如何将秒转换为HH：mm：ss in moment.js [英] How to convert seconds to HH:mm:ss in moment.js

问题描述

如何将秒数转换为 HH：mm：ss ？

目前我正在使用下面的函数

At the moment I am using the function below

render: function (data){
     return new Date(data*1000).toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");;
}

这适用于chrome但在firefox中持续12秒我得到 01:00:12
我想使用moment.js来实现跨浏览器兼容性

This works on chrome but in firefox for 12 seconds I get 01:00:12 I would like to use moment.js for cross browser compatibility

我试过这个但是确实如此不工作

I tried this but does not work

render: function (data){
         return moment(data).format('HH:mm:ss');
}

我做错了什么？

编辑

我设法找到了一个解决方案没有 moment.js，如下所示

I managed to find a solution without moment.js which is as follow

return (new Date(data * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];

仍然很好奇我怎么能在moment.js中做到这一点

Still curious on how I can do it in moment.js

推荐答案

从这篇文章我会试着避免飞跃问题

From this post I would try this to avoid leap issues

moment("2015-01-01").startOf('day')
    .seconds(s)
    .format('H:mm:ss');

我没有运行jsPerf，但我认为这比创建新的日期对象快一百万倍

I did not run jsPerf, but I would think this is faster than creating new date objects a million times

function pad(num) {
    return ("0"+num).slice(-2);
}
function hhmmss(secs) {
  var minutes = Math.floor(secs / 60);
  secs = secs%60;
  var hours = Math.floor(minutes/60)
  minutes = minutes%60;
  return `${pad(hours)}:${pad(minutes)}:${pad(secs)}`;
  // return pad(hours)+":"+pad(minutes)+":"+pad(secs); for old browsers
}

function pad(num) {
    return ("0"+num).slice(-2);
}
function hhmmss(secs) {
  var minutes = Math.floor(secs / 60);
  secs = secs%60;
  var hours = Math.floor(minutes/60)
  minutes = minutes%60;
  return `${pad(hours)}:${pad(minutes)}:${pad(secs)}`;
  // return pad(hours)+":"+pad(minutes)+":"+pad(secs); for old browsers
}

for (var i=60;i<=60*60*5;i++) {
 document.write(hhmmss(i)+'<br/>');
}


/* 
function show(s) {
  var d = new Date();
  var d1 = new Date(d.getTime()+s*1000);
  var  hms = hhmmss(s);
  return (s+"s = "+ hms + " - "+ Math.floor((d1-d)/1000)+"\n"+d.toString().split("GMT")[0]+"\n"+d1.toString().split("GMT")[0]);
}    
*/
