Using javascript script with json format data

ASP.NET

I have created a SCORM API for our LMS and right now I am using hard coded userID (variables that reference things in the database). I need to pass the real userID instead of using hard coded ones. I know the userID is stored in the session.Now by using session id i have to fetch all data of user from usertable dynamically and shows that data on my server. My data is in json format which is given below(tin is object of my service)

How do I get these into JavaScript so I can include them in my service.

 test = function () {

   tin.sendStatement(
            {
                actor: {
                    name: "sk",
                    mbox: "mailto:abcd@gmail.com",
                    objectType: "Agent"
                },
                verb: {
                    id: "http://adlnet.in/expapi/verbs/passed",
                    display: {
                        "en-US": "succedd"
                    }
                },

                object: {
                    id: "http://example.adlnet.in/xapi/example/CBT",
                    definition:
                 {
                     name:
                 {
                     "en-US": "I am sk Sharma"
                 },
}
