当我在 00:53 使用脚本时，倒计时显示最新的 07:00 分钟。当时间到了，倒计时计时器每小时循环 59:59。我怎样才能做到这一点 ？我也需要时间到了，自动刷新页面

我首先尝试了另一种方法，将 php 日期转换为 json 格式 timer.php `<?php include('config.php');

$date=date('Y/m/d H:i:s');

打印 json_encode ($date); ?>`

然后

<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>
<script>
var serverdate;
$.get('localhost/test/timer.php', function(data){
   
   serverDate = data.date; });
setInterval(function(){
const data.date = moment.utc(moment().endOf('hour').diff()).format('HH:mm:ss')
document.getElementById('timer').innerHTML = data.date;
}, 1000);

</script>
</head>
<body>

<div id="timer"></div>



</body>
</html>

我很抱歉缺少我的 javascript =(

我试过moment.js，也许能找到答案。我怎样才能设置这个来连接mysql和ajax？

<script>
setInterval(function(){
const timeString = moment.utc(moment().endOf('hour').diff()).format('HH:mm:ss')
document.getElementById('timer').innerHTML = timeString;
}, 1000);
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>
<div id="timer"></div>
