If you want to parse the response text as JSON, first you have to send JSON in the response.

JSON Lint is a useful tool for debugging this sort of thing.

This is not valid JSON:

{ "code": 00 }

The Number data type in JSON cannot begin with a double zero.

Numbers in JSON

After you fix the response, the success function will fire, and data will be the result of parsing the JSON.

The data parameter is already an object, so you can just use it as object. If you prefer to get the JSON string for whatever reason, use JSON.stringify(data) to get the JSON string.
