Javascript array converted to JSON objects instead of array

I am trying to submit some JSON to my web app and I want the JSON to be like this:

{ 
  "thing1" : 
  {
    "something" : "hello"
  },

  "list_of_things" :
  [
   {
     "item1" : "hello"
   },
   {
     "item2" : "hello"
   }
  ]
}

Here I have one JSON object and a JSON array that holds JSON objects. When I create the data to submit in Javascript I do:

form = {
  "thing1" : {
    "something" : somethingVariable
  },
  "list_of_things" : listArray
}

Here 'listArray' is a Javascript Array object of Javascript hash objects. I submit this using jQuery's ajax method but instead of javascript array displaying as the JSON array desired it converts it to a series of JSON objects like this:

{ "1" : { "thing1" : "something" }, "2" : { "thing2" : "something" }...

How can I get the array to be submitted as an array rather than be converted into a series of JSON objects with the array indexes as keys?

EDIT#1: 'listArray' is a simple Javascript array that is defined like so:

var listArray = new Array();
listArray.push({ "thing1" : "something" });
listArray.push({ "thing2" : "something" });

EDIT#2: 'form' is sent to the server with the following call:

$.ajax({
  type: 'POST',
  url: '/url',
  dataType: "json",
  data: form,
  success: function(data) {
    /* success code here */
  }
});

Have a look here. If you are truly trying to post JSON you will need to send the string, not an object literal. You could use JSON.stringify (or a more supported JSON solution) on form.

$.ajax({
    url: "/url",,
    dataType: "json",
    type: "POST",
    processData: false,
    contentType: "application/json",
    data: JSON.stringify(form)
});
