js动态刷新时间

<script type="text/javascript">
    //取得系统当前时间
    function getTime(){
        var myDate = new Date();
        var date = myDate.toLocaleDateString();
        var hours = myDate.getHours();
        var minutes = myDate.getMinutes();
        var seconds = myDate.getSeconds();
        $("#showDate").html(date+" "+hours+":"+minutes+":"+seconds); //将值赋给div
    }
    window.setInterval("getTime()",1000); //每一秒刷新
</script>
