通过JavaScript中的多个属性对对象数组进行排序
假设我们有一个像这样的对象数组-
const arr = [
{ id: 1, score: 1, isCut: false, dnf: false },
{ id: 2, score: 2, isCut: false, dnf: false },
{ id: 3, score: 3, isCut: false, dnf: false },
{ id: 4, score: 4, isCut: false, dnf: false },
{ id: 5, score: 5, isCut: true, dnf: true },
{ id: 6, score: 6, isCut: true, dnf: false },
{ id: 7, score: 7, isCut: true, dnf: false },
{ id: 8, score: 8, isCut: true, dnf: false },
{ id: 9, score: 9, isCut: true, dnf: false },
{ id: 10, score: 0, isCut: false, dnf: false },
{ id: 11, score: -1, isCut: false, dnf: false },
{ id: 12, score: -2, isCut: false, dnf: true },
{ id: 13, score: -3, isCut: false, dnf: false },
{ id: 14, score: -4, isCut: false, dnf: false },
{ id: 15, score: -5, isCut: false, dnf: false },
{ id: 16, score: 10, isCut: true, dnf: false }
];我们需要按照以下条件对上述数组进行排序-
如果dnf为true，
object goes to bottom; all dnf-objects should be sorted by score
如果问题是真的，
object goes to bottom, but above dnfs; all isCut-objects should be sorted by score
休息应按分数排序，如果分数相等，则按ID排序
示例
为此的代码将是-
const arr = [
{ id: 1, score: 1, isCut: false, dnf: false },
{ id: 2, score: 2, isCut: false, dnf: false },
{ id: 3, score: 3, isCut: false, dnf: false },
{ id: 4, score: 4, isCut: false, dnf: false },
{ id: 5, score: 5, isCut: true, dnf: true },
{ id: 6, score: 6, isCut: true, dnf: false },
{ id: 7, score: 7, isCut: true, dnf: false },
{ id: 8, score: 8, isCut: true, dnf: false },
{ id: 9, score: 9, isCut: true, dnf: false },
{ id: 10, score: 0, isCut: false, dnf: false },
{ id: 11, score: -1, isCut: false, dnf: false },
{ id: 12, score: -2, isCut: false, dnf: true },
{ id: 13, score: -3, isCut: false, dnf: false },
{ id: 14, score: -4, isCut: false, dnf: false },
{ id: 15, score: -5, isCut: false, dnf: false },
{ id: 16, score: 10, isCut: true, dnf: false }
];
const sortComplex = (arr = []) => {
arr.sort(function (a, b) {
const order = (dnf, isCut) => {
return [0, 1, 3, 2][dnf * 2 + isCut];
}
return order(a.dnf, a.isCut) - order(b.dnf, b.isCut) || b.score - a.score;
});
};
sortComplex(arr);
console.log(arr);输出结果
控制台中的输出将是-
[
{ id: 4, score: 4, isCut: false, dnf: false },
{ id: 3, score: 3, isCut: false, dnf: false },
{ id: 2, score: 2, isCut: false, dnf: false },
{ id: 1, score: 1, isCut: false, dnf: false },
{ id: 10, score: 0, isCut: false, dnf: false },
{ id: 11, score: -1, isCut: false, dnf: false },
{ id: 13, score: -3, isCut: false, dnf: false },
{ id: 14, score: -4, isCut: false, dnf: false },
{ id: 15, score: -5, isCut: false, dnf: false },
{ id: 16, score: 10, isCut: true, dnf: false },
{ id: 9, score: 9, isCut: true, dnf: false },
{ id: 8, score: 8, isCut: true, dnf: false },
{ id: 7, score: 7, isCut: true, dnf: false },
{ id: 6, score: 6, isCut: true, dnf: false },
{ id: 5, score: 5, isCut: true, dnf: true },
{ id: 12, score: -2, isCut: false, dnf: true }
]
