This is my first use of jquery and json so would be grateful for any feedback please.

Background - this is on a job listing site and it has a Linkedin apply button plugin - this provides for a callback the someone has applied for a job. So I write the callback function which extracts the Job ID (a primary key in my database) and makes an ajax call to record that this Job ID has been applied for.

The Linkedin plugin is described here:

https://developer.linkedin.com/apply-processing-applications

But essentially it passes this json object to the callback:

{
   "event":"success",
   "job":{
      "companyID":"12345",
      "jobID":"9876",
      "jobTitle":"Chief Cat Herder"
   }
}

And advice I got on stackoverflow

Anyway the code, which is placed within the head of the page.

<script type="text/javascript">
function linkedInApplySuccess(jsonReturnObj) 
    {
    // no need to use any jquery json functions as already jabe a json object from linkedin (instead os a string)
    // see second answer here http://stackoverflow.com/questions/3569416/parsing-json-string-with-jquery-parsejson

    var job_id = jsonReturnObj.job.jobId;

    $.ajax({
        url: "/php/cv_db/ajax_log_linkedin_application.php",
        data: {job_id: job_id},
        type: "POST"
        });

    };
</script>

Note re the ajax, I am not looking for any return data and nor do I care about success or failure as should it fail, I'm not going to ask someone to apply for the job again. I do have error logging in my PHP file though.
