我有一张来自 map 的图像，还有来自图像 map 上几个区域(蓝色)的其他几张图像。其他图像代表鼠标悬停时应显示的蓝色区域。但我有一个问题。当我将鼠标放在图像 map 上的区域上时，它们开始闪烁。例如，当我将鼠标悬停在特定区域上时，我想在没有闪烁的 onmouseover 和 onmousemove 的情况下激活蓝色区域。我会放一张 .gif 图片(光标未显示)以显示当我将鼠标光标放在图像上时我遇到的问题，我也会发布代码以查看是否有任何遗漏或必须被改变。

最佳答案
在您的悬停图像上，添加 usemap 以使用相同的 map 。这样它们在显示时就不会触发 mouseout 事件。
请参阅此 fiddle :http://jsfiddle.net/NPFWm/4/
