另一种更优雅的解决方案如下:

/**
 * Convert number secs to display time
 *
 * 65 input becomes 01:05.
 *
 * @param Number inputSeconds Seconds input.
 */
export const toMMSS = inputSeconds => {
    const secs = parseInt( inputSeconds, 10 );
    let minutes = Math.floor( secs / 60 );
    let seconds = secs - minutes * 60;

    if ( 10 > minutes ) {
        minutes = '0' + minutes;
    }
    if ( 10 > seconds ) {
        seconds = '0' + seconds;
    }

    // Return display.
    return minutes + ':' + seconds;
};

要添加前导零，我只需这样做:

const secondstom昆虫填充=时间=> { const minutes = "0" + Math。楼层(时间/ 60); Const seconds = "0" +(时间-分钟* 60); 返回minutes.substr(-2) + ":" + seconds.substr(-2); }; console.log (secondsToMinSecPadded (241));

很好，很短

  function formatSeconds(s: number) {
    let minutes = ~~(s / 60);
    let seconds = ~~(s % 60);
    return minutes + ':' + seconds;
  }

function secondsToMinutes(time){
    return Math.floor(time / 60)+':'+Math.floor(time % 60);
}

您已经编写了足够多的代码来跟踪时间的分钟和秒部分。

你可以把时间因素加进去:

var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);

var mind = hrd % 60;
var minutes = Math.floor(mind / 60);

var secd = mind % 60;
var seconds = Math.ceil(secd);

var moreminutes = minutes + hours * 60

对于那些希望能快速简单地将秒格式化为M:SS的人来说:

function fmtMSS(s){return(s-(s%=60))/60+(9<s?':':':0')+s}

做. . 该函数接受一个数字(首选)或一个字符串(2转换'惩罚'，你可以通过在函数调用的参数s中前置+来减半，如:fmtMSS(+strSeconds))，表示正整数秒s作为参数。

例子:

fmtMSS(    0 );  //   0:00
fmtMSS(   '8');  //   0:08
fmtMSS(    9 );  //   0:09
fmtMSS(  '10');  //   0:10
fmtMSS(   59 );  //   0:59
fmtMSS( +'60');  //   1:00
fmtMSS(   69 );  //   1:09
fmtMSS( 3599 );  //  59:59
fmtMSS('3600');  //  60:00
fmtMSS('3661');  //  61:01
fmtMSS( 7425 );  // 123:45

分解:

function fmtMSS(s){   // accepts seconds as Number or String. Returns m:ss
  return( s -         // take value s and subtract (will try to convert String to Number)
          ( s %= 60 ) // the new value of s, now holding the remainder of s divided by 60 
                      // (will also try to convert String to Number)
        ) / 60 + (    // and divide the resulting Number by 60 
                      // (can never result in a fractional value = no need for rounding)
                      // to which we concatenate a String (converts the Number to String)
                      // who's reference is chosen by the conditional operator:
          9 < s       // if    seconds is larger than 9
          ? ':'       // then  we don't need to prepend a zero
          : ':0'      // else  we do need to prepend a zero
        ) + s ;       // and we add Number s to the string (converting it to String as well)
}

注意:负数范围可以通过在返回表达式前加上(0>s?(s=-s，'-'): ")+来增加(实际上，(0>s?(s=-s，'-'):0)+也可以)。
