我想转换时间的持续时间,即秒数,以冒号分隔的时间字符串(hh:mm:ss)
我在这里找到了一些有用的答案,但它们都谈到了转换成x小时和x分钟的格式。
那么有一个小片段,这是在jQuery或只是原始JavaScript?

toHHMMSS的非原型版本:
function toHHMMSS(seconds) {
var sec_num = parseInt(seconds);
var hours = Math.floor(sec_num / 3600);
var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
var seconds = sec_num - (hours * 3600) - (minutes * 60);
if (hours < 10) {hours = "0"+hours;}
if (minutes < 10) {minutes = "0"+minutes;}
if (seconds < 10) {seconds = "0"+seconds;}
var time = hours+':'+minutes+':'+seconds;
return time;
}
其他回答
//secondsToTime();
var t = wachttijd_sec; // your seconds
var hour = Math.floor(t/3600);
if(hour < 10){
hour = '0'+hour;
}
var time = hour+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2);
//would output: 00:00:00 > +100:00:00
即使超过24小时也能保持倒计时
在谷歌上搜索的结果是这样的:
function secondsToTime(secs)
{
secs = Math.round(secs);
var hours = Math.floor(secs / (60 * 60));
var divisor_for_minutes = secs % (60 * 60);
var minutes = Math.floor(divisor_for_minutes / 60);
var divisor_for_seconds = divisor_for_minutes % 60;
var seconds = Math.ceil(divisor_for_seconds);
var obj = {
"h": hours,
"m": minutes,
"s": seconds
};
return obj;
}
如果你知道你有多少秒,这就可以了。它还使用本机Date()对象。
function formattime(numberofseconds){
var zero = '0', hours, minutes, seconds, time;
time = new Date(0, 0, 0, 0, 0, numberofseconds, 0);
hh = time.getHours();
mm = time.getMinutes();
ss = time.getSeconds()
// Pad zero values to 00
hh = (zero+hh).slice(-2);
mm = (zero+mm).slice(-2);
ss = (zero+ss).slice(-2);
time = hh + ':' + mm + ':' + ss;
return time;
}
下面是它的es6版本:
export const parseTime = (time) => { // send time in seconds
// eslint-disable-next-line
let hours = parseInt(time / 60 / 60), mins = Math.abs(parseInt(time / 60) - (hours * 60)), seconds = Math.round(time % 60);
return isNaN(hours) || isNaN(mins) || isNaN(seconds) ? `00:00:00` : `${hours > 9 ? Math.max(hours, 0) : '0' + Math.max(hours, 0)}:${mins > 9 ? Math.max(mins, 0) : '0' + Math.max(0, mins)}:${seconds > 9 ? Math.max(0, seconds) : '0' + Math.max(0, seconds)}`;}
我不喜欢在JavaScript中为标准数据类型添加属性,所以我建议这样做:
/**
* Format a duration in seconds to a human readable format using the notion
* "h+:mm:ss", e.g. "4:40:78". Negative durations are preceeded by "-".
*
* @param t Duration in seconds
* @return The formatted duration string
*/
var readableDuration = (function() {
// Each unit is an object with a suffix s and divisor d
var units = [
{s: '', d: 1}, // Seconds
{s: ':', d: 60}, // Minutes
{s: ':', d: 60}, // Hours
];
// Closure function
return function(t) {
t = parseInt(t); // In order to use modulus
var trunc, n = Math.abs(t), i, out = []; // out: list of strings to concat
for (i = 0; i < units.length; i++) {
n = Math.floor(n / units[i].d); // Total number of this unit
// Truncate e.g. 26h to 2h using modulus with next unit divisor
if (i+1 < units.length) // Tweak substr with two digits
trunc = ('00'+ n % units[i+1].d).substr(-2, 2); // …if not final unit
else
trunc = n;
out.unshift(''+ trunc + units[i].s); // Output
}
(t < 0) ? out.unshift('-') : null; // Handle negative durations
return out.join('');
};
})();
用法:
var str = readableDuration(3808); // "1:03:28"
我还创建了一个更通用的版本。主要的区别是它接受毫秒(这是JS中的标准时间单位),而输出格式使用空格。
