js数字时钟

<script type="text/javascript">//获取时间function getTime(){//获取年月日时分秒var myDate = new Date();var y = myDate.getFullYear();    //获取完整的年份(4位,1970-????)var m = check(myDate.getMonth()+1);       //获取当前月份(0-11,0代表1月)var d = check(myDate.getDate());        //获取当前日(1-31)var day = myDate.getDay();         //获取当前星期X(0-6,0代表星期天)var w = "星期" + "日一二三四五六".charAt(day);var h = check(myDate.getHours());       //获取当前小时数(0-23)var i = check(myDate.getMinutes());     //获取当前分钟数(0-59)var s = check(myDate.getSeconds());     //获取当前秒数(0-59)var ms = check(myDate.getMilliseconds());    //获取当前毫秒数(0-999)document.getElementById("date").innerHTML=y+"年"+m+"月"+d+"日"+" "+w;document.getElementById("time").innerHTML=h+":"+i+":"+s+":"+ms;setTimeout(getTime,1); //1毫秒执行一次}//补0函数function check(key){if(key<10)key="0"+key;return key;}getTime();</script>
