如何按单个整数字段对JSON排序? [英] How to sort JSON by a single integer field?

问题描述

我有以下JSON:

{
    title: 'title',
    ...,
    order: 0
}, {
    ...,
    order: 9
}, {
    ...,
    order: 2
}

... JSON包含许多字段，如何根据 order 字段对它们进行排序?

... the JSON includes many fields, how can I sort them based on the order field?

我一直在寻找内置在nodejs中的东西，但找不到任何可能对这种情况有用的东西.

I was looking for something build into nodejs but I couldn't find anything that might be useful for that case.

推荐答案

首先，您需要有效的JSON，如下所示:

At first, your need valid JSON, like that:

var unsorted = {
    "items": [
        {
            "title": "Book",
            "order": 0
        },
        {
            "title": "Movie",
            "order": 9
        },
        {
            "title": "Cheese",
            "order": 2
        }
    ]
};

之后，您可以轻松地对items进行排序并将其存储在列表中.

Afterwards you can easily sort the items and store them in a list.

var sorted = unsorted.items.sort(function(a, b) {return a.order - b.order});
