从AngularJS中的对象数组中通过id获取特定对象 [英] Get specific object by id from array of objects in AngularJS

问题描述

我有一个JSON文件，其中包含我想在AngularJS网站上访问的一些数据。现在我想要的是从数组中只获取一个对象。所以我想要例如ID为1的项目。

I have a JSON file containing some data I d like to access on my AngularJS website. Now what I want is to get only one object from the array. So I d like for example Item with id 1.

数据如下所示：

{ "results": [
    {
        "id": 1,
        "name": "Test"
    },
    {
        "id": 2,
        "name": "Beispiel"
    },
    {
        "id": 3,
        "name": "Sample"
    }
] }

我想加载数据AngularJS $ http功能如下：

I d like to load the data with AngularJS $http functionality like this:

$ http.get（data / SampleData.json）;

这是有效的。但是我现在如何从我从 $ http.get 获得的数组中获取特定数据对象（通过id）？

which is working. But how can I now get a specific data object (by id) from the array I get from $http.get ?

预先感谢您的帮助。

迎接

推荐答案

执行此操作的唯一方法是迭代数组。显然，如果您确定结果是按ID排序的，那么您可以执行二进制搜索

The only way to do this is to iterate over the array. Obviously if you are sure that the results are ordered by id you can do a binary search
