JavaScript根据豪秒数得到时分秒毫秒

Question

求一个JavaScript方法，根据豪秒数得到时分秒毫秒： 如输入 ：1111 输出为：0:0:1 111

Answer 1

var d=new Date(1111);
console.log(d.getUTCHours()+":"+d.getUTCMinutes()+":"+d.getUTCSeconds()+" "+d.getUTCMilliseconds());

Answer 2

代码如下：

var totalMs = 1111;
var ms = totalMs % 1000;
var seconds = (totalMs-ms)/1000;
var minutes =(totalMs-ms-seconds*1000) % 60
var hours = (totalMs-ms-seconds*1000-minutes*60*1000) % 60
var dtStr = hours + ":" + minutes + ":" + seconds + " " + ms;
console.log(dtStr);
