如何监听事件并以编程方式突出显示我的印度地图的特定区域？

Question

我希望印度地图和包含区域文本的列表能够相互监听，以便当鼠标指针悬停在某个区域上方时，相应的区域名称会带有下划线，同样，如果我将鼠标悬停在左侧区域的名称，然后地图上的相应区域应以粉红色突出显示。你能帮助我吗？我可以添加代码来侦听悬停事件，但我不确定如何以编程方式突出显示这些区域？我可以监听点击区域和点击区域名称，但如何在选择文本时以编程方式突出显示相应的区域？

Answer 1

我已经使用动态 JS 和 JSON 数据构建了类似的东西。方法非常简单，您必须让设计师在 Adobe Illustrator 中用 SVG 绘制您的印度地图，完成后您需要通过渲染 Canvas 元素的 Kinetics JS 解析该 SVG。

我还在 PHP 中创建了一个简单的解析器，它读取 SVG 数据并将其转换为 javascript 对象。
