How to remove an array object item in javascript?

Question

How to remove an array object item in javascript?

Here is my code

var array = [{ id: 1,  name: 'test' }, { id: 2,  name: 'test2' }];

I need above array to be changed like below

[{ name: 'test' }, { name: 'test2' }]

I tried with delete

array.forEach(function(arr, i) {
    delete array[i].id;
});
console.log(array);

Outputs as

[ { id: 1, name: 'test' },
  { id: 2,  name: 'test2'} ]

But it doesn't remove the id item. How to remove array object item?

I am using this in node v0.8.

Answer 1

The id property is deleted, as can be demonstrated by:

for (var l in array[0]) {
    if (array[0].hasOwnProperty(l)) {
        console.log(array[0][l]);
    }
}

See jsFiddle

Hm, here is your code with jQuery 1.9.1 and it works good: http://jsfiddle.net/8GVQ9/

var array = [{ id: 1,  name: 'test' }, { id: 2,  name: 'test2' }];
array.forEach(function(arr, i) {
    delete array[i].id;
});
console.log(array);

By the way, you would like to delete 'property' Id from objects in array- that's better to understand you.

You have to parse the array and build the new version then replace it.

var array = [{ id: 1,  name: 'test' }, { id: 2,  name: 'test2' }];    
var tempArray = []; 
    for(var i = 0; i < array.length; i++)
    {
        tempArray.push({name : array[i].name});
    }
    array = tempArray;
