获取用户在选择中选择的选项的ID

Question

I'm tryin to get the id of an option chosen in a select by a user.

$(document).ready(function(){         
    $(".my_select_class").change(function(){
        var d = $(this).find('option:selected').attr('id');
        alert(d);

        return false;       
    });
});

The id exists cause I display it in my php code but the alert open a white frame without any character, I don't understand why. Maybe because "attr('id')" doesn't work with "find('option:selected')" ?
