javascript - 延迟 CSS 转换 2 秒

Question

好的 所以我创建了一个按钮，当悬停在它上面时会显示一个菜单。一旦鼠标从按钮上移开，菜单就会隐藏。这是完美的，但是当我从鼠标移到菜单本身时，菜单不应该消失。这也发生了，但我使用 css 创建了一个反弹效果，使它更时尚一点，如果我试图在动画发生之前将鼠标悬停在菜单上，菜单会再次隐藏，因为菜单之间有间隙和按钮在弹跳 Action 期间，所以我想延迟隐藏 2 秒，这样即使有人按下按钮并试图在菜单上移动，它也应该至少等待 2 秒才能消失。 Link to fiddle

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

Answer 1

也许你想要transition-delay:https://developer.mozilla.org/en-US/docs/CSS/transition-delay

编辑:

You may specify multiple delays; each delay will be applied to the corresponding property as specified by the transition-property property, which acts as a master list. If there are fewer delays specified than in the master list, missing values are set to the initial value (0s). If there are more delays, the list is simply truncated to the right size. In both case the CSS declaration stays valid.
