How can I return a variable from a $.getJSON function

Question

I want to return StudentId to use elsewhere outside of the scope of the $.getJSON()

j.getJSON(url, data, function(result)

If you wish delegate to other functions you can also extend jquery with the $.fn. notation like so:

var this.studentId = null;

$.getJSON(url, data, 
    function(result){
      $.fn.delegateJSONResult(result.Something);
    }
);

$.fn.delegateJSONResult = function(something){
  this.studentId = something;
}
