I have an api data
current: {
errors: {},
items: {
Economy: {}
}
}
Object key "Economy" can be different, for instance "Advance"
and i call it like
let current = current.items.Economy
or let current = current.items.Advance
How can i call it dynamically? P.S. My front don't know what key will be return
Use Object.entries to get every key and value pair in an object. If items only has one such key-value pair, then just select the first entry:
const obj = {
current: {
errors: {},
items: {
Foo: {data: 'foo data'}
}
}
};
const [key, val] = Object.entries(obj.current.items)[0];
console.log(key);
console.log(val);If you don't actually care about the dynamic key name and just want the inner object, use Object.values instead.
You can use Object.keys(current.items).
let current = {
errors: {},
items: {
Economy: {age: 10}
}
}
let keys = Object.keys(current.items);
let currentVal = current.items[keys[0]];
console.log(currentVal);You can also use for loop:
let current = {
errors: {},
items: {
Economy: {age: 10}
}
}
for(var key in current.items){
console.log(current.items[key]);
}
