使用Jquery动态显示年月日星期时间的代码段

<script src="/js/jquery-1.8.3.min.js" type="text/javascript"></script>

<div class="date">  </div>

function getDate() {  
            var today = new Date();  
            var date = today.getFullYear() + "年" + twoDigits(today.getMonth() + 1) + "月" + twoDigits(today.getDate()) + "日 ";  
            var week = " 星期" + "日一二三四五六 ".charAt(today.getDay());  
            var time = twoDigits(today.getHours()) + ":" + twoDigits(today.getMinutes()) + ":" + twoDigits(today.getSeconds());  
            $(".date").html(date + week + time);  
        }  
        function twoDigits(val) {  
            if (val < 10) return "0" + val; return val;  
        }  
        $(function () {  
            setInterval(getDate, 1000);  
        });
