使用 Ajax 将表单数据发布到 ZF2 控制器

The question is that I don't understand how/where ZF2 posts form data when a submit button is pressed. So, when I do
if ($this->getRequest()->isPost()){
after the ajax call below, it tells me that no data has been posted.

When I do the above isPost() if statement it works perfectly when I hit the submit button, telling me the data has been posted and subsequently telling me that the form data is valid.

这里是ajax调用-

            <script>
                $.ajax({
                    url: urlform,
                    type: 'POST',
                    dataType: 'json',
                    contentType: "application/json; charset=utf-8",
                    async: true,
                    data: ($("#newThoughtForm").serialize() + '&submit=go'),
                    success: function () {
                        console.log('SUBMIT WORKS');
                        setTimeout(function () { <?php echo $this->invokeIndexAction()->test(); ?> ;
                        }, 1000);
                    },
//This keeps getting executed because there is no response, as the controller action is not run on a Post()
                    error: function () {
                        console.log('There is error while submit');
                        setTimeout(function () { <?php echo $this->invokeIndexAction()->test(); ?> ;
                        }, 1000);
                    }
//I assume the data won't get pushed to the server if there is no response,
//but I can't figure out how to give a response in ZF2 since the controller is not
//run when the Post() is made. 
                });

这是表格-

            use ZendFormForm;

            class newAlbumForm extends Form
            {
                public function __construct()
                {
                    parent::__construct('newAlbumForm');
                    $this->setAttribute('method', 'post');

                    $this->add(array(
                        'type' => 'AlbumModuleForm
ewAlbumFieldset',
                        'options' => array(
                            'use_as_base_fieldset' => true
                        )
                    ));

                    $this->add(array(
                            'name' => 'submit',
                                'attributes' => array(
                                    'type' => 'submit',
                                    'value' => 'go'
                        ),
                    ));
                }
            }
