我目前使用David Lynch的maphighlight jquery插件。同時使用maphilight jquery插件保持兩種顏色
鏈接 - http://davidlynch.org/projects/maphilight/docs/
我想有一個形象的地圖上同時上兩種不同的顏色，與AlwaysOn的功能設置爲true。
我附上了我的代碼片段。 其主要特點是：
1）懸停的默認高光是綠色，當你雙擊圖像，顏色變爲紅色。 2）一旦你選擇你的顏色，你左鍵單擊，按住mousedown並拖動多個圖像區域以突出顯示它們。
3）您也可以點擊已經突出顯示的區域來刪除突出顯示。
我非常需要的一個附加功能是：單擊並拖動並突出顯示多個區域後。當我雙擊（改變高光懸停顏色）時，我希望已經高亮顯示的區域保持原樣並且不會改變顏色。
目前的問題是當我雙擊所有突出顯示的區域改變顏色。
任何有關這方面的幫助將非常感謝！
