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.
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

id is not deleting.
array variable ran through the node.exe interpreter. The top shows the code, the bottom half the result. It only shows test, which is the value of the only (own) property of object contained by array[0], so the id property is removed.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;
v0.8.14and I'm seeing the correct behaviour, i.e. the id element is gone. Apologies if I'm asking the obvious, but is the code above the code that you're actually running?console.log(array), i.e.[{ name: 'test' }, { name: 'test2' }]. I'd be surprised if the native array object's behaviour had been changed between these two versions.
