how can I change the "ABC" field in the code below?
var data = {ABC:{key:'dynamic_key',value:'dynamic_value'}}
Normally, I can give the value I want by saying data.ABC.key, but what I really want is to go as data.CCC instead of data.ABC, so I just want to change the ABC name.
Re-assign the inner object to the new outer object key, then delete the previous.
var data = {ABC:{key:'dynamic_key',value:'dynamic_value'}}
data.CCC = {...data.ABC}
delete data.ABC
console.log(data)var data = {ABC:{key:'dynamic_key',value:'dynamic_value'}}
data = {CCC: data.ABC}
console.log(data)EDIT... It you want to use a string from a variable to set the new key, use the bracket notation:
var data = {ABC:{key:'dynamic_key',value:'dynamic_value'}}
var newKey="CAR"
data[newKey] = data.ABC
delete data.ABC
console.log(data)data.CCC = data.ABC // on object create new key name. Assign old value to this
delete data.ABC //delete object with old key name
output:
{
"CCC":
{
"key": "dynamic_key",
"value": "dynamic_value"
}
}
