Accessing API JSON response value

Question

I've got this json object via an API.

var servers = {   
    'd22ab1': { 
        condition: 'autorebooted',
        name: 'acb1'
    },
    '6946e0': { 
        condition: 'online',
        name: 'abc2'
    }
}

for (var server in servers) {
    console.log(server.condition);
}

I'm trying to get the condition value but my for loop doesn't work as i expected. what am I missing? Thank you!!!

Answer 1

You need to access via server key as you iterate over keys.

 var servers = { 'd22ab1': { condition: 'autorebooted', name: 'acb1' }, '6946e0': { condition: 'online', name: 'abc2' } } for (var server in servers) { console.log(servers[server].condition); } 

Or you can use Object.values , which returns values of each property.

 var servers = { 'd22ab1': { condition: 'autorebooted', name: 'acb1' }, '6946e0': { condition: 'online', name: 'abc2' } } Object.values(servers).forEach(item => console.log(item.condition)); 

Answer 2

servers is not iterable, use Object.values

Object.values( servers ).forEach( s => console.log( s.condition ) )

Demo

 var servers = { 'd22ab1': { condition: 'autorebooted', name: 'acb1' }, '6946e0': { condition: 'online', name: 'abc2' } }; Object.values( servers ).forEach( s => console.log( s.condition ) ) 

Answer 3

Use Object.keys on server to get all the keys. Then iterate over the keys and get conditions from each.

 var servers = { 'd22ab1': { condition: 'autorebooted', name: 'acb1' }, '6946e0': { condition: 'online', name: 'abc2' } } let conditions = Object.keys(servers).map(key => servers[key].condition); console.log(conditions)
