Pune地区谢谢在您的情况下，您应该将地图视为矢量或SVG，然后您可以填充该区域，或者高亮显示该区域，添加笔划。。等等，这可以使用 有很好的支持和易于使用，您可以从这里开始：
备注：您可以添加自己的自定义地图以供使用。如果您想在Mouseover事件中突出显示区域，请检查这些链接 如果您想缩放、增长或收缩，可以使用jquery动画 再看下面的链接, jquery scale：
您可以为每个区域标记创建onmouseover事件，并将区域名称作为javascript函数的参数传递，如下所示
<area shape="rect" coords="0,0,82,126" alt="Sun" href="pune.html" onmouseover="PopName('Pune')">
<script>
function PopName(x) {
alert("This is" + x);
}
</script>
函数PopName（x）{
警报（“这是”+x）；
}
<body>
<p id="p1" onmouseover="change()"></p>
