我需要一些帮助来编写一个脚本，从 UNIX 时间戳开始倒计时天、小时、分钟和秒。
时间戳是用php创建的
<? php echo hours ();?>
我希望脚本能够使用 JavaScript 实时倒计时。
示例 2 天，3:15:39
希望有人能帮助我一点:)
首先你会遇到一些 PHP 错误。应该是例如
<?php echo time(); ?>
我在 JavaScript 中使用时间戳以便于展示示例。

// the difference timestamp
var timestamp = (Date.now() + 1000 * 60 * 60 * 24 * 3) - Date.now();
timestamp /= 1000; // from ms to seconds
function component(x, v) {
return Math.floor(x / v);
}
var $div = $('div');
setInterval(function() { // execute code each second
timestamp--; // decrement timestamp with one second each second
var days = component(timestamp, 24 * 60 * 60), // calculate days from timestamp
hours = component(timestamp, 60 * 60) % 24, // hours
minutes = component(timestamp, 60) % 60, // minutes
seconds = component(timestamp, 1) % 60; // seconds
$div.html(days + " days, " + hours + ":" + minutes + ":" + seconds); // display
}, 1000); // interval each second = 1000 ms
我刚刚重构了上面的代码
var limitDays = 1000 * 60 * 60 * 24 //"24 hours"
var days = 365
var expired = false
var currentTime = new Date()
console.log("set var [ now ] with this: ", currentTime.valueOf())
console.log("set var [ validity ] with this: ", getTime())
function getTime() {
return days * limitDays
}
function component(x, v) {
return Math.floor(x / v);
}
function getTimer(timestamp) {
var interval = setInterval(function() {
timestamp -= 1000
var days = component(timestamp / 1000, 24 * 60 * 60),
hours = component(timestamp / 1000, 60 * 60) % 24,
minutes = component(timestamp / 1000, 60) % 60,
seconds = component(timestamp / 1000, 1) % 60;
document.getElementById('countdown').innerHTML = (days + " days " + hours + " hours " + minutes + " minutes " + seconds + " seconds")
if (timestamp < 0) {
console.log("expired")
clearInterval(interval)
getTimer(getTime())
}
}, 1000)
}
var validity = 31536000000
var now = 1711578707493
var converter = (validity - (currentTime.valueOf() - now))
