如何使用JavaScript将秒转换为HH-MM-SS字符串?
当前回答
下面是一个函数,根据powtac的答案将秒转换为hh-mm-ss格式
斯菲德尔
/**
* Convert seconds to hh-mm-ss format.
* @param {number} totalSeconds - the total seconds to convert to hh- mm-ss
**/
var SecondsTohhmmss = function(totalSeconds) {
var hours = Math.floor(totalSeconds / 3600);
var minutes = Math.floor((totalSeconds - (hours * 3600)) / 60);
var seconds = totalSeconds - (hours * 3600) - (minutes * 60);
// round seconds
seconds = Math.round(seconds * 100) / 100
var result = (hours < 10 ? "0" + hours : hours);
result += "-" + (minutes < 10 ? "0" + minutes : minutes);
result += "-" + (seconds < 10 ? "0" + seconds : seconds);
return result;
}
示例使用
var seconds = SecondsTohhmmss(70);
console.log(seconds);
// logs 00-01-10

试试这个:
function toTimeString(seconds) {
return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}

有很多解决这个问题的选项,显然有很好的选项建议,但我想在这里添加一个更优化的代码
function formatSeconds(sec) {
return [(sec / 3600), ((sec % 3600) / 60), ((sec % 3600) % 60)]
.map(v => v < 10 ? "0" + parseInt(v) : parseInt(v))
.filter((i, j) => i !== "00" || j > 0)
.join(":");
}
如果你不想格式化0和小于10的数字,你可以使用
function formatSeconds(sec) {
return parseInt(sec / 3600) + ':' + parseInt((sec % 3600) / 60) + ':' + parseInt((sec % 3600) % 60);
}
示例代码http://fiddly.org/1c476/1
export const secondsToHHMMSS = (seconds) => {
const HH = `${Math.floor(seconds / 3600)}`.padStart(2, '0');
const MM = `${Math.floor(seconds / 60) % 60}`.padStart(2, '0');
const SS = `${Math.floor(seconds % 60)}`.padStart(2, '0');
return [HH, MM, SS].join(':');
};
简单的函数转换秒为hh:mm:ss格式:
function getHHMMSSFromSeconds(totalSeconds) {
if (!totalSeconds) {
return '00:00:00';
}
const hours = Math.floor(totalSeconds / 3600);
const minutes = Math.floor(totalSeconds % 3600 / 60);
const seconds = totalSeconds % 60;
const hhmmss = padTo2(hours) + ':' + padTo2(minutes) + ':' + padTo2(seconds);
return hhmmss;
}
// function to convert single digit to double digit
function padTo2(value) {
if (!value) {
return '00';
}
return value < 10 ? String(value).padStart(2, '0') : value;
}
