javascript - 在 JavaScript 中从现在开始对时间数组进行排序

问题描述

嗨，我试图从时间数组中创建一个排序，结果应该是当前时间的最近时间（来自数组）

例子 ：

const current_time = new Date() //sample 13:40

时间数组：

const data = ["06:30:00",
            "09:00:00",
            "11:30:00",
            "13:00:00",
            "14:30:00",
            "15:00:00",
            "17:30:00" ,
            "18:00:00"]

调用函数进行排序

const result = createTimeSort(current_time , data)

预期结果

//Sample 1 Time 13:40
["13:00:00","14:30:00","15:00:00","17:30:00","18:00:00","06:30:00","09:00:00","11:30:00"]

// Sample 2 Time 17:50
// ["17:30:00","18:00:00","06:30:00","09:00:00","11:30:00","13:00:00","14:30:00","15:00:00"]

解决方案

如果您想获得想要的结果，您可以对数组进行排序并在想要的时间内获取一个带有偏移量的新数组。

function createTimeSort(time, [...array]) {
    array.sort();
    let index = array.findIndex(s => s > time);
    index -= index && 1;
     
    return index
        ? [...array.slice(index), ...array.slice(0, index)]
        : array;
}

const
  data = ["06:30:00", "09:00:00", "11:30:00", "13:00:00", "14:30:00", "15:00:00", "17:30:00", "18:00:00"];

console.log(...createTimeSort('13:40', data));
// ["13:00:00", "14:30:00", "15:00:00", "17:30:00", "18:00:00", "06:30:00", "09:00:00", "11:30:00"]

console.log(...createTimeSort('17:50', data));
// ["17:30:00", "18:00:00", "06:30:00", "09:00:00", "11:30:00", "13:00:00", "14:30:00", "15:00:00"]

console.log(...createTimeSort('17:29', data));
console.log(...createTimeSort('17:30:00', data));
