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.
中的数据是这样的:

"id": 3,
"name": "Sample"

$ http.get(数据/ SampleData.json);

推荐答案
要做到这一点的唯一方法是遍历数组。显然,如果你确信该结果是由ID排序,你可以做一个二进制搜索
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
