JS - Generic Parse JSON Response

Question

I have a JQ/JS function that creates an AJAX request, and returns a JSON result.

 function ajaxRequest(url, callback){
                        $.ajax({
                              url: "Data/"+url,
                              type : 'GET',
                              contentType: "application/json",
                              success: function( resp ) {
                                       callback(resp );
                                   }
                          });
                          }

Currently this passes the whole response to my callback function.

How can I parse this for just the JSON object.

Each JSON object is different, they are a single level object, but each with different parameter names.

I was wondering if there is a generic way to pass just the json object.

Typically, I would use:

resp.ObjectName

but I want to make this generic, for instances where I do not have ObjectName.

Please try the dataType option instead of contentType :

function ajaxRequest(url, callback){
                        $.ajax({
                              url: "Data/"+url,
                              type : 'GET',
                              dataType: "json",
                              success: function( resp ) {
                                       callback(resp );
                                   }
                          });
                          }

You need to use $.parseJSON for parsing json result:

function ajaxRequest(url, callback){
                    $.ajax({
                          url: "Data/"+url,
                          type : 'GET',
                          dataType: "json",
                          success: function( resp ) {
                             var response = $.parseJSON(resp)
                                   callback(response);
                               }
                      });
                      }
