I've following output code
I want to remove position from array. When I try delete $products.position;
It is not deleting. But When I try delete $products[0].position;
It is deleting only from first.

As you already know
$products
is an array, so iterate and usedelete
operator. You should search "How to iterate an array?" – Satpal Commented Jun 14, 2017 at 6:01 - luckily this isn't JSON, but a palin ol' javascript Object - doing this with JSON would be painful – Jaromanda X Commented Jun 14, 2017 at 6:07

Reset to default 5Loop through the elements of the array and delete position
from each.
for (var i = 0; i < $products.length; i++) {
delete $products[i].position;
}
I would use map
instead of forEach
.
const products = [{ foo: 'bar', position: 1 }, { foo: 'baz', position: 2}, { doo: 'daz' }];
console.log(products.map(obj => delete obj.position && obj));
.as-console-wrapper { max-height: 100% !important; top: 0; }
Although it is probably less readable it makes more sense to me because you want to generate a new array applying a delete
function to each element.
try this
$products.forEach(function(item){
delete item.position;
});
There are multiple methods to remove an JSON object from particular position from an array, but I will remended to use splice method since its paratively faster then other methods.
products.splice(position, 1);
The first parameter indicates the position to start from and the second indicates the number of objects you want to splice. Since you only want to remove one object, so it should be written 1(one). Position here starts from 0(zero) so insert the position accordingly.
This one works for me.
for(var i in $products){
delete $products[i].position;
}
