toHHMMSS的非原型版本:

    function toHHMMSS(seconds) {
        var sec_num = parseInt(seconds);
        var hours   = Math.floor(sec_num / 3600);
        var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
        var seconds = sec_num - (hours * 3600) - (minutes * 60);        
        if (hours   < 10) {hours   = "0"+hours;}
        if (minutes < 10) {minutes = "0"+minutes;}
        if (seconds < 10) {seconds = "0"+seconds;}
        var time    = hours+':'+minutes+':'+seconds;
        return time;
    }   

            //secondsToTime();
            var t = wachttijd_sec; // your seconds
            var hour = Math.floor(t/3600);
            if(hour < 10){
                hour = '0'+hour;
            }
            var time = hour+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2);
            //would output: 00:00:00 > +100:00:00

即使超过24小时也能保持倒计时

要获得格式为hh:MM:ss的时间部分，可以使用下面的正则表达式:

(上面有人在同一篇文章中提到了这一点，谢谢。)

var替换= new日期().toTimeString () .replace (/ . * (\ d {2}: \ d {2}: \ d{2})。* / " $ 1 "); console.log(替换)

const secondsToTime = (seconds, locale) => { const date = new date (0); 日期。setHours(0, 0, seconds, 0); 返回date.toLocaleTimeString(地区); ｝ “en”console.log (secondsToTime (3610));

在哪里区域参数(“en”，“de”等)是可选的

新的日期().toString()。分割(" ")[4];

结果15:08:03

在谷歌上搜索的结果是这样的:

function secondsToTime(secs)
{
    secs = Math.round(secs);
    var hours = Math.floor(secs / (60 * 60));

    var divisor_for_minutes = secs % (60 * 60);
    var minutes = Math.floor(divisor_for_minutes / 60);

    var divisor_for_seconds = divisor_for_minutes % 60;
    var seconds = Math.ceil(divisor_for_seconds);

    var obj = {
        "h": hours,
        "m": minutes,
        "s": seconds
    };
    return obj;
}
