如何使用JavaScript将秒转换为HH-MM-SS字符串?
当前回答
试试这个:
function toTimeString(seconds) {
return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}
其他回答
你也可以使用下面的代码:
int ss = nDur%60;
nDur = nDur/60;
int mm = nDur%60;
int hh = nDur/60;
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(':');
};
我遇到了一些人提到的情况,其中秒的数量超过了一天。以下是@Harish Anchu评分最高的答案的改编版本,该答案解释了更长的时间:
function secondsToTime(seconds) {
const arr = new Date(seconds * 1000).toISOString().substr(11, 8).split(':');
const days = Math.floor(seconds / 86400);
arr[0] = parseInt(arr[0], 10) + days * 24;
return arr.join(':');
}
例子:
secondsToTime(101596) // outputs '28:13:16' as opposed to '04:13:16'
已经有很多答案了,但我的要求是:
转换为持续时间(即,应适用于大于24小时的值) 关心的小数秒到给定的十进制精度 如果为零,则截断前面的小时和分钟。
const seconds2duration = ( seconds, decimals=0 ) => { let fraction = ( seconds - Math.floor( seconds ) ).toFixed( decimals ); fraction = decimals === 0 ? '' : fraction.slice( 1 ); const [ hours, mins, secs ] = [ seconds / 3600, seconds % 3600 / 60, seconds % 3600 % 60 ].map( ( x ) => String( Math.floor( x ) ).padStart( 2, '0' ) ); if ( hours === '00' && mins === '00' ) { return secs + fraction; } else if ( hours === '00' ) { return [ mins, secs + fraction ].join( ':' ); } else { return [ hours, mins, secs + fraction ].join( ':' ); } }; console.log(seconds2duration(25*3600 + 0*60 + 41 + 0.333, 0)); // 25:00:41 console.log(seconds2duration(0*3600 + 5*60 + 41 + 0.333, 0)); // 05:41 console.log(seconds2duration(0*3600 + 5*60 + 41 + 0.333, 1)); // 05:41.3 console.log(seconds2duration(0*3600 + 0*60 + 41 + 0.333, 2)); // 41.33
var time1 = date1.getTime();
var time2 = date2.getTime();
var totalMilisec = time2 - time1;
alert(DateFormat('hh:mm:ss',new Date(totalMilisec)))
