按属性值按特定顺序对数组对象进行排序

本文介绍了按属性值按特定顺序对数组对象进行排序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个对象数组，我想使用每个对象的属性值与相应值的有序列表进行比较.

I have an array of objects that I'd like to sort using each object's property value compared against an ordered list of corresponding values.

比方说，我有这个字符串数组；食物组:

Let's say I have this array of strings; food groups:

[ 'protein', 'dairy', 'fruit', 'vegetable' ]

我还有一系列对象，食物，每个对象都属于属性group属于以前的食物组之一:

And I also have an array of objects, food items, each belonging to one of the former food groups by the property group:

[ { group: 'vegetable', name: 'broccoli' }, { group: 'protein', name: 'beef' }, { group: 'fruit', name: 'apple' }, { group: 'vegetable', name: 'peas' }, { group: 'dairy', name: 'cheese' }, { group: 'protein', name: 'tofu' }, { group: 'vegetable', name: 'bell pepper' }, { group: 'dairy', name: 'milk' }, { group: 'fruit', name: 'grapes' }, { group: 'protein', name: 'chicken' }, ]

给出第一个数组中食物组的顺序，如何使用食物的对象group属性对食物进行排序，从而得出结果:

Given the order of the food groups in the first array, how can I sort the food items using their object group properties, to result in this:

[ { group: 'protein', name: 'beef' }, { group: 'protein', name: 'tofu' }, { group: 'protein', name: 'chicken' }, { group: 'dairy', name: 'cheese' }, { group: 'dairy', name: 'milk' }, { group: 'fruit', name: 'apple' }, { group: 'fruit', name: 'grapes' }, { group: 'vegetable', name: 'broccoli' }, { group: 'vegetable', name: 'peas' }, { group: 'vegetable', name: 'bell pepper' }, ]

虽然我使用Javascript进行编码，但是我确信这在几种语言中或多或少都是相同的.

While I'm doing this in Javascript, I'm sure this would be more or less the same across a few languages.

任何帮助将不胜感激！

推荐答案

您可以使用forEach& filter数组方法.遍历food groups&对于每个元素，请从group中过滤出匹配的元素，&存储在新数组中

You can use forEach & filter array method. Iterate over the food groups & for each element filter out the matched element from the group, & store in a new array

var order = ['protein', 'dairy', 'fruit', 'vegetable' ] var orgArry = [{ group: 'vegetable', name: 'broccoli' }, { group: 'protein', name: 'beef' }, { group: 'fruit', name: 'apple' }, { group: 'vegetable', name: 'peas' }, { group: 'dairy', name: 'cheese' }, { group: 'protein', name: 'tofu' }, { group: 'vegetable', name: 'bell pepper' }, { group: 'dairy', name: 'milk' }, { group: 'fruit', name: 'grapes' }, { group: 'protein', name: 'chicken' }, ]; var newArray = []; order.forEach(function(item) { return orgArry.filter(function(groupName) { if (groupName.group === item) { newArray.push(groupName) } }) }); console.log(newArray)
