主要实现日期的显示，获取年月日，时分秒、星期、判断闰年

 

<script language="javascript" >

    $(document).ready(

function(){

        

function show(){

            

var mydate=

new Date();

            

var str = "" + mydate.getFullYear() + "年";

            str += (mydate.getMonth() + 1) + "月";

            str += mydate.getDate() + "日&nbsp;&nbsp;<br/>";

            str += mydate.toLocaleTimeString();

            str += ":" + mydate.toLocaleTimeString();

            str += ":" + mydate.getMilliseconds() + "&nbsp;&nbsp;<br/>星期";

            str += "天一二三四五六".charAt(mydate.getDay()) + "<br/>今年是闰年吗?:";

            str += ((mydate.getFullYear() % 4 == 0 && mydate.getFullYear() % 100 != 0) || (mydate.getFullYear() % 400 == 0)) ? "是" : "不是";          };

        

function flush(){

            $("#btnShow").click(show);

        }

        setInterval(show,1000);

    });  

    

</script>
