Answer 1

这种情况发生在表单重新加载时（回发发生）...通过在代码中添加“return false”来防止它...所以您的代码就像..

  $('.lightbox').click(function(){
            $('.backdrop, .box').animate({'opacity':'.50'}, 300, 'linear');
            $('.box').animate({'opacity':'1.00'}, 300, 'linear');
            $('.backdrop, .box').css('display', 'block');
             return false;
        });
