How can I remove an element using its position of an object? I for example want to remove the second one.

Object {duur: ".short", taal: ".nl", topic: ".algemeen-management"}

How can I remove an element using its position of an object? I for example want to remove the second one.

• javascript
• jquery
• object

• 1 Properties are not ordered. You cannot reliably say which one is the "second" property. – Felix Kling Commented Jan 5, 2017 at 15:04

The Object.keys() will give you in the order of how it is defined. Always it is better to remove based on the key name. Because, in an object, the keys are not exactly sorted and they don't have any order.

var obj = {
  duur: ".short",
  taal: ".nl",
  topic: ".algemeen-management"
};
console.log(obj);
var position = 2;
delete obj[Object.keys(obj)[position - 1]];
console.log(obj);

The best and right way to do is to remove by the key name:

var obj = {
  duur: ".short",
  taal: ".nl",
  topic: ".algemeen-management"
};
console.log(obj);
var key = "taal";
delete obj[key];
console.log(obj);

like this :

var index = 1 ; // the position you want minus 1

var example = {duur: ".short", taal: ".nl", topic: ".algemeen-management"}

delete example[Object.keys(example)[index]];

Better use the delete operator like this:

delete myObject.taal;

You can siply use : delete(object.taal).
