下面是将秒转换为hh-mm-ss格式的代码:

var measuredTime = new Date(null);
measuredTime.setSeconds(4995); // specify value of SECONDS
var MHSTime = measuredTime.toISOString().substr(11, 8);

在JavaScript中获得从将秒转换为HH-MM-SS格式的替代方法

你也可以使用下面的代码:

int ss = nDur%60;
nDur   = nDur/60;
int mm = nDur%60;
int hh = nDur/60;

这里有一个转换时间的简单函数，可能会有帮助

function formatSeconds(seconds) {
    var date = new Date(1970,0,1);
    date.setSeconds(seconds);
    return date.toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");
}

你也可以用Sugar。

Date.create().reset().set({seconds: 180}).format('{mm}:{ss}');

这个例子返回'03:00'。

再来看看这个老话题——OP表示HH:MM:SS，许多解决方案都很有效，直到你意识到你需要的时间不止24小时。也许你只需要一行代码。给你:

d=(s)=>{f=Math.floor;g=(n)=>('00'+n).slice(-2);return f(s/3600)+':'+g(f(s/60)%60)+':'+g(s%60)}

它返回H+:MM:SS。要使用它，只需使用:

d(91260);     // returns "25:21:00"
d(960);       // returns "0:16:00"

.．.我试图让它使用尽可能少的代码，这是一种很好的一行程序方法。

var time1 = date1.getTime();
var time2 = date2.getTime();
var totalMilisec = time2 - time1;

alert(DateFormat('hh:mm:ss',new Date(totalMilisec)))
