如何将分钟添加到字符串日期

Question

我有一个来自 API 的日期字符串，看起来像这样 10:00 我需要添加一个 1 和半，我试过这个但它不工作

    moment('10:00').add(90, 'minute')

我期待这个输出 11:30

Answer 1

let time = "10:00"

const add=(minutes)=>{
  let [hr, min] = time.split(":")
  minutes += parseInt(hr)*60 + parseInt(min)
  hr = Math.floor(minutes/60)
  min = minutes %60
  
  //console.log(hr%12+":"+ min)
  return (hr%12+":"+ min)
}

console.log(add(90))

Answer 2

查看内联评论：

let input = "10:00";
let inputParts = input.split(":");    // Split the string at the colon

let d = new Date();                   // Create new date
d.setUTCHours(+inputParts[0] + 1);    // Get first part of string and add 1
d.setUTCMinutes(30);                  // Adjust by 1.5 minutes

// Output in the format you want
console.log(d.getUTCHours() + ":" + d.getUTCMinutes());
