I am having the JSON array of objects like below,
let data = [
{
"node":[
{
"name":"aaaaa",
"count":"2",
}
]
},
{
"client":[
{
"name":"bbbbb",
"count":"2",
}
]
},
{
"ip_address":[
{
"name":"ccccc",
"count":"3",
}
]
},
{
"compute":[
{
"name":"dddd",
"count":"1",
}
]
}
]
let find_key = "ip_address";
Need to check whether the root key is exists or not(for example need to find ip_address
is exists or not). without foreach please.

Tried the following ways but no luck. Some help would be appreciated. Thanks in advance. Tried like below, but its not working (always returning false
),
console.log(data[0].has(find_key)); // false
console.log(data.has(find_key)); // false
console.log(data[0].hasOwnProperty(find_key)); // false
You can try with array.some()
:
let exists = data.some(x => x[find_key]);
let data = [ { "node":[ { "name":"aaaaa", "count":"2", } ] }, { "client":[ { "name":"bbbbb", "count":"2", } ] }, { "ip_address":[ { "name":"ccccc", "count":"3", } ] }, { "compute":[ { "name":"dddd", "count":"1", } ] } ] let find_key = "ip_address"; let exists = data.some(x => x[find_key]); console.log(exists);
You have an array of objects, and _.has()
an the in
expect as single object. Right now you check if the array has a key called ip_address
, which it doesn't. Use Array.some()
or lodash's _.some()
, and check if each object has the key:
const data = [{"node":[{"name":"aaaaa","count":"2"}]},{"client":[{"name":"bbbbb","count":"2"}]},{"ip_address":[{"name":"ccccc","count":"3"}]},{"compute":[{"name":"dddd","count":"1"}]}] // vanilla JS const result1 = data.some(o => 'ip_address' in o) console.log(result1) // lodash const result2 = _.some(data, o => _.has(o, 'ip_address')) console.log(result1)
