从JSON文件访问和搜索数据

Question

If I have the JSON object below

 {
    "animals":{     
        "a_1":{    
        "species":"Tiger",     
        "name":"Timmy",     
        "dob":"2016-03-12",       
        },    
        "a_2":{    
        "species":"Lion",     
        "name":"Leo",     
        "dob":"2012-12-04",           
        }   
    }    
} 

How do I search to return

"a_1": {    
    "species":"Tiger",     
    "name":"Timmy",     
    "dob":"2016-03-12",       
},    

for the search a_1 ?

Is there a similar way to call a_1 / a_2 , etc?

Answer 1

I think you should change your data structure to an array. It would be easier:

 const data = { "animals": { "a_1": { "species": "Tiger", "name": "Timmy", "dob": "2016-03-12", }, "a_2": { "species": "Lion", "name": "Leo", "dob": "2012-12-04", } } } const animalList = Object.keys(data.animals).map(key => ({ key, item: data.animals[key] })) const searchName = input => animalList.filter(animal => animal.item.name === input); console.log(searchName('Leo')) 

Answer 2

You can directly search by Key.

For example:

var data = {
    "animals":{     
        "a_1":{    
            "species":"Tiger",     
            "name":"Timmy",     
            "dob":"2016-03-12",       
        },    
        "a_2":{    
            "species":"Lion",     
            "name":"Leo",     
            "dob":"2012-12-04",           
        }   
    }    
};

var searchKey = "a_1";
console.log(data["animals"][searchKey]);
