如何在 HTML 文件中使用 svg 突出显示整个地图
How to highlight the entire map using svg in HTML file?
这是为map编码。如果我将鼠标悬停在地图上，它只会突出显示一半的状态。我需要突出显示完整状态。怎么办？谁能帮我编码...

这与分层顺序有关。你的中间状态被埋在其他两个状态之下。要将其置于顶部以使边框显示在最顶部，您必须最后插入元素。
快速解决方法是为您的元素提供一个 ID：<svg id="id_svg" ...
然后在 getstate（） 函数中，在末尾插入以下内容：
document.getElementById('id_svg').appendChild( elem );
处理这组复杂性的更好方法是使用像raphaeljs这样的库。它修复了许多烦恼，并且跨浏览器兼容。
