Question

我有这个数组，我想知道我是否可以单独使用属性comments.count和likes.count对其进行排序。

例如，我可以使用likes.count参数或comments.count参数调用函数。

{
    "attribution": null,
    "tags": [

    ],
    "type": "",
    "location": null,
    "comments": {
        "count": 2,
        "data": [
            {
                "created_time": "1385670850",
                "text": "Holy shit",
                "from": {
                    "username": "someone",
                    "profile_picture": "http://url.com/profiles/profile_191120775_75sq_1365830292.jpg",
                    "id": "191120775"
                },
                "id": "599372997379438683"
            },

Answer 1

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

json_array.sort(function(a, b) {
    if(a.comments.count < b.comments.count) {
        return -1;
    }
    if(a.comments.count > b.comments.count) {
        return 1;
    }
    return 0;
});

您也可以修改likes.count

Answer 2

Underscore.js为处理数组和对象提供了很好的实用工具。对于您的情况，您可以使用_.sortBy（...）有关详细信息，请参阅http://underscorejs.org/#sortBy。对于简单的对象属性，只需指定对象属性名称als last参数。

按属性对嵌套数组进行排序
