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?

function secondsToTime(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);
if(hours >= 12)
{
var m= 'pm' ;
}
else
{
var m='am'
}
if(hours-12 >0)
{
var hrs = hours-12;
}
else if(hours-12 <0)
{
var hrs = hours;
}
var obj = {
"h": hrs,
"m": minutes,
"s": seconds,
"a":m
};
return obj;
}
var d = new Date();
var n = d.getHours();
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))

主题的变奏。处理个位数秒的方式有点不同
seconds2time(0) -> "0s"
seconds2time(59) -> "59s"
seconds2time(60) -> "1:00"
seconds2time(1000) -> "16:40"
seconds2time(4000) -> "1:06:40"
function seconds2time (seconds) {
var hours = Math.floor(seconds / 3600);
var minutes = Math.floor((seconds - (hours * 3600)) / 60);
var seconds = seconds - (hours * 3600) - (minutes * 60);
var time = "";
if (hours != 0) {
time = hours+":";
}
if (minutes != 0 || time !== "") {
minutes = (minutes < 10 && time !== "") ? "0"+minutes : String(minutes);
time += minutes+":";
}
if (time === "") {
time = seconds+"s";
}
else {
time += (seconds < 10) ? "0"+seconds : String(seconds);
}
return time;
}
s2t=function (t){
return parseInt(t/86400)+'d '+(new Date(t%86400*1000)).toUTCString().replace(/.*(\d{2}):(\d{2}):(\d{2}).*/, "$1h $2m $3s");
}
s2t(123456);
结果:
1d 10h 17m 36s
毫秒到持续时间，简单的方法是:
// To have leading zero digits in strings.
function pad(num, size) {
var s = num + "";
while (s.length < size) s = "0" + s;
return s;
}
// ms to time/duration
msToDuration = function(ms){
var seconds = ms / 1000;
var hh = Math.floor(seconds / 3600),
mm = Math.floor(seconds / 60) % 60,
ss = Math.floor(seconds) % 60,
mss = ms % 1000;
return pad(hh,2)+':'+pad(mm,2)+':'+pad(ss,2)+'.'+pad(mss,3);
}
它将327577转换为00:05:27.577。
更新
另一种不同场景的方法:
toHHMMSS = function (n) {
var sep = ':',
n = parseFloat(n),
sss = parseInt((n % 1)*1000),
hh = parseInt(n / 3600);
n %= 3600;
var mm = parseInt(n / 60),
ss = parseInt(n % 60);
return pad(hh,2)+sep+pad(mm,2)+sep+pad(ss,2)+'.'+pad(sss,3);
function pad(num, size) {
var str = num + "";
while (str.length < size) str = "0" + str;
return str;
}
}
toHHMMSS(6315.077) // Return 01:45:15.077
function secToTime(seconds, separator) {
return [
parseInt(seconds / 60 / 60),
parseInt(seconds / 60 % 60),
parseInt(seconds % 60)
].join(separator ? separator : ':')
.replace(/\b(\d)\b/g, "0$1").replace(/^00\:/,'')
}
你现在可以这样使用它:
alert(secToTime("123"));
工作代码片段:
函数secToTime(秒，分隔符){ 返回( parseInt(seconds / 60 / 60)， parseInt(seconds / 60% 60)， parseInt(seconds % 60) ]。加入(分离器?分隔符:':') .replace (/ \ b \ b / g (\ d),“0 1美元”).replace(/ ^ 00 \: /,”) ｝ console.log (secToTime (" 123 "));
function secondsToTime(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);
if(hours >= 12)
{
var m= 'pm' ;
}
else
{
var m='am'
}
if(hours-12 >0)
{
var hrs = hours-12;
}
else if(hours-12 <0)
{
var hrs = hours;
}
var obj = {
"h": hrs,
"m": minutes,
"s": seconds,
"a":m
};
return obj;
}
var d = new Date();
var n = d.getHours();
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))
