我想转换时间的持续时间，即秒数，以冒号分隔的时间字符串(hh:mm:ss)
我在这里找到了一些有用的答案，但它们都谈到了转换成x小时和x分钟的格式。
那么有一个小片段，这是在jQuery或只是原始JavaScript?
当前回答
function toHHMMSS(seconds) {
var h, m, s, result='';
// HOURs
h = Math.floor(seconds/3600);
seconds -= h*3600;
if(h){
result = h<10 ? '0'+h+':' : h+':';
}
// MINUTEs
m = Math.floor(seconds/60);
seconds -= m*60;
result += m<10 ? '0'+m+':' : m+':';
// SECONDs
s=seconds%60;
result += s<10 ? '0'+s : s;
return result;
}
例子
toHHMMSS(111);
"01:51"
toHHMMSS(4444);
"01:14:04"
toHHMMSS(33);
"00:33"

以下是我的看法:
function formatTime(seconds) {
const h = Math.floor(seconds / 3600);
const m = Math.floor((seconds % 3600) / 60);
const s = Math.round(seconds % 60);
return [
h,
m > 9 ? m : (h ? '0' + m : m || '0'),
s > 9 ? s : '0' + s
].filter(Boolean).join(':');
}
预期结果:
const expect = require('expect');
expect(formatTime(0)).toEqual('0:00');
expect(formatTime(1)).toEqual('0:01');
expect(formatTime(599)).toEqual('9:59');
expect(formatTime(600)).toEqual('10:00');
expect(formatTime(3600)).toEqual('1:00:00');
expect(formatTime(360009)).toEqual('100:00:09');
expect(formatTime(0.2)).toEqual('0:00');
这很简单，
function toTimeString(seconds) {
return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}
最普遍的答案是
function hms(seconds) {
return [3600, 60]
.reduceRight(
(p, b) => r => [Math.floor(r / b)].concat(p(r % b)),
r => [r]
)(seconds)
.map(a => a.toString().padStart(2, '0'))
.join(':');
}
一些示例输出:
> hms(0)
< "00:00:00"
> hms(5)
< "00:00:05"
> hms(60)
< "00:01:00"
> hms(3785)
< "01:03:05"
> hms(37850)
< "10:30:50"
> hms(378500)
< "105:08:20"

我是这么做的
function timeFromSecs(seconds)
{
return(
Math.floor(seconds/86400)+'d :'+
Math.floor(((seconds/86400)%1)*24)+'h : '+
Math.floor(((seconds/3600)%1)*60)+'m : '+
Math.round(((seconds/60)%1)*60)+'s');
}
timeFromSecs(22341938)将返回“258d 14h 5m 38s”
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;
}
