Question

var sv_defaultArray = new Array([]);

    sv_defaultArray[0] = "post 1";
    sv_defaultArray[1] = "post 2";
    sv_defaultArray[2] = "post 3";

Console states the array here is [“post 1”, “post 2”, “post 3”];

var myJsonString = JSON.stringify(sv_defaultArray);

Console states the array here is [“post 1”, “post 2”, “post 3”];

  $.post("http://www.foobar.com/write.php", { 'array': myJsonString });

Array is posted as: [\”post 1\”,\”post 2\”,\”post 3\”]

What is going wrong, why is the data not getting converted to json and submitted as json too?

When i call the databack i am calling it as jsonp wrapped in a callback function

You have forgot to set dataType on $.post

$.post("http://www.foobar.com/write.php", 
    { 'array': myJsonString }, 
    function(){/* handle results here */},
    "json"
);

Anyway, you have plain Array, so it will be decoded the same way. If you need {} you have to encode associative array or object.

var data = {field1: 'data1', field2:'data2'};
//or
var data = new Array();
data['field1'] = 'data1';
data['field2'] = 'data2';
