Excluding properties in toJSON/toJS?

[Johan Nordberg]

Is there a way to exclude properties from being serialized with toJSON? I think I've read somethere that the mapping plugin might handle this?

The problem I have is that a model with children[] / parent properties have circular references when serializing. I'd like to exclude the parent from being serialized.

The way I've handled this is using ko.toJS() and deleting the
properties I don't want included.

var tvModel = ko.toJS( viewModel );
delete tvModel.app_name_values;
delete tvModel.common_items.background_image_values;
// ...
var json = JSON.stringify( tvModel, null, 4 ));

I filter my objects with a helper function and an empty reference
object, initially rendered by the server:
function filterObj(obj, filter)
{
var result;
if(typeof obj === "object")
{
result = {};
for(key in obj)
{
if(filter[key] !== undefined)
{
result[key] = filterObj(obj[key], filter[key]);
}
}
}
else
{
result = obj;
}
return result;
}

var filtered = filterObj(data, emptyDataObject);

// convert and send filtered data object(s)
