给网站添加JavaScript动态运行时间

根据西狂部落阁的文章提供的代码修改下样式，将代码放置在底部模板中或者你需要的地方(footer、sidebar 等等)，我这里的模板是 index.php 中。修改好其中自定义的网站建成时间和相关文字，就可以直接运行了。当然你可以修改 sitetime 的 CSS ,让它更有效果。

注意代码中的 “” ‘’ 引号，复制后要确保是英文状态下的，否则会出错。

<p>博客稳定运行<span style="color: orange;" id="sitetime"></span></p>
<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()
var todayDate = today.getDate()
var todayHour = today.getHours()
var todayMinute = today.getMinutes()
var todaySecond = today.getSeconds()
/* 修改下面的t1数值为网站建成时间（年，月，日，时，分，秒）*/
var t1 = Date.UTC(2013,11,9,0,0,0)
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 = diffYears +' 年 '+ diffDays + ' 天 ' + diffHours + ' 小时 ' + diffMinutes + ' 分钟 ' + diffSeconds + ' 秒'
}
siteTime()
</script>
