Ajax Question

Submit form input array with jquery ajax post

Alright I want to submit a form thru jquery ajax. All the inputs are in an array and it is multidimensional.

Its a dynamic form that uses the array key as the question id.
The subkey is used for grouping the questions at a question set.

<form name="testing" id="testing" method="post">
<label>Question 1?</label>
<input type="text" name="data[14][1]" id="" class="" value=""><br>
<label>Question 2?</label>
<input type="text" name="data[16][1]" id="" class="" value=""><br>
<label>Question 1?</label>
<input type="text" name="data[14][2]" id="" class="" value=""><br>
<label>Question 2?</label>
<input type="text" name="data[16][2]" id="" class="" value=""><br>
<label>Question 3?</label>
<select name="data[19]" id="" class="">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<input type="submit" value="Submit">

So that is my example html. Here is my example jquery:

$("#testing").submit(function() {
var data = $('input[name^="data\\["]').serializeArray();
type: "POST",
url: "upload.php",
data: {internalform: "submit", data: data},
dataType : "text",

success: function(returndata){
if(returndata == "no")
{ return false;
} else {
alert("clicked 1 " + returndata);
return false;

Problem is I get this as a return array:

[0] => Array
[name] => data[14]
[value] => sd

[1] => Array
[name] => data[16]
[value] => s


But I want an array like this:

Array ( [14] => ddd [16] => ddd [19] => 4 )

Im sure its simple but I'm missing something. I know why its doing it but I can't get it the way I want it/need it. Can someone help?

Try below snippet,I have not tested this but probably it should work.

Replace var data = $('input[name^="data\\["]').serializeArray(); part with below snippet

var data = {};
$.each($('input[name^="data\\["]')​.serializeArray()​, function() {
    data[] = this.value;

Try this it will solve the data coming in front issues

i have worked out this one

var data = {};
$.each($('select[name^="data\\["] , input[name^="data\\["]').serializeArray(), function() {
   var vv =, '' ).replace(/(\[[0-9]\])$/,'');
   data[vv] = this.value;
