Javascript 将CSS转换延迟2秒

好的，我创建了一个按钮，当鼠标悬停在上面时，它会显示一个菜单。一旦鼠标离开按钮，菜单就会隐藏。这很完美，但当我从鼠标移到菜单本身时，菜单不应该消失。这也在发生，但我已经使用css创建了一个反弹效果，使其更加时尚，如果我在动画发生之前尝试将鼠标悬停在菜单上，菜单将再次隐藏，因为在反弹操作期间菜单和按钮之间存在间隙，所以我想将隐藏延迟2秒，所以，即使有人按下按钮并试图在菜单上移动，它也应该在消失前至少等待2秒

HTML代码

<div id="menu">
            <ul class="menu" id="tempMenu">
    <li class="listOfNumbers"><a id="Menus" href="">Numbers</a><div>
                        <ul class="submenu">

我不知道是否需要使用javascript或jQuery。但是，如果使用它们中的任何一个都可以实现，那么也可以

也许您想要

您可以指定多个延迟；每个延迟将应用于transition属性指定的相应属性，该属性充当主列表。如果指定的延迟少于主列表中的延迟，则缺少的值将设置为初始值（0s）。如果有更多的延迟，列表只会被截断到正确的大小。在这两种情况下，CSS声明都保持有效

看看这个

它说，您可以在任何时候指定一个转换，可以有多个转换，还可以用CSS3做更多的事情。请仔细阅读本教程，它将对您有很大帮助。

CSS的主要变化：

将li的位置更改为“相对”，并删除其子对象的位置固定，以便li的大小将包括其所有子对象；这一步很关键，因为它将使li:hover一直工作，即使鼠标可以移出链接“数字”

在li而不是子菜单上应用z索引，恐怕这应该更合理，因为我们希望整个菜单应该在最前面

但它不会延迟外观、反弹和不透明度。整个运作将陷入混乱。但是感谢你的帮助。投赞成票。我明白你的意思，我也试过了，但由于某种原因，它似乎不起作用，我不知道我做错了什么，你能帮我纠正一下吗。显然，转换在显示属性上不起作用，所以我使用了可见性；-）但它会延迟菜单的显示，但不会延迟隐藏。那么，我怎样才能扭转结果呢。两秒钟后立即显示和隐藏。我认为您的子菜单顶部应该与主菜单按钮重叠一些像素（这是完成模拟的情况）。此外，您应该显示（

display:block

）一个未激活的子菜单包装器（例如

ul.子菜单的父
div
），并在不考虑可见性的情况下执行动画（例如
ul.子菜单上）。所以包装不会被隐藏，因为你把鼠标移出了“敏感”区域。@最后试试抓捕是的，听起来是个好主意。谢谢。动画应该从：hover开始当然（但独立于包装可见性）。我认为标题应该更具描述性，比如“悬停子菜单的延迟动画”等等，以表达悬停元素动画的困境。非常感谢兄弟，但我这一行有很多菜单，我知道我没有在自己的提琴或问题中发布它，但我不能增加div宽度并在那里应用o=hover事件。我唯一的选择是将隐藏事件延迟3-4秒。但是我感谢你的帮助。。向上投票。。
