Is there a more elegant javascript way to get the body1 and body2 subkeys from the collision dictionary?

In the example below, collision_names is an array containing all the collisions in which I'm interested. I create that array by concatenating the names of the two objects together in all permutations (ugh!). For any one of 10 objects hitting any one of 2 objects, that yields 40 potential names (10 x 2 x 2). It seems that Max doesn't makes two collision names for the same two objects...but I don't know which order that Max might concat it.

Once I have that array, then when I get the collision dictionary out of the right outlet of jit.phys.world, I send it to a js object containing this snippet of code...

        if (collision_names.indexOf(keys[a]) >= 0)

            var subkeys = d.get(keys[a]);

            for (asubkey in subkeys)

                var subd = new Dict(subkeys[asubkey]);

                post(subd.get("body1") + " hit " + subd.get("body2"));

function collisions()
{
	var d = new Dict(arguments[1]);
	var keys = d.getkeys();

	for (var a=0; a
	{
		if (collision_names.indexOf(keys[a]) >= 0)
		{
			post(keys[a]);
			post();
			var subkeys = d.get(keys[a]);
			for (asubkey in subkeys)
			{
				var subd = new Dict(subkeys[asubkey]);
				post(subd.get("body1") + " hit " + subd.get("body2"));
				post();
			}
		}
	}
}
