How to convert seconds to minutes and hours in javascript
提问by ALSD Minecraft
I have a count of seconds stored in variable seconds. I want to convert for example 1439 seconds to 23 minutes and 59 seconds. And if the time is greater than 1 hour (for example 9432 seconds), to 2 hours, 37 minutes and 12 seconds.
我有一个存储在变量中的秒数seconds。我想将例如 1439 秒转换为 23 分 59 秒。而如果时间大于 1 小时（例如 9432 秒），则为 2 小时 37 分 12 秒。
How can I achieve this?
我怎样才能做到这一点？
I'm thinking of:
我在想：
var sec, min, hour;
if(seconds<3600){
var a = Math.floor(seconds/60); //minutes
var b = seconds%60; //seconds
if (b!=1){
sec = "seconds";
}else{
sec = "second";
}
if(a!=1){
min = "minutes";
}else{
min = "minute";
}
$('span').text("You have played "+a+" "+min+" and "+b+" "+sec+".");
}else{
var a = Math.floor(seconds/3600); //hours
var x = seconds%3600;
var b = Math.floor(x/60); //minutes
var c = seconds%60; //seconds
if (c!=1){
sec = "seconds";
}else{
sec = "second";
}
if(b!=1){
min = "minutes";
}else{
min = "minute";
}
if(c!=1){
hour = "hours";
}else{
hour = "hour";
}
$('span').text("You have played "+a+" "+hour+", "+b+" "+min+" and "+c+" "+sec+".");
}
But that's a lot of code, and it has to be calculated each second. How can I shrink this up?
但那是很多代码，而且必须每秒计算一次。我怎样才能缩小这个？

I think you would find this solutionvery helpful.
我想你会发现这个解决方案非常有帮助。
You modify the display format to fit your needs with something like this -
您可以使用以下内容修改显示格式以满足您的需求 -
function secondsToHms(d) {
d = Number(d);
var h = Math.floor(d / 3600);
var m = Math.floor(d % 3600 / 60);
var s = Math.floor(d % 3600 % 60);
var hDisplay = h > 0 ? h + (h == 1 ? " hour, " : " hours, ") : "";
var mDisplay = m > 0 ? m + (m == 1 ? " minute, " : " minutes, ") : "";
var sDisplay = s > 0 ? s + (s == 1 ? " second" : " seconds") : "";
return hDisplay + mDisplay + sDisplay;
}

You can try this, i have used this successfully in the past You should be able to add the minutes and seconds on easily
你可以试试这个，我过去成功地使用过你应该能够轻松添加分钟和秒
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);
var obj = {
"h": hours,
"m": minutes,
"s": seconds
};
return obj;
}
You can change the object to
您可以将对象更改为
var obj = {
"h": hours + " hours",
"m": minutes + " minutes",
"s": seconds + " seconds"
};

A low fat way to do this is:
一个低脂肪的方法是：
function seconds_to_days_hours_mins_secs_str(seconds)
{ // day, h, m and s
var days = Math.floor(seconds / (24*60*60));
seconds -= days * (24*60*60);
var hours = Math.floor(seconds / (60*60));
seconds -= hours * (60*60);
var minutes = Math.floor(seconds / (60));
seconds -= minutes * (60);
return ((0<days)?(days+" day, "):"")+hours+"h, "+minutes+"m and "+seconds+"s";
}
Thus
因此
> seconds_to_days_hours_mins_secs_str(9432+60*60*24)
'1 days, 2h, 37m and 12s'
This is easy to understand and extend as needed.
这很容易理解并根据需要进行扩展。

I'm probably a bit late but you can achieve this kind of things using
我可能有点晚了，但你可以使用
myVar = moment(myVar).format('HH:mm');
myVar = moment(myVar).format('HH:mm');
moment provides A LOT of format for hours / dates etc.
moment 为小时/日期等提供了很多格式。

I found Wilson Lee's and Brian's code super useful! Here is how I adapted their code:
我发现 Wilson Lee 和 Brian 的代码非常有用！这是我如何调整他们的代码：
function formatTime(serverTimeinSeconds, elementId)
{ /* This converts seconds into days, hours, minutes and seconds timestring.
Requires JQuery if elementId argument is provided */
seconds = Math.floor(Number(serverTimeinSeconds));
days = Math.floor(seconds / (24*60*60));
seconds -= Math.floor(days * (24*60*60));
hours = Math.floor(seconds / (60*60));
seconds -= Math.floor(hours * (60*60));
minutes = Math.floor(seconds / (60));
seconds -= Math.floor(minutes * (60));
dDisplay = days > 0 ? days + (days == 1 ? ' day, ' : ' days, ') : '';
hDisplay = hours > 0 ? hours + (hours == 1 ? ' hour, ' : ' hours, ') : '';
mDisplay = minutes > 0 ? minutes + (minutes == 1 ? ' minute, ' : ' minutes, ') : '';
sDisplay = seconds > 0 ? seconds + (seconds == 1 ? ' second' : ' seconds') : '';
if (elementId != null) {
if (serverTimeinSeconds < 60) {
$(elementId).css('font-size', '15px');
$(elementId).html(sDisplay);
}
if (serverTimeinSeconds >= 60 && serverTimeinSeconds < 3600) {
$(elementId).css('font-size', '15px');
$(elementId).html(mDisplay + sDisplay);
}
if (serverTimeinSeconds >= 3600 && serverTimeinSeconds < 86400) {
$(elementId).css('font-size', '12px');
$(elementId).html(hDisplay + mDisplay + sDisplay);
}
if (serverTimeinSeconds >= 86400 && serverTimeinSeconds !== Infinity) {
$(elementId).css('font-size', '8px');
$(elementId).html(dDisplay + hDisplay + mDisplay + sDisplay);
}
}
return dDisplay + hDisplay + mDisplay + sDisplay;
}

Try this, Convert SEC to H:M:S.
试试这个，将 SEC 转换为 H:M:S。
function convertTime(sec) {
var hours = Math.floor(sec/3600);
(hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
var min = Math.floor(sec/60);
(min >= 1) ? sec = sec - (min*60) : min = '00';
(sec < 1) ? sec='00' : void 0;
(min.toString().length == 1) ? min = '0'+min : void 0;
(sec.toString().length == 1) ? sec = '0'+sec : void 0;
return hours+':'+min+':'+sec;
}

@pkerckhove has already mentioned momentas a great library to work with dates and times, and you can also use momentto directly format the seconds into OP's desired format, i.e.:
@pkerckhove 已经提到moment了一个很棒的库来处理日期和时间，您还可以使用moment直接将秒格式化为 OP 所需的格式，即：
import moment from 'moment'
const myVar = 1439
console.log(
moment.unix(myVar).utc().format('H [hours,] m [minutes and] s [seconds]')
)
Will result in: 0 hours, 23 minutes and 59 secondsand,
将导致：0 hours, 23 minutes and 59 seconds并且，
import moment from 'moment'
const myVar = 9432
console.log(
moment.unix(myVar).utc().format('H [hours,] m [minutes and] s [seconds]')
)
Will result in: 2 hours, 37 minutes and 12 seconds
会导致： 2 hours, 37 minutes and 12 seconds

Convert to H:M
转换为 H:M
Number(moment.duration(Number(37320), 'seconds').hours()+'.'+moment.duration(Number(37320),'seconds').minutes())
