Why doesn’t deleting from a Javascript array change its length?

Question

I have an array:

data.Dealer.car[0]
data.Dealer.car[1]
data.Dealer.car[2]

If I do this:

alert(data.Dealer.car.length);
dele         


        

Answer 1

Ok.. fixed this now as the array was still allocated.

I needed to basically do:

var newCar = new Array();
for (i = 0 ; i < tblSize -2; i ++)
{
    newCar[i]=data.Dealer.car[i];
}
data.Dealer.car = newCar;
