Question

例如:我有101.2914我想获得1:41.291

我想减去数字负 60 的整数部分，但我不能，因为最终时间可能是 2:XX.XXX

Answer 1

ES6:

const string = '101.2914';
let [sec, milisec] = string.split('.');
sec = +sec;
milisec = milisec.slice(0, 3);

let mins = 0;
while(sec >= 60) {
    mins += 1;
    sec -= 60;
}

const result = `${mins}:${sec}.${milisec}`;

console.log(result);

旧版本:

var string = '101.2914';
var array = string.split('.');
var sec = +array[0];
var milisec = array[1].slice(0, 3);

var mins = 0;
while(sec >= 60) {
    mins += 1;
    sec -= 60;
}

var result = mins + ':' + sec + '.' + milisec;

console.log(result);
