javascript - Lodash orderBy 对象数组的对象

Question

我有一个数组:

const names = [{name: 'a', equal: 3},
{name: 'b', equal: 2},
{name: 'c', equal: 2},
{name: 'd', equal: 3},
{name: 'a1', equal: 1}]

我正在运行 _.groupBy(names, 'equal') 结果我得到:

{1: [{equal: 1, name: 'a1'}],
 2: [{equal: 2, name: 'b'}, {equal: 2, name: 'c'}],
 3: [{equal: 3, name: 'a'}, {equal: 3, name: 'd'}]}

但是这里按名称排序消失了。如何在此对象中按名称排序？

更新

我想得到:

{3: [{equal: 3, name: 'a'}, {equal: 3, name: 'd'}],
 1: [{equal: 1, name: 'a1'}],
 2: [{equal: 2, name: 'b'}, {equal: 2, name: 'c'}]}

Answer 1

通过使用数组作为结果集，您可以在分组后对它进行排序。

var names = [{ name: 'a', equal: 3 }, { name: 'b', equal: 2 }, { name: 'c', equal: 2 }, { name: 'd', equal: 3 }, { name: 'a1', equal: 1 }],
    equals = {},
    result = [];

names.forEach(function (o) {
    if (!equals[o.equal]) {
        equals[o.equal] = [];
        result.push(equals[o.equal]);
    }
    equals[o.equal].push(o);
});

result.sort(function (a, b) {
    return a[0].name.localeCompare(b[0].name);
});

console.log(result);
