Problem on passing array to ajax request in laravel

I am trying to pass array through ajax request

<input type="text" name="item_name[]">
<input type="text" name="address">

 $(document).on('click', '#save_info', function () {
        var address = $("#address").val();
        var item_name = $("[name^='item_name']");

       $.ajax({
            url: '/save_information',
            dataType: "json",
            type: 'POST',
            data: {
                _token: '',
                address: address,
                item_name: item_name,
          }
        });
    });

In my controller

    $item_name = $request->item_name;
    $array_count = count($item_name);

It makes error. How can i save array value using loop. Thanks in advance
