Question

我有点卡住了。这就是它想要做的事情。当您将鼠标悬停在菜单项上时，它会滑出下一个菜单，并添加一个新的垂直div，在当前div和下一个div之间必须是5px宽，但我无法添加和删除div。我有一个条件，检查div不是最后一个我已经在我的代码中评论它，如果你可以帮助它将不胜感激。这是一个示例jsFiddle

    $(document).ready(function () {
        $('.menu-item').mouseenter(function () {
            var curr = $(this).closest('.container');
            var next = curr.next('.container');

            next.animate({ 'left': curr.position().left + curr.width() + 5 });

            if(curr.index() < ($('.container').length - 1)){
                //here i need to add and remove a </div class="spacer"></div> to the right side
                of the current(var curr) div
            }

            var $index = curr.index() + 1;
            $('.container:nth-child(' + $index + ')').nextAll().each(function () {

                $(this).animate({ 'left': curr.position().left + curr.width() + 5 });

            });

        });
    });

.spacer
    {
        background-color:Red; width:5px; height:200px; position:absolute; z-index:1000;
    }
