我目前正在使用David Lynch的maphighlight jquery插件。
link - http://davidlynch.org/projects/maphilight/docs/
我想在图像地图上同时使用两种不同的颜色，并将alwaysOn功能设置为true。
我在下面附上了我的代码段。 其主要功能：
1）悬停时的默认高亮显示为绿色，当您双击图像时，颜色会变为红色。
2）选择颜色后，左键单击，按住mousedown并拖动多个图像区域以突出显示它们。
3）您也可以点击已突出显示的区域以删除突出显示。
我非常需要的另一项功能是：点击并拖动并突出显示多个区域后。当我双击（改变高亮悬停颜色）时，我希望已经突出显示的区域保持不变，而不是改变颜色。
当前的问题是当我双击所有突出显示的区域时会改变颜色。
非常感谢任何关于此的帮助！

答案 0 :(得分：0)
我无法实现我想要的原始功能，但我确实找到了使用maphilight的替代解决方案。我使用“悬停”和“点击并拖动”事件为绿色。之后，我设置了“点击”事件，将点击区域变为红色。通过这种方式，我可以同时打开两种颜色，而没有映射区域具有固定的颜色设置。
我已将代码段与此答案一起附加。以防有人发现它有用。
请注意，此功能仅使用jquery 1.11.1或1.11.2版本进行测试
