Request response doesn't work

Here is my JSON function:

function createjson(){
  var json='{"jsondata":[[';
  $("#kup td").each(function(){
  if($(this).html()!="")
  {
    json+= parseInt($(this).html())+",";
    if($(this).index()%5==0 && $(this).index()!=0){
      json=json.substring(0,json.length-1);
      json+="],["
    }                       
  }             
 });
json=json.substring(0,json.length-3);
json+="]]}";
console.log(json); //-> works fine.
return json;
};

The AJAX part:

$("#button").click(function(){
  $.ajax({
    type:"POST",
    url:"x.php",
    data: createjson(),
    contentType: "application/json",
dataType: "json",
    success: function(result) {
        alert("done"); //->works
    }
  });           
});

The PHP part:

<?php
   header('Content-type: application/json');
   echo "<pre>";
   echo    $_POST['jsondata'];
   echo "</pre>";
?>

So, the "alert" works but when check the response in console, it returns only "<pre></pre>"

any solution?

The data option can contain either a query string of the form key1=value1&key2=value2, or an object of the form {key1: 'value1', key2: 'value2'}. If the latter form is used, the data is converted into a query string using jQuery.param() before it is sent. This processing can be circumvented by setting processData to false

. from jquery API doc

I didn't tested it but should give the intense how to change structure, give it a try:

function createdata(){
  var data;
  $("#kup td").each(function(){
    if($(this).html()!="")
    {
      data.push( parseInt( $(this).html() ) );
      //...                    
    }             
  });
console.log(data);
return data;
};

$("#button").click(function(){
  var data = createdata();
  $.ajax({
    type:"POST",
    url:"x.php",
    data: {createjson:data},
    contentType: "application/json",
    dataType: "json",
    success: function(result) {
        alert("done"); //->works
    }
  });           
});
