Dojo XhrPost set name for posted json object on server - ajax

Question

I have a Dojo ajax request and i am posting the data as json however the data is not reaching the server in json format. I am also not able to see the JSON tab in the browsers Net option of the console. I need the data in json format on the server.
Ajax Request
var someData = [{id:"1",age:"44",name:"John"},
{ id:"2",age:"25",name:"Doe"},
{ id:"3",age:"30",name:"Alice"}];
function SendData() {
var xhrArgs = {
url:'processData',
postData: someData,
handleAs: "json",
headers: { "Content-Type": "application/json", "Accept": "application/json" },
load:function(data){
console.log('data was posted');
},
error:function(error){
console.log(error);
}
};
dojo.xhrPost(xhrArgs);

I would like the JSON data under to appear in the following format under with the name MyData. How is this format possible on the server?
JSON
MyData [Object{id:"1",age:"44",name:"John"},
Object{ id:"2",age:"25",name:"Doe"},
Object{ id:"3",age:"30",name:"Alice"}]
SOURCE
{"MyData":[{id:"1",age:"44",name:"John"},
{ id:"2",age:"25",name:"Doe"},
{ id:"3",age:"30",name:"Alice"}]}

Answer 1

Actually url:'' is empty in your Ajax call. Please provide action url,
for suppose
url: "AddTrackServlet"

Answer 2

After playing around with the variable i saw it could be declared
var someData = [{id:"1",age:"44",name:"John"},
{ id:"2",age:"25",name:"Doe"},
{ id:"3",age:"30",name:"Alice"}];
var formData = {MyData:someData}
function SendData() {
var xhrArgs = {
url:'processData',
postData: dojo.toJson(formData),
handleAs: "json",
headers: { "Content-Type": "application/json", "Accept": "application/json" },
load:function(data){
console.log('data was posted');
},
error:function(error){
console.log(error);
}
};
dojo.xhrPost(xhrArgs);
