Ajax请求返回空数组

I am trying to get the id, where the user clicked, and pass it to my controller via AJAX. For some reason, when i try to show what i am receiving in my controller, it show an empty array.

Any idea why my alert return an empty Array?

JS Function:

function categorySelected(elem) {
    $.ajax({
        url: "/newgallery/creative-fields-click",
        type: "POST",
        data: elem.id
    }).done(function (response) {
        alert(response);
    });
}

PHP:

public function creativeFieldsClickAction()
{
    $idSelected = $this->_request->getPost();
    print_r( $idSelected );
    exit();
}

    Data should be JSON, not integer.

    data: { elemid : elem.id }
    

    Then in PHP data can be found from $_POST['elemid']. In your code it could be like

    $this->_request->getPost()['elemid'];
    

    Or something like that.
