toggle disabled attribute in jquery

I've a checkbox that enable or disable a select element

Actually I use this simple piece of code that works fine.

$("#filtri").change(function(){
    if ($("#menuContinenti").attr("disabled")) {
        $("#menuContinenti").removeAttr("disabled");
    } else {
        $("#menuContinenti").attr("disabled", "disabled");
    }
});

Is this the best way or is there something like a .toggle() function to switch between disabled/enabled?
