为了详细说明@rob.alarcon的答案，你必须记住
.hover方法的API是：由于你没有发布你的代码，我不能给你一个明确的答案，但是你需要记住为“悬停”和“悬停”事件提供处理程序。意思是，听起来您有一个有效的方法来处理鼠标进入元素时触发的事件，但是您是否还为鼠标离开元素时提供了一个事件处理程序？
显然，这不是您想要在生产站点中执行的操作，但您始终可以在这两种方法中抛出
alert()消息，以便您明确知道事件正在被处理。HTH。
To elaborate on @rob.alarcon's answer, you have to remember the API for the
.hovermethod is:Since you didn't post your code, I can't give you a definite answer, but you need to remember to provide a handler for both the "hover in" and "hover out" events. Meaning, it sounds like you have a valid method to handle the event that is triggered when the mouse enters the element, but did you also provide an event handler for when the mouse leaves the element?
It's not something you want to do in a production site, obviously, but you could always throw an
alert()message in both methods so that you know explicitly that the events are being handled.HTH.
