jQuery Function to Serialize Object, like in a PHP $_POST request from HTML, the main issue came with combining checkboxes & hidden inputs, and I've made this adaptation to handle this..

main.js

  $.fn.wpepSerializeObject = function () {
    "use strict";

    var result = {},
        objectInstance = this;

    var extend = function (i, element) {
      var node = result[element.name];

      if ('undefined' !== typeof node && node !== null) {
        if ($.isArray(node)) {
          node.push(element.value);
        } else {
          result[element.name] = [node, element.value];
        }
      } else {
        result[element.name] = element.value;
      }
    };

    $.each(this.serializeArray(), extend);

    // Lets make this ACT like a true PHP Request, seems like there's no famous post to include this.
    jQuery.each( result, function( key, value ) {
      if( ! ( value instanceof Array ) )
        return;

      if( key.endsWith("[]" ) )
        return;

      var checked_input = objectInstance.find( 'input[name="' + key + '"]:checked' );

      if( checked_input.length > 0 ) {
        result[key] = checked_input.val();
      }

      var hidden_input = objectInstance.find( 'input[name="' + key + '"][type="hidden"]' );

      if( hidden_input.length > 0 ) {
        result[key] = hidden_input.val();
      }
    });

    return result;
  };
