Question

How can I send data in JSON format to an AJAX POST request.
My data consists of a JAVA person object with many attributes like name,dob,address,phone etc,
a list of Suppliers(supplier name, number) to this person, another list of helpers (helper name, number).
How do I combine all the data into a JSON object and send it in jQuery.post(url, data) ?

You can build a complex JSON object and submit that to the server.

var employees = { "accounting" : [   // accounting is an array in employees.
                                { "firstName" : "John",  // First element
                                  "lastName"  : "Doe",
                                  "age"       : 23 },

                                { "firstName" : "Mary",  // Second Element
                                  "lastName"  : "Smith",
                                  "age"       : 32 }
                              ], // End "accounting" array.                                  
              "sales"       : [ // Sales is another array in employees.
                                { "firstName" : "Sally", // First Element
                                  "lastName"  : "Green",
                                  "age"       : 27 },

                                { "firstName" : "Jim",   // Second Element
                                  "lastName"  : "Galley",
                                  "age"       : 41 }
                              ] // End "sales" Array.
            } // End Employees
