var spConfig = new Product.Config({"attributes":{"85":{"id":"85","code":"color","label":"Colour","options":[{"id":"9","label":"Black","price":"0","oldPrice":"0","products":["12","13"]}.....

I need to be able to get the  "products" (in this case 12,13) by the  options id, in this case 9.

At the moment the code I have just itterates through,

var options = this.config.attributes[attributeId].options;
for(var i=0;i<options.length;i++){
alert(options[i].price);
}
