Question

I am attempting to parse the incoming JSON from XBMC (Eden Beta v3), an example string from XBMC is as follows:

{"jsonrpc":"2.0","method":"Player.OnPlay","params":{"data":{"item":{"type":"movie"},"player":{"playerid":1,"speed":1},"title":""},"sender":"xbmc"}}

I am using json2.js from https://github.com/douglascrockford/JSON-js/blob/master/json2.js to give me the JSON.parse and JSON.stringify functions in my application.

I am using the parse function in my code like this

var temp = JSON.parse(data);

Which is working fine for the first two properties, “jsonrpc” and “method”… so I can access those like this

temp.method

returns “Player.OnPlay”

temp.jsonrpc

returns “2.0”

However, if you look at the string sent by XBMC, it also contains what they refer to as “extended parameters” or “params”, I cannot seem to track down what the JSON parser is doing with the rest of the message, or how I can access them in similar ways as the first two properties. If I try

params = temp.params

or any other way of accessing the params property, I get an Undefined error as there is no such property in the JSON object… I hope this is clear enough for someone to take a stab at helping me out. Will provide any extra info needed…

Thanks

The value of params in the JSON data is an object, so you have to access the sub-properties of that.

temp.jsonrpc
temp.method
temp.params["data"]["item"]["type"]
temp.params["data"]["player"]["playerid"]
temp.params["data"]["player"]["speed"]
temp.params["data"]["item"]["title"]
temp.params["sender"]
