我正在及时运行'网络研讨会,每次展示网络研讨会,' 30,'过去45小时和60小时。
我有一个倒数计时器配置为倒计时到下一个四分之一小时,但我也希望文本显示如下:
'下次网络研讨会于上午10:15'
目前,文本始终显示小时时间的顶部。例如上午10:00或下午6:00,并且没有显示15,30或45个间隔。
我的问题是:如何配置文字以显示下次网络研讨会的正确时间,如何配置倒计时以显示倒计时直至下一个小时?
以下是代码:
<script>
$(document).on("ready", function(){
// change to todays date:
//$(".topHour_date").text( "(TODAY) " + moment().format('dddd MMMM Do') );
$(".topHour_date").text("NEXT CLASS TODAY ");
// change next house
$(".topHour_time").text( moment().add(0.1, 'hour').startOf('hour').format('h:mm A'));
$time_now = moment().format("mm");
$time_now_difference = 15 - $time_now;
$time_now_diff_seconds = $time_now_difference * 60;
$.countdown.setDefaults($.countdown.regionalOptions["eng"]);
$(".elCountdownEvergreen").countdown({
until: $time_now_diff_seconds,
padZeroes: true
});
});
</script>

问题是缺少有关所需外部脚本的一些重要详细信息。我猜您使用的是“ moment.js”,但无法识别用于显示倒计时的脚本。
无论如何,您要查找的代码(用于计算下一个开始时间)如下:
var next = new Date(); // now
next.setTime(next.getTime() + 15 * 60 * 1000) // add 15 minutes
next.setMinutes(15 * Math.floor(next.getMinutes() / 15)) // rounding to the start of quarter or hour
next.setSeconds(0) // the period starts in 00 seconds of minute.
// format the output
next = moment(next).format('h:mm A')
// ... and display the next quarter of hour with
$('#some_output_div').text(next)

只需复制并粘贴以下代码
<!-- Display the countdown timer in an element -->
<p id="demo"></p>
<script>
// Set the date we're counting down to
var countDownDate = new Date().getTime() + 15 * 60 * 1000;
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for hours, minutes and seconds
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"
document.getElementById("demo").innerHTML = hours + ":"
+ minutes + ":" + seconds;
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
</script>
