lodash多列sortBy降序 [英] lodash multi-column sortBy descending

问题描述

基于几个属性对一组对象进行排序有一个很好的方法：

There's a nifty method to sort an array of objects based on several properties:

var data = _.sortBy(array_of_objects, ['type', 'name']);

但这仅适用于升序排序。是否有一些方便的方法来定义每列的方向？例如

However that is only for ascending sorting. Is there some handy way of defining direction per column? E.g.

var data = _.sortBy(array_of_objects, [{'type': 'asc'}, {'name': 'desc'}]);

推荐答案

从 lodash 3.5开始。 0 您可以使用 sortByOrder （更名为 orderBy in v4.3.0）：

As of lodash 3.5.0 you can use sortByOrder (renamed orderBy in v4.3.0):

var data = _.sortByOrder(array_of_objects, ['type','name'], [true, false]);

由于版本3.10.0 ，您甚至可以使用标准语义进行排序（ asc，desc）：

Since version 3.10.0 you can even use standard semantics for ordering (asc, desc):

var data = _.sortByOrder(array_of_objects, ['type','name'], ['asc', 'desc']);

在lodash的版本4 中，此方法已重命名为 orderBy ：

In version 4 of lodash this method has been renamed orderBy:

var data = _.orderBy(array_of_objects, ['type','name'], ['asc', 'desc']);
