I have the following object:
objTeste = [
{
"id": "03",
"nome": "teste03",
"pai": {
"id": "02",
"nome": "teste02",
"pai": {
"id": "01",
"nome": "teste01"
}
}
}
]
I want to remove all IDs from this object with JavaScript, I have already tried with for but not able to delete the last ID. Can anyone help me?
This objTest is an array of objects. To remove depth properties in a precise object from a recursive function, that is: to call itself to each sub-level to object.
I created one that verifies if a property is a sub-level (another object) and if not, it checks to see if the property is id . If it is to be deleted.
function recursiva(obj) {
for (var k in obj) {
if (typeof obj[k] == "object" && obj.hasOwnProperty(k)) recursiva(obj[k]);
else if (k == 'id') delete obj.id;
}
}
objTeste.forEach(recursiva);
In this case you do not even need to use .map because once you change the object inside the array it changes directly in the original.
If you want to create a new array, with new objects (without the ID) you can do this:
function recursiva(obj) {
var _obj = {};
for (var k in obj) {
if (typeof obj[k] == "object" && obj.hasOwnProperty(k)) _obj[k] = recursiva(obj[k]);
else if (k != 'id') _obj[k] = obj[k];
}
return _obj;
}
var novo = objTeste.map(recursiva);
console.log(JSON.stringify(novo)); // [{"nome":"teste03","pai":{"nome":"teste02","pai":{"nome":"teste01"}}}]
