JS实现 动态时间显示

效果图：

 

页面：<div id="time"></div>

 

下面是js部分：

<script type="text/javascript">
 function time() {
            var vWeek, vWeek_s, vDay;
            vWeek = ["星期天", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六"];
            var date = new Date();
            year = date.getFullYear();
            month = date.getMonth() + 1;
            day = date.getDate();
            hours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
            minutes = date.getMinutes()< 10 ? "0" + date.getMinutes() : date.getMinutes();
            seconds = date.getSeconds()< 10 ? "0" + date.getSeconds() : date.getSeconds();
            vWeek_s = date.getDay();

            document.getElementById("time").innerHTML = "\t" + year + "年" + month + "月" + day + "日" + "\t" + hours + ":" + minutes + ":" + seconds + "\t" + vWeek[vWeek_s];

        };

</script>
