一句话(不适合几个小时):

 function sectostr(time) {
    return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
 }

说说我的意见:

function convertSecondsToMinutesAndSeconds(seconds){
            var minutes;
            var seconds;
            minutes = Math.floor(seconds/60);
            seconds = seconds%60;

            return [minutes, seconds];
        }

所以这个:

var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);

将有以下输出:

[1,41];

然后你可以像这样打印它:

console.log('TIME : ' +  minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');

//TIME : 1 minutes, 41 seconds

另一个奇妙的解决方案:

function fancyTimeFormat(duration) { // Hours, minutes and seconds const hrs = ~~(duration / 3600); const mins = ~~((duration % 3600) / 60); const secs = ~~duration % 60; // Output like "1:01" or "4:03:59" or "123:03:59" let ret = ""; if (hrs > 0) { ret += "" + hrs + ":" + (mins < 10 ? "0" : ""); } ret += "" + mins + ":" + (secs < 10 ? "0" : ""); ret += "" + secs; return ret; } console.log( fancyTimeFormat(1), fancyTimeFormat(10), fancyTimeFormat(100), fancyTimeFormat(1000), fancyTimeFormat(10000), );

~~是Math的缩写。楼层，请参阅此链接以获取更多信息

秒到h:mm:ss

var hours = Math.floor(time / 3600);
time -= hours * 3600;

var minutes = Math.floor(time / 60);
time -= minutes * 60;

var seconds = parseInt(time % 60, 10);

console.log(hours + ':' + (minutes < 10 ? '0' + minutes : minutes) + ':' + (seconds < 10 ? '0' + seconds : seconds));

strftime.js (strftime github)是最好的时间格式库之一。它非常轻——30KB——而且非常有效。使用它，您可以在一行代码中轻松地将秒转换为时间，主要依赖于本机Date类。

当创建一个新的Date时，每个可选参数的位置如下:

new Date(year, month, day, hours, minutes, seconds, milliseconds);

因此，如果你初始化一个new Date，所有参数都为0，直到秒，你会得到:

var seconds = 150;
var date = new Date(0,0,0,0,0,seconds);
=> Sun Dec 31 1899 00:02:30 GMT-0500 (EST)

可以看到150秒是2分钟和30秒，如创建的日期所示。然后使用strftime格式(“MM:SS”为“%M:%S”)，它将输出您的分钟字符串。

var mm_ss_str = strftime("%M:%S", date);
=> "02:30"

在一行中，它看起来像这样:

var mm_ss_str = strftime('%M:%S', new Date(0,0,0,0,0,seconds));
=> "02:30"

另外，这将允许您根据秒数交换支持HH:MM:SS和MM:SS。例如:

# Less than an Hour (seconds < 3600)
var seconds = 2435;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "40:35"

# More than an Hour (seconds >= 3600)
var seconds = 10050;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "02:47:30"

当然，如果您希望时间字符串或多或少具有语义，您可以简单地将您想要的任何格式传递给strftime。

var format = 'Honey, you said you\'d be read in %S seconds %M minutes ago!';
strftime(format, new Date(0,0,0,0,0,1210));
=> "Honey, you said you'd be read in 10 seconds 20 minutes ago!"

export function TrainingTime(props) {
    const {train_time } = props;
    const hours = Math.floor(train_time/3600);
    const minutes = Math.floor((train_time-hours * 3600) / 60);
    const seconds = Math.floor((train_time%60));

    return `${hours} hrs  ${minutes} min  ${seconds} sec`;
}
