/*home*/
#home{padding-top:100px;}

.tip{background-color: #FFFFFF;width:360px;  margin:auto; position:relative; 
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.44);

}
.tip h2{ font-weight:normal; padding:10px;border-bottom: 1px solid #E7E7E7;color:#C8C8C8;}
.tip div.msg{ padding:10px;color:#C8C8C8; border-bottom: 1px solid #E7E7E7; word-break:break-all; }

}


.current1{
-moz-transform: scale(0);
-webkit-transform: scale(0);
-o-transform: scale(0);
-ms-transform: scale(0);
transform: scale(0);
-moz-transition: all 0.4s ease-in-out;

}



.current{
-moz-transform: scale(1);
-webkit-transform: scale(1);
-o-transform: scale(1);
-ms-transform: scale(1);
transform: scale(1);

}
#regist h3{ font-size:18px; line-height:25px; font-weight:300; letter-spacing:3px; margin-bottom:22px; color:#C8C8C8;}

#regist button:hover,.tip button:hover{ background:#F87982; color:#000;}

三, JS代码

$(function(){
    $("#regist").addClass("current");    
    
    /**
     * 正则检验邮箱
     * email 传入邮箱
     * return true 表示验证通过
     */
    function check_email(email) {
        if (/^[\w\-\.]+@[\w\-]+(\.[a-zA-Z]{2,4}){1,2}$/.test(email)) return true;
    }
    
    
    //input 按键事件
    $("input[name]").keyup(function(e){
          //禁止输入空格  把空格替换掉
          if($(this).attr('name')=="pass"&&e.keyCode==32){
              $(this).val(function(i,v){
                  return $.trim(v);
              });
          }
          if($.trim($(this).val())!=""){
              $(this).nextAll('span').eq(0).css({display:'none'}); 
          }
    });
    
    
    //错误信息
    var succ_arr=[];
    
    //input失去焦点事件
    $("input[name]").focusout(function(e){
        
            var msg="";
             if($.trim($(this).val())==""){
                  if($(this).attr('name')=='name'){
                          succ_arr[0]=false;
                          msg="用户名为空";
                  }else if($(this).attr('name')=='pass'){
                           succ_arr[1]=false;

                  }
                
            }else{
                  if($(this).attr('name')=='name'){
                          succ_arr[0]=true;
                         
                  }else if($(this).attr('name')=='pass'){
                           succ_arr[1]=true;
                           
                  }else if($(this).attr('name')=='email'){
                         succ_arr[2]=true;
                         if(!check_email($.trim($(this).val()))){
                            succ_arr[2]=false;
                            msg="格式不正确";
                        }
                  }    
            }
              var a=$(this).nextAll('span').eq(0);
             a.css({display:'block'}).text(msg);
    });
    
    
    //Ajax用户注册
    $("button[type='button']").click(function(){
         $("input[name]").focusout();  //让所有的input标记失去一次焦点 来设置msg信息
         for (x in succ_arr){if(succ_arr[x]==false) return;}
         $("#regist").removeClass("current");    
         $(".tip").addClass("current");
         var data=$('#regist').serialize(); //序列化表单元素
         $(".tip p").html(data);
        
        
        /**
             有兴趣的可以到这里 自行发送Ajax请求 实现注册功能
        */
         
        
        
    });
    
    $(".tip button,.tip i").click(function(){
