无需循环获取JSONArray中的索引位置

Question

I have the following JSONObject

{"results":2,"object":[{"id":10,"rank":12},{"id":21,"rank":22}.........{"id":n,"rank":n}]}

Now if I have an id: 21, how do I get the position of that object?

Is there any direct way to get the position of that id?

Like 21 is in 2nd position in that array.So the index position is 1. Is there any direct way without looping the JSONArray to improve the performance?

Answer 1

One thing you can do is to re-structure your json like

{"results":2,"object":{10:{"pos":1,"rank":12},21:{"pos":2,"rank":22}.........n:{"pos":n,"rank":n}}}

Then you can directly fetch it using object[ur_id].pos
