Here's the quick version of the code as it stands right now:
function foo(attributeName, someJSObj, key, newValue)
{
someJSObj[key].attributeName = newValue;
}
Obviously this doesn't work, since it just creates a new element called attributeName. Is there an easy way to dereference the attributeName into the string that represents some existing attribute on someJSObj?
