我在我的網站上有這個計時器,我使用下面的腳本來改變日期和時間。如何重置Javascript上的計時器?
我想進行一些編輯,以便每天早上12點自動重置。
另外,我希望腳本檢查客戶端的時間並根據用戶的時間進行重置。
有人可以幫忙嗎?
<script>
// set the date we're counting down to
var target_date = new Date("Nov 23, 2016 0:00:00").getTime();
// variables for time units
var days, hours, minutes, seconds;
// get tag element
var countdown = document.getElementById("countdown");
// update the tag with id "countdown" every 1 second
setInterval(function() {
// find the amount of "seconds" between now and target
var current_date = new Date().getTime();
var seconds_left = (target_date - current_date)/1000;
// do some time calculations
days = parseInt(seconds_left/86400);
seconds_left = seconds_left % 86400;
hours = parseInt(seconds_left/3600);
seconds_left = seconds_left % 3600;
minutes = parseInt(seconds_left/60);
seconds = parseInt(seconds_left % 60);
// format countdown string + set tag value
// countdown.innerHTML = days + "d, " + hours + "h, "
// + minutes + "m, " + seconds + "s";
$('.days').html(days)
$('.hours').html(hours)
$('.minutes').html(minutes)
$('.seconds').html(seconds)
}, 1000);
</script>
