How to use jQuery .ajax to my form's action

Question

I changed my coding style for php and jQuery, but my Registration

$("#reg_form_company").bind("submit", function() {
    $.fancybox.showActivity();
    $.ajax({
            type     : "POST",
            cache    : false,
            url      : $(this).attr('action'),
            data     : $(this).serializeArray(),
            success  : function(data) {
                $(".printArea").empty().append(data).css('visibility','visible');
            }
    });
    return false;
});

Then this is my Form

<form id="reg_form_company" action="index.php?module=register&actionregister" method="post" >
      <input>[...]</input>
</form>

Then after clicking the "Submit" button, it doesn't work, I assume that somebody can help me to solve this problem, coz the $.ajax might confuse about POST(for inputs) and the GET(for the parameters of the "action" form)

I appreciate for your help, you can also modify the entire jQuery code if it's required.

Sorry guys for not including the #reg_form_company, and the fancybox

File input working ajax

Hi,
the other answers has not worked for me since I needed to pass files inputs and thoses cannot be "serialized".

The good way is to pass it via FormData and disable processData:

$('form').on('submit', function(e) {
    e.preventDefault();

    var formData = new FormData(this);

    $.ajax({
        type       : "POST",
        cache      : false,
        url        : $(this).attr('action'),
        data       : formData,
        success    : (data) => console.log('Data returned from server => ', data),
        contentType: false,
        processData: false
    })
})
