lodash orderBy通过嵌套属性 [英] lodash orderBy on nested property

问题描述

我正在使用v4.11.0. 我想基于milliseconds属性对对象进行排序. 这是数组:

I'm using v4.11.0. I would like sort objects based on milliseconds property. Here's the array :

[
    {
        "name": "bug12755.xml",
        "list": "bugs42",
        "start-date": "2015-09-14",
        "age": {
            "text": "7 months",
            "milliseconds": 18381227304
        }
    },
    {
        "name": "bug12922.xml",
        "list": "bugs42",
        "start-date": "2015-08-27",
        "age": {
            "text": "8 months",
            "milliseconds": 19936427304
        }
    },
    {
        "name": "bug13183.xml",
        "list": "bugs50",
        "start-date": "2015-08-27",
        "age": {
            "text": "8 months",
            "milliseconds": 19936427305
        }
    }
]

我缺少有关iteratee函数的一些基本知识.我有这个，但似乎不对数组进行排序.预先感谢！

I'm missing something fundamental about the iteratee function. I have this but does not seem to sort the array. Thanks in advance!

 _.orderBy(list, function(item) {
            return item.age.value;
        }, ['desc']);

推荐答案

似乎您是通过属性value订购的.

It seems that you are ordering by the property value.

u.orderBy(list, function(e) { return e.age.milliseconds}, ['desc']);
