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?

var d = new Date();

var hms = d.getHours()+':'+d.getMinutes()+':'+d.getSeconds(); // your input string
var a = hms.split(':'); // split it at the colons
// minutes are worth 60 seconds. Hours are worth 60 minutes.
var seconds = (+a[0]) * 60 * 60 + (+a[1]) * 60 + (+a[2]);
console.log(seconds);
console.log(secondsToTime(seconds))

我推荐使用普通的javascript,使用Date对象。(要获得更简短的解决方案,请使用toTimeString,请参阅第二个代码片段。)
var seconds = 9999;
// multiply by 1000 because Date() requires miliseconds
var date = new Date(seconds * 1000);
var hh = date.getUTCHours();
var mm = date.getUTCMinutes();
var ss = date.getSeconds();
// If you were building a timestamp instead of a duration, you would uncomment the following line to get 12-hour (not 24) time
// if (hh > 12) {hh = hh % 12;}
// These lines ensure you have two-digits
if (hh < 10) {hh = "0"+hh;}
if (mm < 10) {mm = "0"+mm;}
if (ss < 10) {ss = "0"+ss;}
// This formats your string to HH:MM:SS
var t = hh+":"+mm+":"+ss;
document.write(t);
(当然,创建的Date对象将有一个与之关联的实际日期,但该数据是无关的,因此出于这些目的,您不必担心它。)
编辑(简短的解决方案):
使用toTimeString函数并对空白进行分割:
var seconds = 9999; // Some arbitrary value
var date = new Date(seconds * 1000); // multiply by 1000 because Date() requires miliseconds
var timeStr = date.toTimeString().split(' ')[0];
toTimeString给出'16:54:58 GMT-0800 (PST)',对第一个空格进行分割给出'16:54:58'。
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;
}
我是这样做的。它似乎工作得相当好,而且非常紧凑。(不过,它使用了很多三元操作符)
function formatTime(seconds) {
var hh = Math.floor(seconds / 3600),
mm = Math.floor(seconds / 60) % 60,
ss = Math.floor(seconds) % 60;
return (hh ? (hh < 10 ? "0" : "") + hh + ":" : "") + ((mm < 10) && hh ? "0" : "") + mm + ":" + (ss < 10 ? "0" : "") + ss
}
...对于格式化字符串…
String.prototype.toHHMMSS = function() {
formatTime(parseInt(this, 10))
};
我会给artem的答案投票,但我是一个新海报。我确实扩展了他的解决方案,虽然不是OP要求的如下
t=(new Date()).toString().split(" ");
timestring = (t[2]+t[1]+' <b>'+t[4]+'</b> '+t[6][1]+t[7][0]+t[8][0]);
得到
0410月16:31:28太平洋时间
这对我很有用……
但如果你从一个时间量开始,我会用两个函数;一个用于格式化和填充,一个用于计算:
function sec2hms(timect){
if(timect=== undefined||timect==0||timect === null){return ''};
//timect is seconds, NOT milliseconds
var se=timect % 60; //the remainder after div by 60
timect = Math.floor(timect/60);
var mi=timect % 60; //the remainder after div by 60
timect = Math.floor(timect/60);
var hr = timect % 24; //the remainder after div by 24
var dy = Math.floor(timect/24);
return padify (se, mi, hr, dy);
}
function padify (se, mi, hr, dy){
hr = hr<10?"0"+hr:hr;
mi = mi<10?"0"+mi:mi;
se = se<10?"0"+se:se;
dy = dy>0?dy+"d ":"";
return dy+hr+":"+mi+":"+se;
}
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');
