Convert associative array to numeric array

Question

I have the following associative array structure in JavaScript

Array (
    [-1] => Array (
        catId : -1
        [subCatId] => Array (
             subCatId : -3
            [0] => Array (
                property : value
            )
            [1] => Array (
                property : value
            )
        )
    )
    [-4] => Array (
        catId : -4
        [subCatId] => Array (
             subCatId : -6
            [0] => Array (
                property : value
            )
            [1] => Array (
                property : value
            )
        )
    )
)

I want to convert this into numeric Array, like this

Array(
    [0] => Array(
        catID : -1
        [subCatId] => Array (
             subCatId : -3
            [0] => Array (
                property : value
            )
            [1] => Array (
                property : value
            )
        )
    )
    [1] => Array(
        catID : -4
        [subCatId] => Array (
             subCatId : -3
            [0] => Array (
                property : value
            )
            [1] => Array (
                property : value
            )
        )
    )
)

I have tried using,

var numeric_array = new Array();
for (var items in Array){
    numeric_array=Array[items];
}

but its not achieving my required result, any suggestions or comments are greatly appreciated.

try this:

var numeric_array = new Array();
for (var items in Array){
    numeric_array.push( Array[items] );
}

btw, I'm not sure Array is good name for you entire array:

var hash_array = []; // array which you have
...
var numeric_array = [];
for ( var item in hash_array ){
    numeric_array.push( hash_array[ item ] );
}
