Trying to sort a custom JavaScript object

Question

I\'m not too good at JS, but have survived thus far. I\'m creating a sort-of complex JS object and wanting to sort it. The object\'s structure looks like this:

<

Ok from the comments below I got a clearer picture of what the object is.

Assuming the object looks like this:

cart.attributes = {
    '46913872:2:Size' : 10,
    '46913872:2:Hollow-to-Hem' : 57
    // ...
}

It can't be sorted since it's not an Array. But you can sort it out for printing.

In plain old javascript you can do:

// First get all keys:
var keys = [];
for (var n in cart.attributes) {
    if (cart.attributes.hasOwnProperty(n)) {
        keys.push(n);
    }
}

// now sort the keys:
keys.sort(function(a,b){
    attr_a = a.split(':');
    attr_b = b.split(':');

    // sort by product ID:
    if (parseInt(attr_a[0],10) < parseInt(attr_b[0],10)) return -1;
    if (parseInt(attr_a[0],10) > parseInt(attr_b[0],10)) return 1;
    // sort by quantity:
    if (parseInt(attr_a[1],10) < parseInt(attr_b[1],10)) return -1;
    if (parseInt(attr_a[1],10) > parseInt(attr_b[1],10)) return 1;
    // finally sort by name:
    if (attr_a[2] < attr_b[2]) return -1;
    if (attr_a[2] > attr_b[2]) return 1;
    return 0;
})

// now print out the object in key-sorted-order:
for (var i=0; i
