我有一个带有文章的json提要(每隔几天就会有新的提要)，我需要获取最新的三个.问题是，json不按日期排序，我也不知道如何按日期将其从新到旧排列.我使用js/jQuery.我的json文件看起来像这样:

i have a json feed with articles in it (and new coming every few days) and i need to get latest three out. The problem is, that json is not sorted by date and i don't know, how to rearrange it newest to oldest by date. I use js/jQuery. My json file looks like this:

[ { "author":"some text", "title":"some text", "description":"some text", "image_big":"image link", "image_small":"image link", "date":"2015-06-17", "content":"some text some text some text some text some text", "category":"category", "subcategory":[ "some subcategory" ], "keywords":"keywords,keywords...", "id":"45654", "url":"article link" }, . . (more articles) . ]

推荐答案

You can use Array.sort() function. Something like this:

(function() { var data = [{ "author": "some text", "title": "some text", "description": "some text", "image_big": "image link", "image_small": "image link", "date": "2015-06-17", "content": "some text some text some text some text some text", "category": "category", "subcategory": [ "some subcategory" ], "keywords": "keywords,keywords...", "id": "45654", "url": "article link" }, { "author": "some text 2", "title": "some text 2", "description": "some text 2", "image_big": "image link 2", "image_small": "image link 2", "date": "2015-06-20", "content": "some text some text some text some text some text", "category": "category", "subcategory": [ "some subcategory" ], "keywords": "keywords,keywords...", "id": "45654", "url": "article link" }]; console.log(data.sort(function(a, b) { return b.date > a.date; })); })();
