Converting a JS object to an array using jQuery

My application creates a JavaScript object, like the following:

myObj= {1:[Array-Data], 2:[Array-Data]}

But I need this object as an array.

array[1]:[Array-Data]
array[2]:[Array-Data]

So I tried to convert this object to an array by iterating with $.each through the object and adding the element to an array:

x=[]
$.each(myObj, function(i,n) {
    x.push(n);});

Is there an better way to convert an object to an array or maybe a function?
