2 收音机检查或没有检查 - 黑色？

$(function(){
    var cars = $('div[id^="car"]'),
        inputs = $('input[type="checkbox"]');

    inputs.change(function(){
        cars.hide();
        if(inputs.filter(':checked').length === 1)
        {
           cars.filter('#car' + $(this).val()).show();
        }
        else {
           cars.filter('#carblack').show();
        }
    });
});
