统计网站已运行时间--实时计时

统计网站运行时间的js函数

需要修改自己的建站时间

1. <script>
   var now = new Date();
   function createtime(){ var grt= new Date("12/14/2021 00:00:00");//修改建站时间
   now.setTime(now.getTime()+250);
   days = (now - grt ) / 1000 / 60 / 60 / 24;
   dnum = Math.floor(days); hours = (now - grt ) / 1000 / 60 / 60 - (24 * dnum);
   hnum = Math.floor(hours); if(String(hnum).length ==1 ){ hnum = "0" + hnum; } minutes = (now - grt ) / 1000 /60 - (24 * 60 * dnum) - (60 * hnum); mnum = Math.floor(minutes);
   if(String(mnum).length ==1 ){ mnum = "0" + mnum; } seconds = (now - grt ) / 1000 - (24 * 60 * 60 * dnum) - (60 * 60 * hnum) - (60 * mnum); snum = Math.round(seconds);
   if(String(snum).length ==1 ){ snum = "0" + snum; } document.getElementById("timeDate").innerHTML = "本站安全运行 "+dnum+" 天";
   document.getElementById("times").innerHTML = hnum + " 小时 " + mnum + " 分 " + snum + " 秒"; } setInterval("createtime()",250);
   </script>

html代码非常简短

1. <div class="item">
2. <span id="timeDate">载入天数...</span>
3. <br>
4. <span id="times">载入时分秒...</span>
5. </div>
