Parsing JSON params. in submitSuccess function

I have a (possibly stupid) question about how to use the objects that are passed as parameters to submitSuccess in Editor, specifically, and other Datatables/Editor parameters generally.
The documentation shows the submitSuccess function as
function( e, json, data, action )
In order to get the value of a property, say 'vlots.lot_status' , from the 'data' parameter, I use simple object notation:
data.vlots.lot_status
But the 'json' object appears more convoluted, and to get the same property value from the 'json' object. I see from the structure of the object that I have to use
json.data[0].vlots.lot_status
I have 2 questions,
1. Is there a more direct way to address the properties in object 'json'
2. If not, is the structure of these parameter objects documented somewhere, or recommendations on how to parse them? It is not clear to me how to use some of the parameters in other functions/callbacks, and I wonder if I am missing something.
Many thanks.

Hi,
Yes, the JSON response from the server is a little more complex because of Editor's multi-row editing capabilities. You would need to loop over the
json.dataarray if you are wanting to access the row data there.Can I ask what you want to do with it there? I'm just wondering if there might be a different option.

Thanks Alan. I have not been using muti-row editing, but now I see how this requires the json.data[] array.
To answer your question, I ended up using the 'data' parameter quite satisfactory, but I realized that I didn't really understand how these data structures are parsed.
I checking the server data after an Update, against the original datatable data, so that I can highlight the background of any cell that the user changes. My Editor form contains a couple of input fields, but it is useful for the user to see which dataTable field was actually changed by the Update.
Sounds like a good use of it! Thanks for the update.
