我正在处理以前的开发人员在导航中创建的图像地图。它将以英国地图为特色，分割成区域，以导航到网站的部分区域。以前的开发人员使用了 img 地图，但图像地图没有正确使用 css，因为图像地图是一种遗留方法。

下面是代码

<style type="text/css">

#map a {
    cursor: hand;
}

</style>

<div id="mapimage"><img src="ukmap.gif" USEMAP="#map" TYPE="image/png" TITLE="Join your local network" WIDTH=294 HEIGHT=486></div>

 <map id="map" name="map">


    <area shape="poly" id="northern" alt="Northern" title="Northern" coords="123,248,134,271,139,294,141,301,156,321,167,317,183,307,180,288,188,298,205,302,225,290,239,289,248,274,211,229,199,208,176,170,168,170,148,207,123,238" href="#" target="" />

    <area id="wales" shape="poly" alt="Wales" title="Wales" coords="100,302,92,332,110,338,111,355,64,374,88,400,133,398,154,404,164,384,161,372,144,364,145,344,154,321,143,302,103,293" href="#" target="" />

</map>

我们需要每个区域在悬停时改变颜色。最好使用绝对定位的 div 和 ul/li 重新编写它。或者是否可以在鼠标悬停时使用 jquery/javascript 更改 ukmap.gif？因为那时我可以拥有相同的图像，但不同区域的颜色被阻挡，并更改图像以模仿 css：悬停，我不想破坏以前人们的工作，同时如果一个简单的 jquery hack 可以选择这些，我不想浪费时间重写它

“图像映射是一种传统方法”——不正确。HTML 5 规范完全支持 HTML 图像映射。

CSS 根本不适用于图像映射。

试试ImageMapster，一个专门为此目的设计的 jquery 插件。

这是一个基本用法（与其他答案相同的问题 - 区域不匹配，我无法轻松找到英国的准确图像地图，并且没有您的区域匹配的源图像）。但你明白了。

// basic implementation of hotspots with ImageMapster

$('#mapimage').mapster(
{ 
    fillColor: 'ff0000'
});

如果您不想重新启动一切，您可以执行以下操作：将悬停代码添加到每个区域，并更改图像的来源。

$('#southeast').hover(
        function() {
            $('#mapimage img').attr('src', 'http://www.groupswelcome.co.uk/maps/uk_map.gif');
        },
        function() {
            $('#mapimage img').attr('src', 'http://www.alert24uk.com/ESW/Images/uk-map.gif');
        }
    );

这是这个方法的一个小技巧（在右下角向东南翻转）......图像当然与映射不对应。

通过这样做，您将看到一个临时的空白图像......直到图像加载。

有一些方法可以防止这种情况，比如使用 spritesheet。如果有兴趣，我可以为你做一个例子。

这是一个简单的方法。还有其他选择。如果您的网站适用于最近的浏览器，则为 HTML5 画布。

事实上 area in none 的默认显示，因此您必须首先将其设置为display:block，因此使用此 CSS 规则来更改地图区域上的光标：

area{
    display:block;
    cursor:hand;
}

很抱歉在游戏后期跳到这个问题，但我有不规则（非矩形）形状的答案。我使用 SVG 解决了它，以生成我想要附加事件的位置的掩码。

这个想法是将事件附加到内联 SVG，超级便宜，甚至用户友好，因为有很多程序可以生成 SVG。SVG 可以有一层图像作为背景。
