javascript - 如何在 JavaScript 中对对象键中的值进行排序

问题描述

如何仅对键“项目”中的值进行排序？

function solve(input) {
    let heroes = {};

    for (const line of input) {
        let [name, level, items] = line.split(' / ');
        if(!heroes.hasOwnProperty(name)) {
            heroes[name] = {
                level: Number(level),
                items: items
            }
        }
    }

    let inArrEntries = Object.entries(heroes)

    inArrEntries.sort((a, b) => (a[1].level - b[1].level))

    console.log(inArrEntries);
}

输出：

[
  [ 'Hes', { level: 1, items: 'Desolator, Sentinel, Antara' } ],
  [ 'Derek', { level: 12, items: 'BarrelVest, DestructionSword' } ],
  [ 'Isacc', { level: 25, items: 'Apple, GravityGun' } ]
]

预期输出：

[
  [ 'Hes', { level: 1, items: 'Antara, Desolator, Sentinel,' } ],
  [ 'Derek', { level: 12, items: 'BarrelVest, DestructionSword' } ],
  [ 'Isacc', { level: 25, items: 'Apple, GravityGun' } ]
]

解决方案

您可以遍历所有条目，拆分 items，排序", "，然后加入。", "

const inArrEntries = [
  [ 'Hes', { level: 1, items: 'Desolator, Sentinel, Antara' } ],
  [ 'Derek', { level: 12, items: 'BarrelVest, DestructionSword' } ],
  [ 'Isacc', { level: 25, items: 'Apple, GravityGun' } ]
];
for(const entry of inArrEntries){
     entry[1].items = entry[1].items.split(", ").sort().join(", ");
}
document.write(JSON.stringify(inArrEntries));
