javascript - moment.js 获取 hh :mm:ss from a decimal nr

Question

从值 126.55(126 分 55 秒)我怎样才能得到像 02:06:55 这样的输出

var d = moment.duration(126.55,'minutes');
var hours = Math.floor(d.asHours());
var mins = Math.floor(d.asMinutes()) - hours * 60;
var secs = Math.floor(d.asSeconds()) - mins * 60;
console.log(hours + ":" + mins + ":" + secs);

我的输出是 2:6:7233

所需输出02:06:55

Answer 1

我建议使用 moment-duration-format 插件，但是，首先，秒数必须从秒转换为十进制(即:55 秒是百分之 91 秒):

window.onload = function() {
  var min = 6.55;
  min =  parseInt(min)+ (min * 100 % 100) / 60;
  var result = moment.duration(min ,'minutes').format("HH:mm:ss", {trim: false});
  document.getElementById('log').textContent = result;
}
