我正在嘗試製作一個倒數計時器，它顯示客戶爲了接收同一天發貨而剩餘的剩餘時間量。JavaScript倒數計時器每天遞歸調用
例如，如果他們在15:30之前購買計時器將會在今天（如果是15:00）在30分鐘內發貨。
但是，當它到達15:30時，我希望它在23小時59分鐘內說明訂單，以便明天收到貨物。很明顯，當它到達午夜時，它將轉向今天。或者它可以只顯示日期/日期，所以今天/明天無關緊要。
我知道我需要再次調用函數查看明天的日期，但我不是很方便與JavaScript，所以無法弄清楚。
有人可以幫忙嗎？
// Set the date we're counting down to
var nowDate = new Date();
var countDownDate = new Date(nowDate.getFullYear(), nowDate.getMonth(), nowDate.getDate(), 15, 30, 0, 0);
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now an the count down date
var distance = countDownDate - now;
// Time calculations for hours, minutes and seconds
var days = Math.floor(distance/(1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24))/(1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60))/(1000 * 60));
var seconds = Math.floor((distance % (1000 * 60))/1000);
// Display the result in the element with id="demo"
if (hours >= 1) {
\t document.getElementById("shipping-countdown").innerHTML = "Order within " + hours + "h "
\t + minutes + "m " + seconds + "s " + "to have your order shipped on " // date of shipment;
}
else if (hours < 1 && minutes < 1) {
\t document.getElementById("shipping-countdown").innerHTML = "Order within " + seconds + "s "
+ "to have your order shipped on " // date of shipment;
}
else {
\t document.getElementById("shipping-countdown").innerHTML = "Order within " + minutes + "m "
+ seconds + "s " + "to have your order shipped on " // date of shipment;
}
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
// Start again but looking at tomorrows date
}
// If the count down is finished, write some text
if (nowDate.getDay() == 0 || nowDate.getDay() == 6) {
clearInterval(x);
document.getElementById("shipping-countdown").innerHTML = "Order within " + days + "d "
+ hours + "h "
\t + minutes + "m " + seconds + "s " + "to have your order shipped on " // Start of the week;
}
}, 1000);<!-- Display the countdown timer in an element -->
<p id="shipping-countdown"></p>
邊注：我的屏幕上，在GMT -0400 EST，計數器當前讀取5h17m出貨，這是我的偏移15:30。但是，真正的運輸切斷（_my_時區）？或者它是託運人/倉庫的時區？如果後者，你需要說明這一點。 – msanford
@msanford這是我已經考慮過的事情，但現在我只想讓它運行格林威治標準時間，因爲其他時區將有他們自己的個人實施。 – James
