「 【WEB】给你的网站增加运行时间代码 」

AI摘要：提供三种HTML代码，用于在网站底部显示网站运行时间，包括天数、小时、分钟和秒。

演示

代码如下[提供三种]

代码一

    <center>
今天是:<span><script language=Javascript type=text/Javascript> 
var day=""; 
var month=""; 
var ampm=""; 
var ampmhour=""; 
var myweekday=""; 
var year=""; 
mydate=new Date(); 
myweekday=mydate.getDay(); 
mymonth=mydate.getMonth()+1; 
myday= mydate.getDate(); 
myyear= mydate.getYear(); 
year=(myyear > 200) ? myyear : 1900 + myyear; 
if(myweekday == 0) 
weekday=" 星期日 "; 
else if(myweekday == 1) 
weekday=" 星期一 "; 
else if(myweekday == 2) 
weekday=" 星期二 "; 
else if(myweekday == 3) 
weekday=" 星期三 "; 
else if(myweekday == 4) 
weekday=" 星期四 "; 
else if(myweekday == 5) 
weekday=" 星期五 "; 
else if(myweekday == 6) 
weekday=" 星期六 "; 
document.write(year+"年"+mymonth+"月"+myday+"日 "+weekday); 
</script>
</div>
<center><b><FONT COLOR="#008B00">【本站已经可爱滴运行】</FONT></b> 
<span id="span_dt_dt"></span> 
<SCRIPT language=javascript> 
<!-- 
//document.write(""); 
function show_date_time(){ 
window.setTimeout("show_date_time()", 1000);

代码二

    <span id="website_runtime"></span>
<script type="text/javascript">

    // 定时器
    window.setTimeout("show_runtime()", 1000);
    // 开始时间
    let start = new Date("2019/02/08 00:00:00");
    // 当前时间
    let now = new Date();
    // 经过时长
    let duration = now.getTime() - start.getTime();
    // 一天的毫秒数
    let msPerDay = 24 * 60 * 60 * 1000;
    // 天
    let _day = duration / msPerDay;
    let day = Math.floor(_day);
    // 小时
    let _hour = (_day - day) * 24;
    let hour = Math.floor(_hour);
    // 分钟
    let _minute = (_hour - hour) * 60;
    let minute = Math.floor(_minute);
    // 秒
    let _second = (_minute - minute) * 60;
    let second = Math.floor(_second);
    // 更新span标签内容
    website_runtime.innerHTML="本站已运行：" + day + "天" + hour + "小时" + minute + "分" + second + "秒";
}
show_runtime();
</script>
