js实现网站运行时间统计效果,如上图,废话不多说,直接上代码:
<span id="sitetime"></span><script language=javascript> function siteTime(){ window.setTimeout("siteTime()", 1000); var seconds = 1000; var minutes = seconds * 60; var hours = minutes * 60; var days = hours * 24; var years = days * 365; var today = new Date(); var todayYear = today.getFullYear(); var todayMonth = today.getMonth()+1; var todayDate = today.getDate(); var todayHour = today.getHours(); var todayMinute = today.getMinutes(); var todaySecond = today.getSeconds(); /* Date.UTC() -- 返回date对象距世界标准时间(UTC)1970年1月1日午夜之间的毫秒数(时间戳) year - 作为date对象的年份,为4位年份值 month - 0-11之间的整数,做为date对象的月份 day - 1-31之间的整数,做为date对象的天数 hours - 0(午夜24点)-23之间的整数,做为date对象的小时数 minutes - 0-59之间的整数,做为date对象的分钟数 seconds - 0-59之间的整数,做为date对象的秒数 microseconds - 0-999之间的整数,做为date对象的毫秒数 */ var t1 = Date.UTC(2016,12,01,00,00,00); //北京时间2016-12-1 00:00:00 var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond); var diff = t2-t1; var diffYears = Math.floor(diff/years); var diffDays = Math.floor((diff/days)-diffYears*365); var diffHours = Math.floor((diff-(diffYears*365+diffDays)*days)/hours); var diffMinutes = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours)/minutes); var diffSeconds = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours-diffMinutes*minutes)/seconds); document.getElementById("sitetime").innerHTML=" 已运行"+diffYears+" 年 "+diffDays+" 天 "+diffHours+" 小时 "+diffMinutes+" 分钟 "+diffSeconds+" 秒"; } siteTime();</script>
当然了,这个只是简单的效果实现,如果需要有漂亮的样式,还需要书写好对应的样式代码,这里361源码就不多做说明了。演示效果大家可以参看:
