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?

下面是它的es6版本:

export const parseTime = (time) => { // send time in seconds
// eslint-disable-next-line 
let hours = parseInt(time / 60 / 60), mins = Math.abs(parseInt(time / 60) - (hours * 60)), seconds = Math.round(time % 60);
return isNaN(hours) || isNaN(mins) || isNaN(seconds) ? `00:00:00` : `${hours > 9 ? Math.max(hours, 0) : '0' + Math.max(hours, 0)}:${mins > 9 ? Math.max(mins, 0) : '0' + Math.max(0, mins)}:${seconds > 9 ? Math.max(0, seconds) : '0' + Math.max(0, seconds)}`;}

            //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

以下是2019年更新的一句话:

//your date
var someDate = new Date("Wed Jun 26 2019 09:38:02 GMT+0100") 

var result = `${String(someDate.getHours()).padStart(2,"0")}:${String(someDate.getMinutes()).padStart(2,"0")}:${String(someDate.getSeconds()).padStart(2,"0")}`

//result will be "09:38:02"

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;
}

我最喜欢Webjins的答案,所以我扩展了它以显示d后缀的日子,使显示有条件,并包括一个s后缀的普通秒:

function sec2str(t){
    var d = Math.floor(t/86400),
        h = ('0'+Math.floor(t/3600) % 24).slice(-2),
        m = ('0'+Math.floor(t/60)%60).slice(-2),
        s = ('0' + t % 60).slice(-2);
    return (d>0?d+'d ':'')+(h>0?h+':':'')+(m>0?m+':':'')+(t>60?s:s+'s');
}

返回"3d 16:32:12"或"16:32:12"或"32:12"或"12s"

这是另一个版本,也处理天数:

function FormatSecondsAsDurationString( seconds )
{
    var s = "";

    var days = Math.floor( ( seconds / 3600 ) / 24 );
    if ( days >= 1 )
    {
        s += days.toString() + " day" + ( ( days == 1 ) ? "" : "s" ) + " + ";
        seconds -= days * 24 * 3600;
    }

    var hours = Math.floor( seconds / 3600 );
    s += GetPaddedIntString( hours.toString(), 2 ) + ":";
    seconds -= hours * 3600;

    var minutes = Math.floor( seconds / 60 );
    s += GetPaddedIntString( minutes.toString(), 2 ) + ":";
    seconds -= minutes * 60;

    s += GetPaddedIntString( Math.floor( seconds ).toString(), 2 );

    return s;
}

function GetPaddedIntString( n, numDigits )
{
    var nPadded = n;
    for ( ; nPadded.length < numDigits ; )
    {
        nPadded = "0" + nPadded;
    }

    return nPadded;
}
