如何对ISO 8601持续时间进行排序

问题描述

如何对ISO 8601持续时间进行排序示例：在JavaScript中两次相同时间之间的“ P1DT02H26M”，

我只是尝试过这种方式。

var asc = true
document.getElementById('durationSort').addEventListener('click',function(){
  if(asc){
    modifiedData.data.offers.sort(function(a,b) {
      var c = a.slices[0].duration,d = b.slices[0].duration; 
      return c-d; 
    })
    asc = false
    offers(modifiedData)
    document.getElementById('durationarrow').innerHTML = '<i class="fas fa-hand-point-down" style="color:#01b1ef;"></i>'
    document.getElementById('arrivalarrow').innerHTML = null
    document.getElementById('depaturearrow').innerHTML = null
    document.getElementById('pricearrow').innerHTML = null
  }else{
    var list1 = modifiedData.data.offers
    list1.sort(function(a,b){
      var c = a.slices[0].duration,d = b.slices[0].duration; 
      return c-d; 
    })
    
    modifiedData.data.offers = list1.reverse()
    asc = true
    offers(modifiedData)
    document.getElementById('durationarrow').innerHTML = '<i class="fas fa-hand-point-up" style="color:#01b1ef;"></i>'
    document.getElementById('arrivalarrow').innerHTML = null
    document.getElementById('depaturearrow').innerHTML = null
    document.getElementById('pricearrow').innerHTML = null
  }
});

解决方法

Moment.js包含parse ISO8601 durations的功能。

一旦有了这个，就可以很容易地对持续时间列表进行排序，我们可以简单地从一个持续时间减去另一个持续时间，以毫秒为单位。

let durations = [{minute: 5,day: 1},{ hour: 10 },{ day: 1,hour: 2,minute: 26 },{ second: 3 },{ day: 20 }].map(d => moment.duration(d).toISOString());

function sortDurations(durations) {
    return [...durations].sort( (a,b) => {
        return moment.duration(a) - moment.duration(b);
    })
}

console.log("Unsorted durations:",durations);
console.log("Sorted durations:",sortDurations(durations));
