如何将十进制小时值转换为hh：mm：ss [英] How to convert decimal hour value to hh:mm:ss

问题描述

如何将十进制小时值（如1.6578）转换为hh：mm：ss in jquery或javascript？

How can I convert a decimal hour value like 1.6578 to hh:mm:ss in jquery or javascript?

我只能设法用hh：mm使用此代码：

I only managed to do it to hh:mm using this code:

var decimaltime= "1.6578";
var hrs = parseInt(Number(decimaltime));
var min = Math.round((Number(decimaltime)-hrs) * 60);
var clocktime = hrs+':'+min;

推荐答案

你可以这样做：

var decimalTimeString = "1.6578";
var decimalTime = parseFloat(decimalTimeString);
decimalTime = decimalTime * 60 * 60;
var hours = Math.floor((decimalTime / (60 * 60)));
decimalTime = decimalTime - (hours * 60 * 60);
var minutes = Math.floor((decimalTime / 60));
decimalTime = decimalTime - (minutes * 60);
var seconds = Math.round(decimalTime);
if(hours < 10)
{
	hours = "0" + hours;
}
if(minutes < 10)
{
	minutes = "0" + minutes;
}
if(seconds < 10)
{
	seconds = "0" + seconds;
}
alert("" + hours + ":" + minutes + ":" + seconds);
