BlueLake主题页脚添加建站时间

为BlueLake主题页脚添加建站时间

---

页脚文件

themes/BlueLake/layout/_partial/footer.jade

添加内容

页脚引用js文件

在合适的位置加上

span
  a(id="sitetime")
  script(language=javascript src=url_for(theme.js) + '/settime.js')

js内容

js存放位置 themes/BlueLake/source/js/settime.js
修改里面的建站时间，已经把年的显示注释掉了，需要可自行修改。

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(2019,12,30,18,00,00); //建站时间
    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=" 本站已运行"+/*diffYears+" 年 "+*/diffDays+" 天 "+diffHours+" 小时 "+diffMinutes+" 分钟 "+diffSeconds+" 秒";
}
siteTime();

注意使用jade格式！！！
缩进使用空格
