希望你一切都好，
我一直在努力寻找一种方法来显示自特定日期以来的年数，月数，周数和天数。我发现的最接近的是下面的内容，但是我可以算出如何显示年份和月份的信息。
任何提示将非常感谢。
谢谢
window.onload = function() {
doTime('jan,01,2017,00:00:01');
}
function doTime(then) {
now = new Date();
then = new Date(then);
difference = (now - then);
days = Math.floor(difference / (60 * 60 * 1000 * 24) * 1);
hours = Math.floor((difference % (60 * 60 * 1000 * 24)) / (60 * 60 * 1000) * 1);
mins = Math.floor(((difference % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) / (60 * 1000) * 1);
secs = Math.floor((((difference % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) % (60 * 1000)) / 1000 * 1);
document.getElementById('timer').firstChild.nodeValue =
+days + ' days ' + hours + ' hours ' + mins + ' minutes ' + secs + ' seconds';
clearTimeout(doTime.to);
doTime.to = setTimeout(function() {
doTime(then);
}, 1000);
}
<div id="timer"> </div>
-感谢上一篇文章的建议，可惜我已经尝试过了，我只能让它处理两个实际日期之间的差额，我现在无法让它自动确定结束日期，因此随着时间的流逝它会自动计数。
-我做了更多的摆弄，并且设法做到这一点，对js来说是新手，你们会说这很接近吗？谢谢
var startDateTime = new Date(2012,5,24,09,43,0,0); // YYYY (M-1) D H m s
(start time and date from DB)
var startStamp = startDateTime.getTime();
var newDate = new Date();
var newStamp = newDate.getTime();
var timer;
function updateClock() {
newDate = new Date();
newStamp = newDate.getTime();
var diff = Math.round((newStamp-startStamp)/1000)
var years = Math.floor(diff/(12*4.3479*7*24*60*60));
diff = diff-(years*12*4.3479*7*24*60*60)
var months = Math.floor(diff/(4.3479*7*24*60*60));
diff = diff-(months*4.3479*7*24*60*60)
var weeks = Math.floor(diff/(7*24*60*60));
diff = diff-(weeks*7*24*60*60)
var days = Math.floor(diff/(24*60*60));
diff = diff-(days*24*60*60);
var hours = Math.floor(diff/(60*60));
diff = diff-(hours*60*60);
var mins = Math.floor(diff/(60));
diff = diff-(mins*60);
var secs = diff;
document.getElementById("time-elapsed").innerHTML = years+" years,
"+months+" months, " +weeks+" weeks, " +days+" days, "+hours+" hours and
"+mins+" minutes,";
}
setInterval(updateClock, 1000);
<div id="time-elapsed"></div>
再次感谢，我只是想知道有没有一种简单的方法可以使像这样的脚本在野生动物园工作？
@lionnn野生动物园有什么问题？
