动态添加和删除多个div [英] adding and removing multiple div dynamically

问题描述

有点卡住了.这就是它应该做的.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，该垂直div在当前div和下一个div之间必须为5px宽，但是我无法添加和删除div.我有一个条件来检查div不是最后一个，如果您能帮助的话，我已经在代码中对其进行了注释.这是一个示例 jsFiddle

Im a bit stuck. this is what it suppose to do. When you mouse over a menu item it slides out the next menu and adds a new vertical div which must be 5px wide in between the current div and the next but i can't add and remove the div. i have a condition that checks that the div is not the last on I've commented it in my code if you can help it would be appreciated. here is a sample 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;
    }

推荐答案

听起来像您需要手风琴.为什么不只使用

Sounds like you need accordion. Why not just use one of the million plugins available for jQuery?
