For example:

var Cars = {

    1: { Make: Honda,

         Model: Accord,

         Color: Red

    },

    2: { Make: Honda,

         Model: Civic,

         Color: Silver

    },

    3: { Make: Honda,

         Model: Jazz,

         Color: Yellow

    }

If I do a delete.Cars[2]; I will be left with Cars[1] and Cars[3].

I need a way (JS or jQuery) so that when I delete a key, the object reindexes. So, in the example above, I'm left with Cars[1] and Cars[2] (which was Cars[3]).

That is because you dont need the keys for the array.

var Cars = [

    {

        Make: Honda,

        Model: Accord,

        Color: Red

    },{

        Make: Honda,

        Model: Civic,

        Color: Silver

    },{

        Make: Honda,

        Model: Jazz,

        Color: Yellow

    }

];



alert(Cars[1]['Make']); // Honda
